For each selected PocketGIS component that isalready on the device you will be asked if you wantto reinstall or upgrade.

Recovering the Installation Following a PowerLoss

Windows mobile devices have backup batteries topreserve the contents of the machines main memoryif the main battery runs flat. However, on somedevices it is common to experience the loss ofbackup power as well, which means that the entirecontents of the main memory is lost. Storage cardsto not require battery power to preserve theircontents and you can install PocketGIS onto astorage card, and also keep your map data on thecard, to prevent their loss when power is exhausted.Once the batteries have been recharged or replacedthe software and data on the storage card will beavailable for use (although any software or data onthe main memory will be lost). Although thesoftware is preserved in this circumstance,important installation information, which mustreside in the main memory, is lost which makes thefunctionality provided by PocketGIS components(e.g. GPS Receiver) unavailable. You will also looseyour options settings and the software will return toit’s default configuration.

PocketGIS provides two mechanisms which allow youto restore from total power loss, if all the PocketGIS

1-11


software is installed on a storage card, withouthaving to use a third party backup tool. PocketGIScan now detect and repair the installationinformation in main memory following a power loss.A method to backup your options settings to astorage card is also provided.

Installing PocketGIS for Power Loss Recovery

Firstly you need to insert a memory card (or cards)which has sufficient capacity to hold the PocketGISsoftware (circa 2 to 5 Mb) and all your map data.Some devices have memory expansion moduleswhich function as storage cards and do not loosetheir contents following a power loss. Storage cardsappear on Windows CE devices as “Storage Card”,“Storage Card 2”, etc. Some devices use the name“Compact Flash”, “Drive”, or “Disk” instead.

Install all the PocketGIS software onto the storagecard. When running the PocketGIS installer theActiveSync Application Manager (also known as“Add / Remove Programs”) will ask you if you wantto install the software in the “default applicationdirectory”. Press the N oN oN oN oN o button and select theStorage Card in the dialog that follows. When thesoftware has been transferred to the device awindow will appear asking you to select the locationfor the software (this will happen for eachcomponent). Press O KO KO KO KO K to choose the default folderfor each component which will be in the form“Pocket Systems <component name>” in the “StorageCard” folder. [Note: the only other configurationthat is supported by the power loss recoverymechanism is installing all components into thesame folder, e.g. “\Storage Card\PocketGIS” but it is

1-12


safer to just accept the default]. If the software isinstalled onto a card, removing the card whilstPocketGIS is running will cause the application, andpossibly the operating system, to crash.

When importing data into PocketGIS always chooseto transfer it onto a storage card.

Once you are happy with your options settings, orafter significant changes, select Options Options Options Options Options from thePocketGIS PocketGIS PocketGIS PocketGIS PocketGIS menu and go to the Backup Page. Selectthe storage card you wish to backup your optionssettings to and press BackupBackupBackupBackupBackup. Your options will besaved to the card. Note that only options will bebacked up, data and software will not be backed up.If you change your settings make another backupwhich will overwrite any previous backup on thatcard.

Recovering the Installation Following a Power Loss

Following a complete power loss the PocketGIS itemon the programs menu will no longer be there as theinstallation information will have been lost with themain memory contents. Use the “Windows Explorer”(if on a Handheld PC) or other file explorerapplication and navigate to the location of thePocketGIS application. This will be called“PocketGIS.exe” (it may appear as just “PocketGIS”with an application icon) and will be located in“\Storage Card\Pocket Systems PocketGIS” orwherever you chose to install the software. Doubletap the application icon to run PocketGIS. PocketGISwill detect that the main memory contents havebeen lost and the installation information, includingprogram menu entries, will be restored. [Note:

1-13


PocketGIS Connection will not be able tocommunicate with PocketGIS until this restorationhas been performed]. Following the installationrestoration, your options settings will then be copiedback into the main memory. Note, if you did notmake a backup of your options before the power waslost they cannot be restored.

PocketGIS will now be fully operational.

You view and access map data in PocketGIS via aMap ViewMap ViewMap ViewMap ViewMap View or ViewViewViewViewView. The terms Map View and Vieware used interchangeably throughout this manual.

The Map View determines which map data isdisplayed and how and when it appears on thescreen. The View is literally your view onto the mapdata.

When you open PocketGIS for the first time therewill be no Views available - a View will be created foryou the first time you download some map data.Downloading map data is explained in the PocketGISConnection User Manual.

3-2


The map data that is associated with the View will bedisplayed in the Map Display AreaMap Display AreaMap Display AreaMap Display AreaMap Display Area. You cancontrol the map display using the Pan / ZoomPan / ZoomPan / ZoomPan / ZoomPan / ZoomControlsControlsControlsControlsControls in the main toolbar at the top of thescreen - these controls are also available from theView menu along with other view controls. Thesecontrols are explained later in this chapter.

By default PocketGIS works in Multiple View Mode.However, you can configure PocketGIS to work withsingle Views which simplifies the View menu - this iscovered in Chapter 8 - Multiple View Mode.

In addition to the Pan / Zoom Controls, View Menu,and Map View Controls, there are many other toolswhich operate on map data. These controls aredescribed in the Map Tools and Navigation &Display Tools chapters.

Once some map data has been loaded, a View will becreated and an initial overview of the map data willbe displayed.

The current scale of the map display appears in thetop right hand corner of the PocketGIS screen.

3-3


Pan / Zoom Controls

The Pan / Zoom Controls in the main toolbar can beused to navigate around the Map Display. Thesecommands are also available from the ViewViewViewViewView menu.

Keyboard shortcuts are provided as indicated in themenu and button tooltips.

The button on the left of this control group is theZoom In ButtonZoom In ButtonZoom In ButtonZoom In ButtonZoom In Button.

This button will increase the resolution of the mapdisplay - a smaller area of the map view will bedisplayed at a larger scale. The centre of the displaywill be the same as the previously displayed area.

The button on the right is the Zoom Out ButtonZoom Out ButtonZoom Out ButtonZoom Out ButtonZoom Out Button.

3-4


This button will decrease the resolution of the mapdisplay - a larger area of the map view will bedisplayed at a smaller scale. The centre of thedisplay will be the same as the previously displayedarea.

The four buttons in the centre of this control groupwill pan the display in the direction of the arrow.The display resolution, or scale, will not change butthe display will be centred on a different location.

Depending on the current display position in themap display area, these buttons will be either active- meaning you can pan or zoom in that direction, orbe inactive (greyed out) - meaning that you cannotpan or zoom in that direction. You cannot zoom outif you are at the maximum extent of the map viewarea. You cannot zoom in if you are at the minimumextent of the map view area. Sometimes you will seethat all the Pan / Zoom control buttons are greyedout and therefore disabled. This happens whenthere are no Map Views available, or the map dataassociated with the View is not available (e.g. if itwas on a storage card which you have removed).

You can select ‘Overview’ from the ‘View’ menu - thiswill zoom the map display out to the full extent ofthe data in the map view.

Composition of Map Views

A Map View is comprised of a number of LayersLayersLayersLayersLayers ofMapMapMapMapMap data.

3-5


Geographical map data is stored in a MapMapMapMapMap. EachMap that is loaded into PocketGIS consists of one ormore Layers of geographical data. For example aMap of an urban area may have three Layers - onecontaining roads, another containing buildings, anda third containing railways. Vector Map Layerscontain FeaturesFeaturesFeaturesFeaturesFeatures. A Feature is a graphical elementsuch as a line, point, text, area, etc. Map Views canalso contain Raster Map Layers which display ascanned image of a map.

A Map View can contain any number of Layersdrawn from any number of Maps. i.e. the View cancontain Layers from more than one Map. Also, theView does not need to contain all the Layers fromeach Map.

Each Layer that is included in a View has two otheritems associated with it: a LegendLegendLegendLegendLegend and a DisplayDisplayDisplayDisplayDisplaySchemeSchemeSchemeSchemeScheme.

A Legend defines how the map data is displayed, i.e.it defines line styles and symbols.

A Display Scheme defines at which scale individualmap features are displayed. As you zoom out of amap display features may no longer be displayed inorder to reduce the density of the map display andaid clarity. For example, as you zoom out buildingsmay not be displayed past a certain scale, but roadswould still be displayed.

Legends and Display Schemes are setup usingPocketGIS Connection. The creation andmodification of Legends and Display Schemes isdiscussed in the PocketGIS Connection User Manual.

3-6


The View Menu

The View Menu provides various items which controlthe Map Display Area.

The Zoom / Pan item provides menu based access tothe pan and zoom commands described earlier inthis chapter. The Modify item is described in‘Modifying a View’ later in this chapter. Additionalcommands that can appear on this menu aredescribed in Chapter 8 - Multiple View Mode.

The second part of the View menu contains a list ofthe layers in the current view.

You can use the View menu to turn the display oflayers on and off. If there is a to the left of a Layername, then that Layer is currently displayed. If youtap on the Layer’s name then the map display willredraw without data from that Map Layer. If there isa space on the left of a Layer then that layer is notcurrently displayed. If you tap on the Layer’s namethen the map display will redraw with data from thatLayer.

If a Layer name is greyed out then the Layer cannotbe displayed at the moment. This could be becausenone of the data from that Layer will display at thecurrent scale. For example, if the Layers’ Display

3-7


Scheme was set so none of it’s data was displayedabove a scale of 1:50,000, and you zoomed out to1:100,000 - the Layer’s name would be greyed out.This is nothing to worry about - it’s for yourinformation. If the Map Display Area goes blankafter a Zoom Out operation - check the View Menu tosee if the data has gone out of range.

The Layer name will also be greyed out if the Layer’sMap, Legend, or Display Scheme is missing (if youhaven’t deleted the map then it was almost certainlyon a card you have removed).

Modifying a View

You modify a View via the Modify View dialog. Thisis accessed by selecting the Modify item of the ViewMenu.

3-8


The dialog shows the View’s name and a list ofLayers that the View contains. The buttons at thebottom of the dialog can be used to configure theView’s Layers.

Name

The Name item can be used to change the name ofthe View. Naming Views is useful in Multiple ViewMode which is described in Chapter 8.

Location

The LocationLocationLocationLocationLocation item allows you to choose whetherthe View is stored in main memory or on a storagecard.

Add

The Add Button will display the Add Layer dialog.This dialog can be used to add a Layer to a View.The Add Layer dialog is described later in thischapter.

3-9


Modify

The Modify Button will display the Modify Layerdialog for the Layer that is selected in the Layer list.This dialog is described later in the chapter.

Delete

The Delete button will remove the selected Layerfrom the View.

Up / Down Buttons

These are used to change the priority of Layers inthe View. PocketGIS draws Layers is reverse priorityorder. The Layer at the bottom of the list is drawnfirst, and the Layer at the top of the list draws last.You can use these controls to define the drawingorder, i.e. which layers are drawn over the top ofother Layers. To change the priority of a Layer tapon it’s name in the list and then tap U pU pU pU pU p or DownDownDownDownDown.

Modifying a Layer

To modify a Layer first bring up the Modify Viewdialog as described in the previous section. Selectthe Layer you wish to modify in the Layer list andtap the Modify button. The Modify Layer dialog willbe displayed.

3-10


The dialog shows the Layer’s name and providescontrols which can be used to configure the Layer.

Name

The Name item can be used to change the name ofthe Layer in this View (it does not change the nameof the Layer in the Map).

Legend

This item shows the name of the Legend that iscurrently being used to display the features of thisLayer. Legends control line styles and symbology.The popup list allows you to select from otherLegends that have been created for this Layer.Normally there will only be one Legend available.

Display Scheme

This item shows the name of the Display Schemethat is currently being used by this Layer. DisplaySchemes define at which scales map features aredrawn. The popup list allows you to select from

3-11


other Display Schemes that have been created forthis Layer. Normally there will only be one DisplayScheme available.

Adding Layers to a View

To add a Layer first bring up the Modify View dialogas described in the previous section. Tap the Addbutton - the Add Layer dialog will be displayed.

Use the Map popup list to select the Map from whichyou want to include map data.

Use the Layer popup list to select the Layer whichyou want to add to the View.

The Name item allows you to give the Layer a name.This name does not need to be the same as theoriginal name of the layer.

Tap the Add button to add the Layer.

3-12


Printing a View

You may print the current map display using thePrint command on the PocketGIS menu.

This command will display the standard Windows CEprint dialog which will allow you to select the printerand other options. PocketGIS will centre the currentmap display within the chosen paper size and extendthe draw area to fill the page.

You can extend the printing capabilities of yourdevice by purchasing third party print drivers andsoftware.

Please see the PocketGIS Release Notes document forfurther notes on printing.

Note that at the time of writing, printing is notavailable in the Palm-size PC / Pocket PC version ofPocketGIS.

Chapter 4

Map Tools

This chapter explains how to use tools which interactdirectly with the Map Display Area and MapFeatures.

These tools enable you to:

• Pan / Zoom by pointing.

• Measure distances from the map.

• Measure areas from the map.

• Display the grid reference of a point.

• Display and change information about a mapFeature.

• Change the geometry of a map Feature.

• Capture new map Features.

4-2


The Map Tools Button

The Map Tools Button is located in the main toolbarat the top of the screen.

Tapping the Map Tools Button displays the MapMapMapMapMapTools MenuTools MenuTools MenuTools MenuTools Menu which provides a list of the Map Toolsavailable at the current time.

You use the Map Tools Menu to select which tool iscurrently active. When you tap in the Map DisplayArea the action that occurs depends on which MapTool is selected. The icon displayed on the MapTools Button changes to reflect the selected tool - theMap Tools Menu shows which tool is selected with adot.

When you start PocketGIS the current Map Tool isthe Pan / Zoom ToolPan / Zoom ToolPan / Zoom ToolPan / Zoom ToolPan / Zoom Tool.

You will find that not all the Map Tools are alwaysavailable. Map data can be stored in one of twoformats: Read Only and Read / Write. Since some of

4-3

Map Tools

the Map Tools are used to create and change mapfeatures, if your View does not contain any read /write data then the Geometry and Capture Tools willbe greyed out.

If you have an enhanced or customised version ofPocketGIS you may find that the list of Map Tools isdifferent to that described here. Refer tosupplementary documentation for information onMap Tool Enhancements.

The Pan / Zoom Tool

The Pan / Zoom Tool allows you to pan and zoomthe map display using the pen directly on the MapDisplay Area. This tool should not be confused withthe Pan / Zoom Controls described in the previouschapter.

First make sure that the Pan / Zoom Tool is selected.

If the icon in the Map Tools Button is not thentap the button and select Pan / Zoom .

4-4


You can pan the map display by tapping on the maplocation that you would like to appear in the centreof the display - the screen will then redraw, at thesame scale, with that location at the centre.

You can zoom in to a chosen area by dragging out abox on the display. The display will zoom to showthe area contained within the box you have drawn.You can drag the box in any direction you like (topleft to bottom right, top right to bottom left, bottomleft to top right, etc.).

If whilst you are dragging the box you decide youhave made a mistake, you can abort the zoom in bymoving the pen back to the point you started from -the box will shrink to nothing and you will hear awarning sound - lift the pen and the operation willbe cancelled.

If you choose a pan location which is near the edgeof the maximum view extent, the location will notalways be redrawn in the centre of the display. Themap display is constrained so it will not moveoutside the maximum extent of the View.

4-5

Map Tools

Sometimes you may find that dragging a zoom boxdoes not increase the scale of the map display. Thishappens when you are at the minimum zoom extent.

You can use the Pan / Zoom tool even if it is notselected as the current map tool. If you hold downthe shift key whilst tapping or dragging a pan /zoom operation will be performed. Also the mapdisplay will zoom in, or out, when the user pressesthe numeric keypad add (+, zoom in) or subtract (-,zoom out) keys (if these are present on your device).Some devices have In and Out buttons whichcorrespond to these keys and zoom the display in orout.

The Grid Reference Tool

The Grid Reference Tool will display the coordinateposition of a map location you indicate with the pen.

First make sure that the Grid Reference Tool isselected. If the icon in the Map Tools Button is not

then tap the button and select Grid Reference .

4-6


Tap on the map location for which you want the gridreference.

A small popup will appear showing the gridreference. The position of the grid reference (i.e.where you tapped) is shown by an . The referenceis in the coordinate system of the map data you haveloaded and is displayed in the current Display Units(e.g. meters). You can change the display units inOptions which are described in Chapter 7. The +/-indicates the error in the reference due to screenresolution. In the example shown the error is 1m.

If you tap close to a map feature the coordinate willbe calculated from the underlying map data and willtherefore be entirely accurate. If a map featurecoordinate is displayed you will hear the “OK” beepwhen you tap and the grid reference display will notcontain a +/- error.

If you want another grid reference simply tap in therequired location. If you want the current gridreference to disappear tap the grid reference text.

The Identify Tool

4-7

Map Tools

The Identify Tool will display a description of a mapfeature you select with the pen.

First make sure that the Identify Tool is selected. If

the icon in the Map Tools Button is not thentap the button and select Identify .

Tap on the feature you are interested in. You willneed to tap very close to the feature in order toselect it.

If you hear an error sound then no feature wasselected. If you hear the OK sound then the featurewill be highlighted and a description of the featurewill be displayed in a popup.

4-8


If you want to identify another feature simply tap inthe required location. If you want the currentidentification to disappear tap the featuredescription.

If you have a feature selected in the Identify Tool,and then switch to the Attribute or Geometry tools,the feature selection will be retained.

The Distance Tool

The Distance Tool allows you to measure thedistance between two feature points which you selectwith the pen.

First make sure that the Distance Tool is selected. Ifthe icon in the Map Tools Button is not thentap the button and select Distance .

4-9

Map Tools

The prompt “Tap first point...” will appear at the topof the map display area. Tap on the first featurepoint. If a feature point is not selected then theerror sound will be played. If a feature point isselected then the OK sound will be played and thepoint will be marked with a circle cross. The promptwill change to “Tap second point...”.

Tap on the second feature point. If a feature point isselected then the OK sound will be played and thepoint will be marked with a circle cross. Thedistance between the two points will be displayed inthe current display units as a popup text item.

4-10


If you want to make another measurement simplytap on a feature point and repeat the steps describedabove. If you want the current distance to disappeartap the popup text.

The Area Tool

The Area Tool allows you to measure the areaenclosed by a linear map feature which you selectwith the pen.

First make sure that the Area Tool is selected. If the

icon in the Map Tools Button is not then tapthe button and select Area .

4-11

Map Tools

Tap on the feature whose enclosing area you wish tocalculate. You will need to tap very close to thefeature in order to select it.

If you hear the error sound then no feature wasfound near your tap, or the feature was not a line orarea, or it did not have at least three points.

If you tap close enough to a line or area feature thenyou will hear the OK sound, the feature will behighlighted, and it’s enclosing area will be displayed.If a line feature does not close back on itself the final“closing” segment will be assumed by thecalculation.

4-12


If you want to measure another area simply tap onthe required feature. If you want the current area todisappear tap the popup text.

The Attributes Tool

The Attributes Tool will display the attributesassociated with a map feature you select with thepen.

First make sure that the Attribute Tool is selected. If

the icon in the Map Tools Button is not thentap the button and select Attributes .

Tap on the feature you are interested in. You willneed to tap very close to the feature in order toselect it.

4-13

Map Tools

If you hear the error sound then no feature wasselected. If you hear the OK sound then the featurewill be highlighted and the Attributes Dialog will bedisplayed.

The Attributes dialog shown above is how it willappear for a feature from a read / write map withattributes.

If you have a feature selected in the Attribute Tool,and then switch to the Identify or Geometry tools,the feature selection will be retained. The Attributetool will continue to highlight the currently selectedfeature even after the form has been closed.

Attribute Field Editors

The attribute editors allow you to view, enter, orchange the attribute values. The configuration ofthe attribute edit fields depends on how the datawas configured in PocketGIS Connection - see thePocketGIS Connection User Manual for details.

4-14


Many fields allow you to type in values. If the fieldhas a - tap this to bring up a list of values. Insome cases this will be a list of recent values to saveyou having to type in values again. Some fields areconfigured so you cannot type in a value but canonly select from a popup value list. The date fieldhas a popup calendar - you can also select a dateelement such as month and use the keyboard arrowkeys to step through values. The time field allowsyou to type in numbers or use arrow keys to stepthough values. Other possibilities are a tabbedalphabetic popup; a popup consisting of imageswhich you can select from; sketch and imagebuttons. Sometimes an attribute may have beendefined as read only. You cannot edit read onlyvalues. Some values, such as areas & line lengthsmay have been configured to update themselvesautomatically. On Pocket and Palm-sized PC devicesmany text entry fields automatically adopt title casewithout the need to press the shift or caps key.

Sketch Pad

Sketch attributes allow you to attach a sketch andtype written notes to a feature. Sketch attributesappear with a Sketch button in the Attributes Form.Pressing the Sketch button displays the Sketch Padwhich allows you to enter text and drawings.

4-15

Map Tools

Use the OK or Close (X) buttons to leave the SketchPad which save, or discard, the changes respectively.Note that the Sketch will not be stored in thedatabase until you save the Attributes Form changes.

The Sketch Pad is built from the standard WindowsCE Rich Ink control and so the appearance andcapability of the Sketch Pad differs with theoperating system version. Most of thedocumentation for the built in Ink Writer, NoteTaker, and Notes applications (depending on whichone is available on a particular platform) will applyto the PocketGIS Sketch Pad.

4-16


In all versions you can make the sketch larger bydrawing off the page. All versions also have controlssimilar to those found in word processors forediting, undo / redo, etc.

The version present in the Handheld PC (CE 2.0) letsyou choose the mode from the Tools menu or thetoolbar. You can choose between Ink (drawing andhandwriting), Select (typing and moving drawings),and Space (inserting space into the sketch).

4-17

Map Tools

The version present in the Palm-size PC (CE 2.01 &2.11) lets you choose the mode from the Tools menuor the toolbar. You can choose between Select(typing and moving drawings), Space (insertingspace into the sketch), and neither of these (drawingand handwriting). See the online help for the builtin Note Taker application for more details on usingthe controls.

The version present in the Handheld PC Professional(CE 2.11) lets you choose the mode from the Viewmenu (the toolbar changes with the mode). You canchoose between Typing, Writing, and Drawing. Thisversion also has more advanced controls for

4-18


grouping and editing elements of the sketchdocument such as may be found in word processingapplications - see the online help for the built inInkWriter application for more details on using thesecontrols.

The version present in the Pocket PC (CE 3.0) letsyou choose the mode by pressing, or releasing, thedraw button on the menu bar. You can choosebetween drawing and typing mode. The Edit menuhas conventional editing commands plus a revertoption which will restore the sketch to the state it

4-19

Map Tools

was in when you opened the sketch pad. The Viewmenu allows you to set the mode and the zoomfactor.

Image Attributes and the Image Selector / Browser

Image attributes allow you to attach an image suchas a digital photograph to a feature. Imageattributes appear with an Image button in theAttributes Form. Pressing the Image button displaysthe Image Select window which allows you to selectan image to be assigned to the attribute.

Use the OK or Close (X) buttons to leave the ImageSelector which save, or discard, the changesrespectively. Note that the Image assignment willnot be stored in the database until you save theAttributes Form changes.

4-20


If the Image Capture Options are set (See Chapter 5)additional access to a remote camera or a cameraapplication on your device is possible.

Press the Browse button to display the ImageBrowser which will display images from storagememory - such as a memory card which has beentaken from a digital camera. Navigate to thelocation of the images you want to browse, select oneof them, and press OK. If you are browsing a digitalcamera memory card the images will be in subfolders of the storage card - see your cameradocumentation for details (or just explore). OnlyJPEG image files can be displayed. When you haveselected the browse folder the Image Browser will bedisplayed allowing you to view and select from allthe images at that location.

4-21

Map Tools

The File menu provides the options to browse adifferent folder and also to delete a selected image(you cannot delete an image that has been protectedusing camera or operating system commands).Select the image you want to assign by tapping on itand press OK. You can also double tap the image toselect and assign it in one action. The browser willclose and the selected image will appear in the ImageSelector.

4-22


Press the Select button to select an image file withoutviewing thumbnail images. The chosen file isselected and it’s thumbnail image displayed in theImage Selector window.

The operation of the Browse and Select functions isslightly different when running on a Palm-sized orPocket PC, than when running on a Handheld PC.On a Handheld PC pressing either the Browse orSelect buttons brings up the standard “open file”dialog which allows you to browse to anywhere inthe available storage mediums. On Pocket and Palm-sized PC devices you can only browse to files whichare stored under “My Documents” - this is thestandard operation on these devices. To allow directaccess to images on a storage card removed from adigital camera, the Pocket and Palm-sized PCversions of PocketGIS will automatically detect adigital camera storage card. If such a card isdetected the “open file” dialog will not appear andthe browser will automatically show all the images it

4-23

Map Tools

can find on the card. Similarly the select functionwill display a list of the images on the card whichyou can choose from. If you want to select form filesunder “My Documents” remove the camera card, thebrowse and select functions will then show the “openfile” dialog.

You can clear the assignment of an image bypressing the Clear button in the Image Selector.

Once an image has been selected, the checkboxescontrol what happens when you press OK to closethe Image Selector and make the assignment.

Copy image into the PocketGIS Database will copy theimage file from it’s current location into thePocketGIS Database containing the feature whoseattributes you are changing. If the image is alreadyin the particular PocketGIS Database this checkboxwill be disabled. Delete the original image will removethe image file from it’s current location once it hasbeen copied. If the source image file is protected (by

4-24


camera or operating system command), or the imageis already located in a PocketGIS Database, the deleteoption will be disabled.

Press OK in the Image Selector to complete theassignment and perform any copy and / or deleteoperation. If there was an image previously assignedto the attribute, and it is located in the PocketGISDatabase to which the current feature belongs, youwill be asked if you want to delete the previousimage - this will save storage space if the image is nolonger required.

It is a good idea to always copy images into thePocketGIS Database if you have the storage spaceavailable. If you choose to assign images withoutcopying them you will need to ensure that they areavailable in their original location whenever they arerequired - such as for viewing in the attributes formor export. This requires that the card they arestored on is inserted in the machine (you canremove it in-between times, to take more picturesfor example). Note that if you are working withmore than one storage card in a Windows CE devicethe second card will be called “Storage Card2” (thethird “Storage Card3”, etc) and these names canchange if you take cards out and move them around.If you assign images without copying them makesure the storage card retains the same name inWindows CE - if it was called “Storage Card” whenthe images were assigned, and is later called“Storage Card2”, the images will not be located. Ifyou always use the same slot for the card containingthe images you should be alright.

4-25

Map Tools

Note that the Image Selector / Browser works bestwith JPEG files which have thumbnail imagesencoded within them. Images from digital camerasgenerally have thumbnails.

Attribute Function Button

The Attribute Function Button provides a list ofcommands.

Tap the function button to bring up a menu offunctions.

Note that there may be other commands on thefunction menu which have been provided by plugincomponents.

Defaults

The defaults function will set any empty attributesto predefined values. Attributes which already havevalues are not affected by the defaults function. Thedefaults function will only set values for which thereis predefined default. If selecting this function does

4-26


nothing, or it is greyed out, it is because there wereno default values supplied for these attributes whenthe map data was downloaded.

Revert

If you modify any feature attributes then the RevertFunction will be available.

Selecting the Revert Function will revert the feature’sattributes back to the values held when you openedthe Attributes Dialog. Revert is not undoable - youwill be warned about this before the operation iscompleted.

Undo

You can undo the last change you made to anattribute by selecting the undo function.

Print

To print a list of the attributes for a feature, selectPrintPrintPrintPrintPrint.

Shortcut Functions

There are two shortcut functions on the menu.

The Geometry Shortcut function will switch from theAttributes Tool to the Geometry Tool for thisfeature. This allows you to edit the current featuresgeometry without having to choose the Geometry

4-27

Map Tools

Tool in the Map Tools Menu, or select the featureagain. The Geometry Tool is described later in thischapter.

The Capture Shortcut function will switch from theAttributes Tool to the Capture Tool. This allows youto start capturing new map features without havingto choose the Capture Tool in the Map Tools Menu.The Capture Tool is described later in this chapter.

Feature Type

The Feature Type popup is in the top left handcorner of the Attributes Dialog and allows you tochange the type of a feature.

Changing the feature type can cause attributeswhich are not defined on the new feature type to bediscarded. You will be warned about this before thefeatures type is changed.

Other forms of the Attributes Dialog

The appearance of the Attributes Dialog is differentfor different types of data. All the examples shownso far are for read / write data with attributes.

If a read / write feature without attributes is selectedusing the Attributes Tool the Attributes Dialog lookslike this:

4-28


Notice that the Feature Type popup and functionbutton are still available.

If a feature from a read only map is selected theAttributes Dialog will look like this:

The attributes are displayed but you cannot changethem.

The Geometry Tool

The Geometry Tool allows you to modify thegeometry of a map feature.

First make sure that the Geometry Tool is selected.

If the icon in the Map Tools Button is not thentap the button and select Geometry .

4-29

Map Tools

When the Geometry Tool is active the GeometryToolbar appears at the top of the screen.

You can move the Geometry Toolbar by dragging the“gripper” on it’s left hand edge.

Select the feature you want to modify. You will needto tap very close to the feature in order to select it.

If you hear the error sound then no feature wasselected. If you hear the OK sound then the featurewill be highlighted.

If you have a feature selected in the Geometry Tool,and then switch to the Attribute or Identify tools,the feature selection will be retained.

4-30


The example above shows the Geometry Tool when aline feature has been selected.

The feature type is displayed at the top of the screen- in this case “General Line Detail”.

If you tap the Geometry Function Button a menu ofedit actions is displayed.

4-31

Map Tools

The items in the first group change the current editaction, nothing happens until you interact with themap display. The items in the subsequent groupsare performed immediately and do not change thecurrent edit action. Select the action you requirefrom the menu. If the item you select is in the firstgroup then the button’s icon will change to indicatethe current edit mode.

Note that there may be other commands on thefunction menu which have been provided by plugincomponents.

Each of the points that make up the line will havebeen highlighted with a symbol. The meaning ofthese symbols is as follows:

4-32


The round cross indicates the current edit point.This is the point that Move and Add edit actionsapply to.

The square cross indicates the backward edit point.The significance of this is described below.

The normal cross is used to highlight the position ofthe other points of the line.

You can change the current edit point (the one withthe circle) by tapping very close to one of the otherpoints in the line.

In the above example the next point was tapped.This point then becomes the current edit point andis highlighted with a circle.

4-33

Map Tools

Move

To move a point first make sure that Move Point isthe current edit action and the point you wantmoved is highlighted with the circle symbol. If thecurrent edit action is not Move Point , tap theFunction Button and select Move Point from themenu.

Next tap on the location you want the current editpoint moved to. The display will adjust to show themodified geometry.

You can select the Undo Function to reverse any ofthe geometry actions.

4-34


Selecting Undo in the example above will reverse theMove Action.

Add

The Add action will add a new point to the line. Thepoint will be added between the current edit point(shown by the circle symbol) and the backward editpoint (shown by the square symbol).

4-35

Map Tools

To add a point first make sure that Add Point is thecurrent edit action and the current and backwardedit points are either side of the line vertex that willcontain the new point. If the current edit action isnot Add Point , tap the Function Button and select AddPoint from the menu.

Next tap on the point you want to add. The displaywill adjust to show the modified geometry.

Add Before

The Add Before action works in exactly the same wayas the Add action, except that the point is insertedbefore the current edit point, rather than after it.The example below shows what happens if exactlythe same point is chosen for the add, but with AddBefore selected as the edit action.

4-36


Delete Point

Selecting Delete Point from the Function Menu willdelete the current edit point, i.e. the point shownwith circle symbol. If this action was selected usingthe example above the line would be modified andappear as shown in the next example.

Delete Feature

The Delete Feature Function will erase the feature.

4-37

Map Tools

You can undelete the feature by selecting the UndoFunction. You must, however, do this immediatelyafter the delete operation.

Snapping

The Snap Button is a toggle, press it once to push itin, press it again to release it. When the Snap buttoncontrol is depressed, the points you enter duringadd and move operations will be snapped to existingmap geometry. The new point will either take theexact coordinates of a snapped to point, or a lineintersection will be calculated for a snapped to line.You can also toggle snapping by typing Ctrl+S.

Snapping only occurs within a certain (very small)tolerance so you will need to tap very close to apoint or line in order to snap to it.

You will have noticed that when you enter a move oradd point you hear an OK sound. When the snapcontrol is checked you only here the OK sound whenthe new point position is snapped. If a point or linewas not found within the search tolerance, the newpoint is still used - but a warning sound is playedinstead.

Snapping does slow down the edit operations so youshould only have the snap control depressed whenyou want snapping to happen.

If you have a customised version of PocketGIS thesnap control may not be visible.

Shortcut Functions

There are two shortcut functions on the bottom ofthe Function Menu.

The Attributes Shortcut Function will switch fromthe Geometry Tool to the Attributes Tool for thisfeature. This allows you to edit the current featuresattributes without having to choose the AttributesTool in the Map Tools Menu, or select the featureagain. The Attributes Tool is described earlier inthis chapter.

The Capture Shortcut Function will switch from theGeometry Tool to the Capture Tool. This allows youto start capturing new map features without havingto choose the Capture Tool in the Map Tools Menu.The Capture Tool is described later in this chapter.

Ending the Edit

When you have finished editing the feature, or wishto select a different feature, press the End Editbutton (or type Ctrl+E).

Map Tools

Editing Areas

Editing area features is the same as editing lines.The area function menu has the same options as theline menu.

Editing Points

If you use the Geometry Tool to select a point, aslightly different version of the Function Menu isavailable. The principles and main controls are thesame as for line features.

The Move action allows you to tap on a new locationfor the point.

The Delete Feature action will delete the point.

Revert works exactly as described for line featuresabove.

If you have selected a rotated symbol an additionaloption, Rotate , will be available.

4-40


To rotate a point first make sure that Rotate is thecurrent edit action. If the current edit action is notRotate , tap the Function Button and select Rotatefrom the menu.

Tapping points in a circle around the point willcause its rotation to change.

Editing Text

Editing text features is the same as editing points.The text function menu has the same options as thepoint menu.

Setting Points With GPS

You can use the Geometry Tool to move or addpoints using coordinates from a GPS receiver. To dothis you need to connect PocketGIS to a GPS receiver.See Chapter 9 for instructions on how to connect toa GPS receiver.

4-41

Map Tools

While you are connected to a GPS receiver the GPSbutton is enabled.

You can tap the GPS button at any time instead oftapping on the map display - the current GPSlocation will be used to digitise the next point. (Youcan also type Ctrl+G). If the edit action is “move”then current edit point is moved to the GPS position;for other modes a new point is added at the GPSposition.

The GPS button will only remain enabled while theGPS receiver is reporting a valid position.

4-42


The Capture Tool

The Capture Tool allows you to create new mapfeatures.

First make sure that the Capture Tool is selected. If

the icon in the Map Tools Button is not thentap the button and select Capture .

When the Capture Tool is active the Capture Toolbarappears at the top of the screen.

You can move the Capture Toolbar by dragging the“gripper” on it’s left hand edge.

First select the type of feature you wish to capture -tap on the Feature popup.

4-43

Map Tools

A list of feature types will be displayed. Thecontents of the list will depend on which featuretypes are included in the current Map View. Note:only features from read / write maps are included inthe list, also some features may have beenconfigured so they cannot be captured.

Select the feature type you wish to capture.

Note: when you re-enter the Capture Tool it willnormally default to the feature type you lastselected.

The Snap Button works in exactly the same way asalready described for the Geometry Tool. The snapcontrol may not appear if you have a customisedversion of PocketGIS.

The Function Button provides a menu of commandswhich are appropriate at various stages during thecapture process. The icon in the function buttonchanges depending on whether the capture featureis a line, point, text or area. Note that there may beadditional commands on the function menu whichhave been provided by plugin components.

To capture this feature, which is a line, tap on thelocation of the first point. The point location will beshown with a circle cross.

4-44


Then tap on the remaining points in the line.

At any time you can press the Function Button toselect any function that is available at that stage ofthe capture operation.

The Create function will create the new feature.

The Close and Create function will add a final pointwhich is the same as the first point (thus closing theline back on itself) and create the feature.

4-45

Map Tools

The Devices sub-menu is described in the GPS andLaser Rangefinder chapters.

The Undo function will undo the last change to thefeature.

The Cancel Capture option will discard all the pointsthat have been captured for this feature (previousfeatures will not be affected).

The Pause function allows you to pause capture ofthe current feature. When you select this functionthe current geometry will be saved and the CaptureTool will appear as if no geometry has beencaptured. You can then capture another featurewhich can be of another type. You can pause asmany features as you like.

The Resume sub menu provides a list of all pausedfeatures. The features are listed in the order thatthey were paused (i.e. the last feature paused will beat the end of the menu) and the menu item gives thefeature type and the number of geometry pointscaptured in brackets. To resume capture of afeature select it from the Resume menu.

The Delete Last Point function will remove the lastpoint that was captured.

4-46


You can also press the End Edit button (or typeCtrl+E) to create the feature.

Once you have created the new feature it will behighlighted and the Delete Feature function will beavailable from the function menu.

If you have a feature selected in the Capture Tool,and then switch to the Attribute, Identify orGeometry tools, the feature selection will beretained.

The Shortcut Functions

When a feature has been created the two shortcutfunctions will be available from the Function Menu.

The Attributes Shortcut Function will switch fromthe Capture Tool to the Attributes Tool for thisfeature. This allows you to edit the new features

Map Tools

attributes without having to choose the AttributesTool in the Map Tools Menu, or select the featureagain. The Attributes Tool is described earlier inthis chapter.

The Geometry Shortcut Function will switch from theCapture Tool to the Geometry Tool for this feature.This allows you to edit the new features geometrywithout having to choose the Geometry Tool in theMap Tools Menu, or select the feature again. TheGeometry Tool is described earlier in this chapter.

Capture Information Display

When capturing line or area features a displayappears in the bottom right hand corner of thescreen. This displays the length of the last vertexand the total length of the the line. The last vertexlength is the value displayed at the top. If a GPSposition is available the distance from the GPSlocation and the last captured point is also displayed- prefixed by “G:”.

Capturing Area Features

If you select an area feature from the Feature popupthe Capture Function Menu will be configured forareas. Capturing areas is almost the same ascapturing lines except:

• You must capture at least 3 points before youcan create an area.

4-48


• The area “Create” function is a close & create.The feature is always closed back on itself. Thismeans that you do not need to capture the last“closing” point of an area.

Capturing Point Features

If you select a point feature from the Feature popupa the Capture Function Menu will be configured forpoints.

Tap on the location of the new point feature, if thisis a non rotatable point then the new feature will becreated immediately.

As for lines, the Point function menu will allow youto delete the newly created point.

Capturing Rotated Points

You capture rotated points by entering two taps.

The first tap defines the location of the point.

4-49

Map Tools

A second tap indicates the rotation angle of thepoint. On the second tap the point feature will becreated. If you select the Create Function, press theEnd Edit Button, or type Ctrl+E after the first tap, thepoint feature will be created with no rotation.

You can only rotate a feature that has beenpredefined as rotatable.

Capturing Text Features

You capture text features in exactly the same way aspoint features.

Capturing Another Feature

When you have captured a feature using the CaptureTool, you can immediately capture another featureby tapping it’s location on the map display. If thenext feature is of a different type to the first, use thefeature popup to select the new type.

Capturing GPS Points

You can use the Capture Tool to capture coordinatesfrom a GPS receiver. To do this you need to connectPocketGIS to a GPS receiver before you open theCapture Tool dialog. See Chapter 9 for instructionson how to connect to a GPS receiver.

4-50


While you are connected to a GPS receiver the GPSbutton is enabled.

You can tap the GPS button at any stage of a captureoperation instead of tapping on the map display -the current GPS location will be used to digitise thenext point. (You can also type Ctrl+G).

The GPS button will only remain enabled while theGPS receiver is reporting a valid position. If thereceiver cannot provide the position then the GPSbutton will temporarily become disabled. It will bere-enabled again once the GPS position has been re-established. GPS receivers often loose track of yourposition when their view of the satellites is obscuredby buildings or trees.

Edit Functions

This section explains how to use the “Edit Functions”available in the Geometry & Capture Tools.

The edit functions described in this section are:

• Aligned Offset

• Bilaterate Point

• Parallel Offset

The prompt will have changed to ask you to tap onthe point on the existing feature where the parallelline should end. You will then be asked to enter theoffset distance between the existing feature and thenew parallel line.

Enter the distance between the existing feature andthe new parallel line and press Enter .

The offset is made to the “right” of the feature, ifyou want the offset to be to the “left” then enter anegative offset. The provisional parallel line will bedisplayed together with a dialog which allows you toaccept the parallel line or flip it to the other side ofthe existing feature.

On completion the new points of the parallel linewill be added to the current capture feature.

4-58


Enter Point

The Enter Point function allows you to enter a newor changed point by typing the coordinate.

To use this function first select Enter Point from thecurrent tool’s function menu. You will be promptedfor the coordinate values.

If you are capturing a feature, a new point will beadded to the current feature. If you are modifyingan existing feature in the Geometry Tool then thecurrent edit point will be moved (or inserted) usingthe supplied coordinate.

The Selection List

When using the Identify, Area, Attributes andGeometry tools you can choose to see a list offeatures found within the search tolerance. Toenable the selection list tick the “Show list whenseveral features found” box in the Map Tools page ofthe PocketGIS Options sheet. By default the selectionlist is disabled.

When the selection list is enabled, and more thanone feature is found within tolerance of a screen tap,a list of the features is displayed.

Create Simple Map

The Create Simple Map tool provides a functionwhich can create a new, empty, map with a singlefeature. Simple Map features do not have attributes.This allows you to create add-hoc geometry whichmay be useful when using GPS or a laserrangefinder.

The Create Simple Map option can be found on theTools->Create sub menu.

Selecting will bring up the following dialog.

The Type item lets you choose the type of the featurein the simple map. Possible options are Point, Line,and Area.

The Location item allows you to create the map in

the devices Main Memory or a storage card if youhave one installed.

The Units item lets you specify the units that thecoordinate data will be stored in. A likely choice iscentimetres. Note that PocketGIS stores points inintegral units (i.e. whole numbers) so if you, say,chose meters then all points would be stored to thenearest meter. You can use the PocketGIS options todisplay values in any units irrespective of the mapdata units.

The Cancel button quits the dialog.

When you have made your choices press Next toproceed to the next dialog.

Use the Name item to give the map a name. Thisname must be unique.

Use the Min X , Max X, Min Y, Max Y items to specify thecoordinate bounds of the map. Note that the unitshere are the current PocketGIS display units, not themap units selected in the first screen. (See Chapter7 for more information on the display units settingof PocketGIS).

The Back button will return you to the first dialog.

Press the Create button to create the new map. Themap’s layer will be added to the current view

The Create Grid tool provides a function which cangenerate a map grid within an existing map.

The Create Grid option can be found on the Tools->Create sub menu.

Selecting will bring up the following dialog.

The Map, Layer , and Feature items allow you to selectthe map feature for which the grid lines will begenerated. You need to create the map and featurefor the grid before you use the Create Grid function.You can create the map in PocketGIS Connection orby using the Create Simple Map function. The gridlines can only be created for line or area featuresand so the Feature popup list will only list line orarea feature types. If the selected map layer doesnot contain any line or area features then thefeature list will be empty.

6-6

The Cancel button quits the dialog.

When you have made your choices press Next toproceed to the next dialog.

Use the Min X , Max X, Min Y, Max Y items to specify thecoordinate bounds of the grid. Note that the unitshere are the current PocketGIS display units. (SeeChapter 7 for more information on the display unitssetting of PocketGIS). These fields will beautomatically filled in with the maximum extent ofthe selected map. The grid cannot extent outsidethe map extent.

Use the Interval item to specify the interval of thegrid.

The Back button will return you to the first dialog.

Press the Create button to create then new grid.

If you selected a line feature then the grid will beformed from straight lines. If you selected an areafeature then the grid will be made up of square areafeatures.

Setting up a System of Scale Dependent Grids

You may wish to set up a system of grids whichappear at different scales. For example, you maywant a 1Km grid to display at 1:5000 and a 10Kmgrid to display at 1:25000.

You can achieve this by defining an appropriateTranslation Scheme in PocketGIS Connection (see thePocketGIS Connection User Manual for informationon how to setup Translation Schemes and generatingempty maps). The Translation Scheme can be set upwith features for the 1Km and 10Km grids. ADisplay Scheme can be created and setup so thesmall scale grid does not display at larger scales andcorrespondingly the large scale grid does not displayat small scales. A legend could be created so thegrid lines appear in different colours. The PocketGISConnection New Map will generate a map inPocketGIS - you can use the Create Grid function togenerate the grid lines for the 1Km and 10Km gridfeatures.

Log to File

The Log to File function will save any data receivedvia a serial connection to a file. It can be accessedfrom the Tools->LoggingTools->LoggingTools->LoggingTools->LoggingTools->Logging menu.

6-8

The Connect ToConnect ToConnect ToConnect ToConnect To item allows you to select the serialport the data is to be received on.

The Fi leFi leFi leFi leFi le item shows the file that the data will bestored to. Data is appended to an existing file. Thefile can be changed using the BrowseBrowseBrowseBrowseBrowse button.

The OptionsOptionsOptionsOptionsOptions button displays the port settingoptions.

The ConnectConnectConnectConnectConnect / DisconnectDisconnectDisconnectDisconnectDisconnect button opens theconnection to the serial port and starts saving datato the file; or disconnects from the port and closesthe file.

Data is saved exactly as it is received with noprocessing.

Log to Feature

Log to Feature allows you to automatically createpoint features and set attribute values from externaldata sources such as sensor equipment. Theposition of the feature is taken from the current GPSposition so a GPS receiver must be connected and beproviding an acceptable position.

Two items are provided on the Tools->LoggingTools->LoggingTools->LoggingTools->LoggingTools->Loggingmenu to control logging to features:

You need to make thesesettings the first time you use a logging device orwhen you change which type of device is being used.You can also use this to connect and disconnect thedevice. To save all settings press the ConnectConnectConnectConnectConnectbutton to establish the connection to the device.Once the current settings are saved the device willbe connected automatically when you press the Logto Feature StartStartStartStartStart button (see below) so you don’tneed to manually connect the device each time youstart logging.

6-10


Log Data to FeatureLog Data to FeatureLog Data to FeatureLog Data to FeatureLog Data to Feature allows you to select thefeature that will be created by the logging. Onlylayers / features in the current View are displayed.Pressing the Start Start Start Start Start button will commence logging.Each log reading from the external device will createone feature (adjust the device to control thefrequency of feature creation). The system“acknowledge” beep will sound for each successfulfeature, if there is a problem (e.g. storage full, noGPS position) then the system error beep will soundfor each reading. If logging is in progress the buttonwill become Stop Stop Stop Stop Stop and you can use this to stoplogging. Logging will also stop if the logging deviceis disconnected.

Log to Feature controls also appear on the Devicesmenu of the various map tools. The items aresimilar to those accessed from the Tools menu whenthe device is not connected, or logging is not started,but act as quick action functions when logging is inprogress. So Connect Logging Device becomesDisconnect Logging Device which disconnects thedevice and stops logging without showing a dialogwindow. Likewise Log Data to Feature becomes StopLog Data to Feature.

Data from the external reading is automaticallyassigned to the features attributes base on theInternal Name of the attribute. Any auto setattributes are also assigned. If a given attribute ismissing that data will not be logged. Attributes areas follows:

Radiodetection RD4000

The depth value is assigned to an attribute whoseinternal name is Depth.

Options

Metric Conversion

This option determines the factor used to convertbetween metric and imperial (miles, feet, inches)units. The international standard for suchconversion is 1 inch = 2.54 centimetres. However,usage in the United States is commonly 1 metre =39.37 inches. Although the difference between thesefactors is small it does make a difference whencalculating coordinates and it is important that thecorrect setting is chosen.

If you are working in metric units for both mapstorage and display, or entirely in imperial units,then no metric / imperial conversion will take placeand this setting will not be used.

Note that this setting only applies to conversionswithin the PocketGIS main application and can beapplied when freehand digitising or displayingcoordinates, distances, areas etc. The unitconversion for calculating GPS positions in feet is setfrom within the GPS Receiver options. The LaserRangefinder module does not have a conversionfactor setting and you should configure your lasermeasurement device to work in metric or imperialunits depending on which is used to represent yourdata.

Multiple View Mode

This chapter describes how to use PocketGIS in“Multiple View Mode”.

By default, PocketGIS operates in Multiple ViewMode. This mode is useful if you are working withdifferent sets of map data which you want to accessseparately. Map Views are explained in Chapter 3.

You may wish to switch the application into SingleView Mode which will simplify the View menu byremoving the items related to multiple views.

As the relationship between a Map Layer, Legend,and Display Scheme is maintained in a View, you canalso use this mode to access the same map datausing different Legends & Display Schemes.

Enabling Multiple View Mode

To enable Multiple View Mode, first select Optionsfrom the PocketGIS menu to open the Options dialog.

GPS Receiver

This chapter explains how to connect a GPS receiverto PocketGIS.

The GPS Receiver component will work with externalGPS receivers supporting the NMEA protocolconnected via a serial port or card slot.

The GPS connection is controlled from the GPSReceiver dialog which is accessed via the GeneralTools Menu.

Selecting GPS Receiver will display the GPS Receiverdialog.

Height Data

Note that heights displayed and stored by PocketGISare ellipsoid heights, with the exception of OSGB andDanish coordinates.

UK GPS

If the map projection is set to “OS Great Britain” GPScoordinates will be shifted according to the OSTN02model. Also note that for OSGB, heights arecorrected to the OSGM02 model.

Danish Projections

Use of the Danish projections requires theinstallation of the Danish Datum Tables from themain installer.

Supported NMEA Position messages

GPS Receiver can receive position information fromthe NMEA GGA, GLL, GGQ and GST sentences.

9-3

GPS Receiver

Only use GGL if your receiver does not support GGAor GGQ. If GGQ or GGA sentences are being receivedthen GLL sentences will be ignored. Note that GLLsentences do not supply data quality or heightinformation and this will not be displayed, stored, orfiltered on.

You can choose to use either, or both, the GGA andGGQ sentences. The GGA sentence does not providecoordinate quality values, and GGQ does not provideHDOP values. Otherwise they are the same. If youwant access to both HDOP and coordinate qualitythen set your receiver to output both of these. Notethat presently, GGQ sentence support is fairly rare.

The Omnistar OMNIPOSA message is supported soposition standard deviation values can be received.This message can be used in conjunction with GGAand / or GGQ messages if HDOP and coordinatequality values are required.

For best results set the NMEA sentences to output atleast once per second. Any less than this and GPSReceiver will report “No GPS Input” regularly. Thetimeout is deliberately tight to ensure that the GPSposition used by PocketGIS is correct.

Windows Mobile GPS Program Port

PocketGIS can connect to a GPS Receiver controlledby the GPS Settings panel in Windows Mobile 5 andlater.

9-4


To enable this follow the Windows Mobiledocumentation and ensure that the GPS ProgramPort is a COM port (do not select a GPD port). Onceenabled this COM port can be selected as the GPSport in PocketGIS.

Unless you need the GPS location data to be used inmore than one application at once there is nobenefit in using the Windows Mobile GPS ProgramPort. It is recommended that “Manage GPSautomatically” is unticked in the Access page ofWindows Mobile GPS Settings and that you connectto the GPS device or port directly.

Recommended Port Speed

If the receiver is only configured to output NMEAGGA or GGL sentences then a port speed of 9600 bpsshould be sufficient. If the receiver is configured tooutput many messages or a combination of GGA,GGQ or manufacturer specific messages then it isrecommended that you use the fastest speedavailable. If PocketGIS appears to be droppinginformation (e.g. HDOP or coordinate quality) thenthis can be due to the data not being receivedquickly enough. PocketGIS deliberately puts a verytight limits on the frequency that messages must bereceived to ensure that the data is current andaccurate.

GPS Protocols

The GPS Receiver component currently supports‘NMEA’, ‘Ashtech NMEA’ and OmniSTAR HPprotocols. The Ashtech protocol includes standard

9-5

GPS Receiver

NMEA support and also provides Ashtech specificmodem dialup functionality. If you need protocolsupport which is not currently provided pleasecontact [email protected].

Position Standard Deviation Support

If available from the receiver, position standarddeviation values in metres are displayed by the GPSmonitor. You can also filter on these.

Setting Up GPS Receiver

Before you can use GPS Receiver you must set all theconfiguration options. If you try and connect to aGPS Receiver without visiting each options page youwill be prompted to check any remaining options.When you visit an options page default settings willbe shown - you can accept these defaults withoutmaking any changes - just move to the next page orpress OK.

To ensure that the projected coordinates which aredisplayed and stored by PocketGIS are accurate, youshould carefully check how the GPS Receiver optionsare configured. In particular make sure that the“Convert” options are set correctly. It is advisablefor you to check that positions reported byPocketGIS are consistent with your expectation and /or known positions.

coordinates” are checked, then the originalcoordinates will be displayed first, followed by theconverted values.

Port Options

This group of options allows you to setup thecommunications port for use with the GPS receiver.You need to consult the manual that came with yourGPS receiver in order to determine the correctoption values. The settings of both the receiver andPocketGIS must match exactly.

Speed

Set the speed, in bits per second, to the speed thatyour GPS receiver outputs data.

If the receiver is only configured to output NMEAGGA or GGL sentences then a port speed of 9600 bpsshould be sufficient. If the receiver is configured to

9-9

GPS Receiver

output many messages or a combination of GGA,GGQ or manufacturer specific messages then it isrecommended that you use the fastest speedavailable. If PocketGIS appears to be droppinginformation then this can be due to the data notbeing received quickly enough. PocketGISdeliberately puts a very tight limits on the frequencythat messages must be received to ensure that thedata is current and accurate.

Settings

Set this to the character format that your GPSreceiver uses to output data. The options show:number of data bits / parity / number of stop bits.

Projection Options

This page lets you specify the map projection thatthe geodetic coordinate output from the GPSreceiver are translated to. This must be the sameprojection as the map data you are using.

9-10


Projection

Select the map projection that you are using. Youcan choose between Universal Transverse Mercator(UTM) and a number of national projectionsincluding the Ordnance Survey (OS) projection.

Note that some projections require that datum tablesare installed. You will be warned if you select aprojection that requires tables that are not present.Any such datum tables will be shown in the productinstaller when you choose a custom installation orthe modify option - see Chapter 1.

Datum

For many projections this simply displays thegeodetic datum used by the selected projection. Forsome projections, such as UTM, this item allows youto specify which datum should be used.

Units

This item specifies the distance units generated bythe projection algorithm. For most projections thiswill be preset to the correct value and you will notbe able to change it. For some projections, such asUTM, you can select the units.

9-11

GPS Receiver

The choices are Metres, International Feet, and USFeet. The difference between International and USFeet is the factor used to convert from metres (inwhich the calculation is performed) and feet.International Feet uses the factor 1 inch = 2.54cmand US Feet uses 1 metre = 39.37 inches. Althoughthe difference between these factors is small it doesmake a difference and it is important that thecorrect setting is used.

Convert Options

Your GPS receiver will output position data in aparticular datum. If this datum is the same as theone you have selected in the Map Projection pagethen PocketGIS can use the GPS data directly.However, if the datum output by the receiver isdifferent to the one used by the PocketGIS mapprojection, you must configure the Convert Datumsettings so PocketGIS can make the necessaryadjustments.

It is important that you consult the manual thatcame with your GPS receiver very carefully. SomeGPS receivers only output data in the WGS-84datum. Other receivers will output in a datum ofyour choice. If the receiver has controls which allowyou to choose a datum for coordinates on thereceiver’s own display - you should check to see ifthe receiver also outputs data using this datum (THEDISPLAY AND OUTPUT DATUMS MAY BEDIFFERENT!).

Use the Input Datum popup to specify whether thedata input to PocketGIS from the GPS receiver is inthe same datum as the Map Projection, or whetherthe datum will need to be converted. The InputDatum item specifies the datum that the GPS receiveris using. This is the datum that the GPSThis is the datum that the GPSThis is the datum that the GPSThis is the datum that the GPSThis is the datum that the GPSreceiver is using to output data, not thereceiver is using to output data, not thereceiver is using to output data, not thereceiver is using to output data, not thereceiver is using to output data, not thedatum you wish to use in PocketGIS.datum you wish to use in PocketGIS.datum you wish to use in PocketGIS.datum you wish to use in PocketGIS.datum you wish to use in PocketGIS.

The possible values for Input Datum are dependenton the datum of the current projection (the T oT oT oT oT oitem). Possible options are the datum of the mapprojection, and one or more WGS84 based option.

‘WGS84 - ITRS 2000 (now)’ indicates that the inputposition will be corrected for continental drift. Ifthis is not available for the selected projectiondatum the option ‘World Geodetic System 1984’ is

GPS Receiver

given. This indicates that a WGS84 (or indeed ITRS)position is expected but that no compensation forcontinental drift is included.

The ViaViaViaViaVia item specifies whether an initial datumconversion is to be applied. At present this is onlyavailable for correcting the input position to ITRS 89/ ETRS 89 before the position is transformed to thedatum selected on the Projection options page.

Sometimes datum conversion takes place via anintermediary datum such as ETRS89. If this is thecase the intermediary datum can be selected as theInput Datum. So, for example, if an ETRS89 positionwas being supplied to PocketGIS by equipment thatperforms this transformation (or comes from acorrection service that provides ITRS 89 / ETRS 89),and outputs positions in ITRS 89 / ETRS 89 youwould choose ‘European TRS 1989’ as the inputdatum. ie. The software will not perform thecorrection because it has already been applied.Conversely if a WGS84 / ITRS2000 position werebeing supplied you would select ‘WGS84 - ITRS 2000(now)’ as the input datum - ETRS89 would becomethe Via datum as PocketGIS would do the conversion.

If the position is being received from equipment thatoutputs a ‘current’ WGS 84 - ITRS 2000 (now)position then the Input Datum Input Datum Input Datum Input Datum Input Datum item of theConvertConvertConvertConvertConvert page should be set to ‘WGS-84 - ITRS 2000(now)’.

If you are using a low accuracy (e.g.. 10m) GPSreceiver then select ‘WGS-84 - ITRS 2000 (now)’. Inthis case the ViaViaViaViaVia setting does not matter as thedifference will be tiny compared to the overallaccuracy of the position.

9-14


The GPS Receiver component has preprogrammedvalues for datum transformations from WGS84 tothe datum of the selected coordinate system.However you may, if you wish, specify customvalues. If you do you should ensure that the valuesare correct, the responsibility for ensuring this is100% yours.

If the input datum differs from the T oT oT oT oT o datum thenthe Parameters button will be enabled and pressing itdisplayed the Transformation Parameters window.

By default the parameters are set to use thepreprogrammed values in the GPS receiver moduleand it is these values that are displayed. If you wishto use your own parameters untick the “Usestandard values” box and type in the requiredvalues. Press OK to save your new parameters andbe sure to press OK on the main options window tosave your changes. To revert to the standardparameter values open the TransformationParameters window and tick “Use standard values”.If you change the current coordinate system ordatum then the user defined values will bedisregarded and the relevant preset values used -until you return to the Transformation Parameterswindow and reinstate any preferred parameters.

If a Via datum is enabled, the user transformationparameters are applied after the via transformation.

Note that user supplied values are for a 7 parameterHelmert transformation NOT a Molodenskytransformation. The displayed preset values are for7 parameter Helmert transformations or, where onlydelta X,Y,Z is specified, for a Molodenskytransformation.

Note also that datum transformations are unrelatedto local shift, and that local shift is unrelated todatum transformations. Local shift is an eastingsand northings delta which is applied afterrectangular coordinates have been generated.

Monitor Options

The GPS monitor will, by various means, inform youof the state and quality of the GPS position databeing received from the GPS receiver.

where LA is the latitude (+ve = north, -ve = south)and LO is the longitude (+ve = east, -ve = west).

The WGS84 line has the following values:

9-20


1 - datum is WGS84.0 - datum is not WGS84.-1 - GPS Position Log could not determine whether ornot the datum was WGS84 (see release notes).

For rectangular (projected coordinates):

East=394793.83North=806402.72

where East is the easting, or X value; and North is theNorthing, or Y value.

Also included are the following values:

Date=10/04/01Time=18:21:13GPS=2

The date and time are in "short format" asdetermined by the operating system's locale settingspanel. The GPS item indicates the quality of thesource GPS position and has the following values:

0 - No GPS Position from receiver, GPS Receivercomponent not receiving input, or GPS Receivercomponent not connected.

1 - GPS Position.2 - Differential GPS Position.3 - RTK float GPS Position.4 - RTK fixed GPS position

Note that when GPS=0 then the last known positionis recorded.

File Format - Continuous

The continuous mode adds a line to the log at eachinterval. The fields are similar to ‘LastPosition’mode but appear in a line record format,e.g.

8/21/02 10:05 AM- 57.148463,-2087687,0,2

Which is: date, time, latitude, longitude, WGS84 flag,GPS quality

or

8/21/02 10:05 AM - 394793.83,806402.72,2

Which is easting, northing, GPS quality.

Filter Options

You can set filter options which define the minimumGPS position quality that you will accept. If the filtercriteria are not met then the GPS position is notaccepted by PocketGIS so you will not inadvertentlycapture data from a poor quality position.

If the coordinates are being displayed (see DisplayOptions above) the position is shown in squarebrackets if the filter criteria are not met.

If the filter warning sound is enabled (see MonitorOptions above) a warning sound is played when thefilter criteria are not met.

Normally the current position is calculated from asingle GPS reading. In some circumstances it youmay want to calculate the current position by takingthe average of a number of successive readings. Toenable average position calculation tick the Enableposition averaging box and enter the number ofpoints you wish to be averaged.

Once enabled the current position will be calculatedby averaging the chosen number of points. If youhave enabled the display of geographic coordinatesthen the original geographic coordinate will be thecurrent reading from the GPS receiver and theconverted geographic coordinate will be the averagereading as modified by the datum conversion - ifone is in effect. The number of points that havebeen averaged is shown after the projectedcoordinate as “~n” where n is number of points. Ifthe number of points is less than that specified inthe “Average” options page the coordinate will beshown in square brackets and you will not be able tocapture from GPS.

If you have specified filter criteria in the Filteroptions page then points that do not meet thecriteria will not be included in the averagecalculation.

If a line or area featureis chosen then a single feature will be created withpoints being added to the feature at the choseninterval. The attributes form will not be displayedfor features created by the GPS Capture function but“Auto Set” attribute values will be stored accordingto the definitions setup for the map.

Note that points will not be captured if the GPS filtercriteria are not met at the interval time.

This function is similar to the GPS Trail functionexcept that it works independently of the CaptureTool and the current capture feature, whereas GPSTrail adds points to the current capture feature.

To stop the GPS Capture function select Stop GPSCapture from the devices menu.

High Precision Seed Function

The HP Seed function will send position andstandard deviation information to the receiver froma point which was previously captured from a HPGPS receiver. To use this function an HP receivermust be selected in the ProtocolProtocolProtocolProtocolProtocol item of the GPSConnect dialog. Currently the Omnistar 8300HPreceiver is supported for HP use.

GPS Receiver

This function allows certain values derived from thecurrent GPS position to be inserted into thecurrently selected attribute.

Local Shift

A local shift is an additional adjustment in eastingsand northings which is applied after any datumconversion and once the geographic positionreported by the GPS receiver has been projected intothe chosen coordinate system. Local shift can beused to compensate for differences between GPSgenerated coordinates and base mapping for aparticular area. A local shift consists of a number ofpoints which contain “Original” and “Actual”coordinates for control points that are known toyou. The average difference between the originaland actual coordinates for each point is used tocompute the shift.

If you use local shift then the responsibility forensuring that coordinates are accurate is 100%yours.

By default the Local Shift functionality is disabledand will not appear in PocketGIS menus or controls.To enable Local Shift controls go to the “Local Shift”page of the GPS Receiver Options sheet.

9-38


Tick the Enable local shift controls box. This optionspage also allows you enable or disable theapplication of a local shift and also select the currentlocal shift from any you may have defined. To havethe local shift applied to coordinates generated fromGPS tick the Enable local shift box. To turn off localshift correction untick this box. The Shift popup listallows you to select the current local shift.

If Local shift controls are enabled then a GPS LocalShift sub menu will be present in the Geometry andCapture function menus.

9-39

GPS Receiver

To use a local shift you must first create a local shift,or select an existing one. This can be done from theNew and Select items of the GPS Local Shift menurespectively.

Once you have a current local shift you can use theother functions as follows:

Enable (or Disable ) - turns the application of thecurrent local shift on and off. If a local shift is beingapplied then the delta eastings and delta northingswill be shown in <> brackets in the GPS coordinatedisplay box (providing display of coordinates isenabled).

Add from GPS - adds a point to the current local shift.This option is only available when a position ofacceptable quality is available from the GPS receiver.You will be prompted to select an existing point fromthe map display. The selected point should be thepoint at which you are standing. The GPScoordinate is the original point and the selectedcoordinate is the actual point. Note that anycurrently active local shift is not applied to the GPScoordinate used by this function. A dialog willappear allowing you to see the coordinates and addor cancel the new point.

9-40


Add from Point - adds a point to the current localshift. You will be prompted to select an existingpoint from the map display. The selected point willusually be a control position you previouslycaptured from GPS WITHOUT LOCAL SHIFTENABLED. In this case the selected point is theoriginal point - note this is the opposite of the “Addfrom GPS” function. A dialog will appear allowingyou to enter the actual coordinates of the controlpoint you selected.

Modify - displays the Modify Shift dialog.

9-41

GPS Receiver

This allows you to change the name and storagelocation of the local shift. You can also view each ofthe points in the shift and enable or disable pointsin the shift using the check boxes in the left handcolumn. Double tapping on a coordinate displays adialog allowing you to modify the coordinates of thepoint. The Add button displays a dialog allowingyou to add new points by entering both the originaland actual coordinates. The Delete button will deletethe currently selected point from the shift. The dEast and d North items show the shift valuesincorporating all enabled points.

Delete - deletes the current local shift - you will beasked to confirm, but once you have deleted a shiftit cannot be recovered.

GPS Navigation

GPS Navigation is a simple navigation tool which willgive you a direction and distance from your currentposition to a preselected point.

9-42


To use GPS Navigation you must first establish aconnection to a GPS receiver. You must also ensurethat the correct projection / coordinate system isselected in the GPS Receiver options.

When the GPS Receiver component is installed theGPS Navigation option will appear on the Tools menu.

Select GPS Navigation to display the GPS Navigationwindow.

Enter the coordinates of the position you wish tonavigate to and press Start . A monitor display willappear on the right hand edge of the PocketGIS mapdisplay.

Connecting to a Laser Rangefinder

You can connect various Laser Rangefinders toPocketGIS. You will also need a suitable serialinterface cable which will connect the laser to yourhandheld device.Open the Laser Rangefinder dialogand tap on the Connect Button.

10-11

Laser Rangefinder

The Laser Rangefinder will be connected and thedialog will close.

The Connect Via popup specifies which serial port thereceiver is connected to.

The Laser popup specifies which type of laser youare connecting. Select the option that best describesyour laser.

Once connected the Laser functions will be availableas described in the next section.

You can also connect to the Laser Rangefinder usingthe Connect Laser and Fast Connect Laser functions onthe Attribute, Geometry or Capture function menu.

Connect Laser

This function displays the Laser Rangefinder dialogallowing you to initiate a connection as describedabove.

Fast Connect Laser

This function will try to make an immediateconnection to the laser without showing the dialog.If the port is in use by another PocketGIS peripheral,e.g. a GPS Receiver, that peripheral will be

10-12


disconnected automatically. If the connectioncannot be made then the Laser Rangefinder dialogwill be displayed allowing you to check options andmake the connection.

Disconnecting the Laser Rangefinder

If you wish to disconnect the laser, for example ifyou need to use the serial port for another purpose,reopen the Laser Rangefinder dialog and tap on theDisconnect Button.

You can also select Disconnect Laser from the Devicessub-menu.

Laser Functions

Once a connection has been made with a laserrangefinder a number of functions are available viathe function menu’s of the Geometry and Capturetools.

10-13

Laser Rangefinder

Some laser functions operate via a number of steps.You can restart a function at any time by re-selectingit from the function menu. The current function isindicated with a tick in the menu. You can stop afunction by selecting Cancel Function from the menu,or by selecting another function. You can repeat astep by selecting Undo from the function menu.

Laser Control Point

A key concept of the laser functions is the controlpoint. This provides the point of reference fromwhich a laser shot is interpreted. Many laserfunctions are not available until the control point isestablished. Once established the control point isdisplayed on screen with a cross:

Other Symbols

Other symbols that can appear when using the laserfunctions are as follows.

The circle with a diagonal cross highlights the lastdigitised point when capturing features in theCapture Tool. When modifying existing features inthe Geometry Tool this symbol denotes the “currentpoint” (See Chapter 4).

10-14


The circle with a square cross highlights a vertexthat has been selected as part of a laser function.

Laser Mode

The laser mode controls the interpretation of thelaser shot and the behaviour of some functions. Themode determines:

• Whether to take a fore shot or a back shot.

• Whether the shot is part of a traverse (i.e.tracking from one position to another) or a sideshot (i.e. a one off shot).

Fore / Back Shot Mode

In fore shot mode the distance and bearing of a lasershot are interpreted as starting from the controlpoint and projecting forward.

In back shot mode the distance and bearing of alaser shot are interpreted as starting from apreviously unknown position and projecting back tothe control point.

In short: in fore shot mode you stand at the controlpoint and shoot at something else; in back shotmode you stand somewhere else and shoot at thecontrol point.

You can change the fore / back mode using themenu:

10-15

Laser Rangefinder

The dot indicates the current mode.

Alternatively you can use the F and B buttons on theLaser Bar if it has been enabled.

The current mode is indicated by the depressedbutton.

Side Shot / Traverse Mode

In side shot mode a laser function will take a singlelaser shot, perform it’s function, and then finish.The laser control point will not be changed.

In traverse mode a laser function will iterate - it willtake a laser shot, move the control point to the newposition implied by the shot, and then wait to takeanother shot and repeat the process.

In short: use side shot mode to take a one off shot;use traverse mode to take a sequence of shotsmoving from one point to the next.

You can change the side shot / traverse mode usingthe menu:

10-16


The dot indicates the current mode.

Alternatively you can use the S and T buttons on theLaser Bar if it has been enabled.

The current mode is indicated by the depressedbutton.

Laser Buffer

Laser shots are stored in a buffer prior to being usedby laser functions. This means you can take severalshots with the laser without having to interact withPocketGIS. You can then turn to PocketGIS and usethe laser functions to process the shots in the buffer.This saves you from having to refer back to theapplication on your mobile device after every shot.

The number of shots in the buffer is displayed in theLaser Monitor which was described earlier in thischapter.

Note that in traverse mode the laser buffer is clearedafter each shot is processed. Since you are on themove only one shot at a time will be relevant.

10-17

Laser Rangefinder

Lasers with no Compass

When using a laser which does not have a compass,you will be prompted for the compass bearing withthe following dialog:

Note that this should be a magnetic bearing and thatthe current compass correction factor will be appliedto this value.

Set Control Point Function

The Set Control Point function allows you to definethe current location of the laser control point. Asdescribed earlier in this chapter the control point iskey in working with the laser functions.

To set the control point first select Set Control Pointfrom the current tool’s function menu.


10-18


If a previous control point has already beenestablished then you can move the control pointusing a laser shot. If you are in traverse mode youcan establish the control point by following atraverse line. If there is no current control pointthen you will not be able to use the laser to set thecontrol point.

You can set the control point by tapping on the mapdisplay. If the feature snap option is on, and youtap close to an existing feature, the control point willbe snapped to existing map detail. You can also tapon a target position, the control point is set to thetarget positions coordinate.

If you have a GPS receiver connected, and thecurrent location is available, you can set the controlpoint using GPS.

Bilaterate Control Point Function

The Bilaterate Control Point function allows you todefine the current location of the laser control pointby bilateration from existing map detail.

Note: this function is not affected by the laser modeand so all laser shots are treated as fore shots.

To use this function first select Bilaterate Control Pointfrom the current tool’s function menu.

10-19

Laser Rangefinder


Select the first vertex on the map display andfollowing the

caption, stand at the desired position of the controlpoint and shoot the laser at the feature.

When prompted repeat this procedure for thesecond point.

The selected vertexes will be marked with a circlecross:

When both vertices have been selected and shot atan initial control point position will be marked witha cross

10-20


and the confirm / flip dialog will appear.

Press Confirm if the displayed position is correct, orpress Flip if the displayed position is on the wrongside of the target features. You will now have a newcontrol point.

Note that if you take the laser shots before startingthis function, the shots will be taken automaticallyfrom the buffer and you will not be prompted forthem.

Laser Digitise Function

The Laser Digitise function is used to digitise newpoints using the laser. This function responds to thefore / back and side / traverse modes and can thusbe used to follow a traverse line.

To use this function first select Laser Digitise fromthe current tool’s function menu.

10-21

Laser Rangefinder

Alternatively you can press the laser digitise buttonon the laser bar.

[The Laser Digitise Button is the rightmost as shownabove.]


If you are in fore mode, stand at the control pointand fire the laser at the point to be digitised. If youare in back mode then stand at the point to bedigitised and fire at the control point. A new pointwill be digitised - the effect of this will depend onthe current map tool and the tool mode or capturefeature. If you are in side shot mode the controlpoint will not change. If you are in traverse modethen the control point will move to the location ofthe newly created point.

10-22


Set Control & Digitise Function

This function is a combination of the Set ControlPoint and Laser Digitise functions. You will first beprompted for the control point (which can be set inthe same manner as the Set Control Point function)and following that you will be prompted for a lasershot which will digitise a point as described above.

This function is most useful when the laser mode isset to back shot and traverse. It can then be used todigitise a linear feature by taking offsets from knownfeatures or target positions.

The following example shows a situation where threetarget points have been established. The lasersoftware is set for back shot and traverse shots as wewill be following a line using back shots to referencepoints.

Selecting Set Control & Digitise from the currenttool’s function menu. Gives us the following prompt.

We tap on the first target to establish that as thecontrol point. The control point cross appears andthe prompt changes to ask use to take a shot at thetarget.

10-23

Laser Rangefinder

The point is digitised and the laser control point ismoved to the new position. The display at this pointshows the control point cross and the last digitisedpoint cross superimposed. The prompt changes toask us for the next control point.

We tap on the second target, the control point crossmoves and the prompt changes to ask for the lasershot.

10-24


Having taken the shot, as before, the point isdigitised and the laser control point is moved to thenew position. The prompt changes to ask us for thenext control point.

If we repeat the set control and laser shot process forthe third target we complete our line.

We can then stop the function by selecting CancelFunction from the menu, or by selecting anotherfunction.

Create Target Function

The Laser Rangefinder component has the ability tomaintain one or more temporary target positions.These can be used to mark the position of reflectorsor other temporary reference points for use in laser

10-25

Laser Rangefinder

survey operations. These positions are notpermanently saved to the PocketGIS database andwill be discarded (eventually) once the laserconnection has closed.

To use this function first select Create Target from thecurrent tool’s function menu.


If a control point has already been established thenyou can create the target using a laser shot. If youare in traverse mode you can create a sequence oftargets by following a traverse line. If there is nocurrent control point then you will not be able touse the laser to create a target.

You can create a target by tapping on the mapdisplay.

If you have a GPS receiver connected, and thecurrent location is available, you can create thetarget using GPS.

10-26


Targets are marked with the following symbol:

To make use of a target set the laser control point tothe target position. You can use the Set ControlPoint or Set Control & Digitise functions to do this.Tapping close to the target will cause the controlpoint to snap to the target coordinate.

Enter Target Function

The Enter Target function allows you to create atarget by typing a coordinate position.

To use this function first select Enter Target from thecurrent tool’s function menu.

When the Enter Position dialog appears type in thecoordinate and press enter.

Azimuth Correction Function

The Azimuth Correction function allows you tocompute the compass correction factor by takingshots to known map features. This correction factoris described earlier in this chapter and provides themeans to correct between magnetic and grid north.This function is only available if you are using alaser with a compass.

Before using this function you should establish thecurrent control point as described previously. Alllaser shots should be taken from that control point.

Note: this function is not affected by the laser modeand so all laser shots are treated as fore shots.

To use this function first select Azimuth Correctionfrom the Other Laser Functions sub-menu of thecurrent tool’s function menu.

10-29

The first is to the mirror to establish an accuratedistance.

The second is toward the actual point. This distanceis taken from the first (mirror) shot and the bearingtaken from the second (point) shot.

Measureline Offset Function

This allows you to digitise a point offset from ameasureline.

This function does not use a measuring device but isincluded here so temporary targets can be used torepresent the start and end of the measureline.

10-35

Laser Rangefinder

To use this function select Measureline Offset fromthe Other Laser Functions sub-menu of the currenttool’s function menu.

This function asks you to select the start and endpoints of the measureline, these can be map featuresor temporary targets.

You will be prompted for the length, from the firstpoint, towards the second point, where the offsetbegins. You will also be asked for the offset distance.A point is digitised, at the offset distance, to the“right” of the measureline - the offset isperpendicular to the measureline. If you want theoffset to be to the “left” then enter a negative offset.

Bilaterate and Digitise

This function prompts you to take two shots at apoint from different locations - a new position isthen added to the current feature or a point created.

This function prompts you to stand at a point andtake two shots at other known points - a newposition is then added to the current feature or apoint created.

Insert Measurement Function

The Insert Measurement function is available fromthe Attributes Form function menu.

To insert a measurement from a laser shot firstcomplete the operation with the laser so the shot isin the buffer. In the attributes form select theattribute field which is to receive the value and thenchoose Insert Measurement from the AttributesFunction Menu.

10-37

Laser Rangefinder

A sub-menu containing the values from the first shotin the buffer will appear - choose the one you wantto insert into the attribute. Where a measurementhas more than one value you can insert the variousitems into different attributes by selecting theattribute and then Insert Measurement .

For shots which consist of only one value (e.g.Height) selecting the value into an attribute willclear the shot from the buffer. The next time youbring up the Insert Measurement menu the next shotwill be displayed (if any). Shots which consist ofseveral values are not cleared automatically. Toclear a shot select Discard First Shot from the OtherLaser Functions sub-menu.

Working with Total Stations

This component can be used with Total Stations aswell as “Laser Rangefinders”. If you connect to aTotal Station then the operation of the LaserRangefinder component is slightly different.

Note that the “Set Control and Digitise” function isnot available when connected to a Total Station.

10-38


In order to digitise using a Total Station the ControlPoint needs to be set and, following that, at least onereference shot to a known coordinate is required toallow the software to calculate grid bearings. If youset the Control Point using the “Bilaterate ControlPoint” function then both the station position(Control point) and the relationship to grid bearingsis established. If you set the Control Point byentering a coordinate, from GPS, or by making a shotto the new position then you will need to makeanother shot to a known coordinate (map feature ortarget) using the “Alignment Shot” function.

The “Alignment Shot” function asks you to select apoint and then make a shot to it - you can then usethe “Laser Digitise” function to capture data.

It is expected that you will make use of thetemporary target functionality when working withtotal stations. The “Enter Target” function allowsyou to create targets by typing in a coordinate. Usetargets to represent mirrors. Most functions willwork with targets or map feature points.

10-39

Laser Rangefinder

Using the software in “traverse mode” requires anextra step when working with total stations. Eachtime you move the station to the forward point inthe traverse you will need to make an alignmentshot to the previous (or other known) point beforemaking the next traverse shot.

Bar Code Scanner

Bar Code Scanner

The Bar Code Scanner component provides thecapability for PocketGIS to connect directly to a BarCode Scanner. Functions are available from thefunction menu of the Attributes Form.

A Bar Code ScannerBar Code ScannerBar Code ScannerBar Code ScannerBar Code Scanner item appears on thePocketGIS Tools menu. This allows you to turn theavailability of bar code functions on and off. IfEnable Scanner FunctionsEnable Scanner FunctionsEnable Scanner FunctionsEnable Scanner FunctionsEnable Scanner Functions is ticked then the barcode functions will be available from the AttributesForm's function menu. The Scanner Scanner Scanner Scanner Scanner item allowsyou to select which device to use for bar codescanning. The Connect ViaConnect ViaConnect ViaConnect ViaConnect Via item allows you tochoose how to connect to the scanner - for somescanners there will not be a choice of connectionmethods and you will not be able to change thisitem.

A number of functions are provided on theAttributes Form's function menu. To use thefunctions you must first select the text attribute youwant the function to operate on.

A ScanScanScanScanScan button also appears on the Find by Attributewindow allowing you to scan a bar code into thesearch value field.

Husky fex21

The software will work with the built in bar codescanner on special versions of the Husky fex21Handheld PC, or a ScanTeam scanner attached to theserial port of a Husky fex21 Handheld PC. Thiscomponent will install, and be available, on anyHusky fex21 machine but the “Husky Bar CodeScanner” option will only function if the machinehas a built in bar code scanner. The ScanTeamscanner must be set to use it’s default configurationin order to work with this software - this includesserial port settings and output data format.

Socket Bar Code Scanners

All Socket Bar Code scanners are supported. You willneed to install the software that comes with theSocket scanners before you can use the scannerswith PocketGIS.
