Quality Improvements

• We’ve listened to what you have wanted through surveys, support requests, discussions etc..

See Quality Improvement Plans at http://edina.ac.uk/impact/ for details of what

has been requested and what we are doing.• We have also made a lot of improvements to

back-end systems to make the website faster, more reliable and resilient e.g. load balancing and new versions of software.

Page 3: Geoforum - Digimap Update 2015

Last year (2014-2015)

• Main achievements– New registration system– Lots more data added to the services (OS, Geology)– New OS licence finally signed– More formats e.g. BHA in File Geodatabase, MM

Topo in FGDB and DWG– Dudley Stamp data added to Historic Collection– Marine Downloader created – Support: Chats, Webinars, Help pages, Q & A– Digimap for Colleges launched

Page 4: Geoforum - Digimap Update 2015

Also completed…Other Geo services

• UK Data Service Census Support – became ‘Open’ - no login necessary to download data

• Enhancements to Unlock, including adding historic English place-names (DEEP) and improvements to the API

• GoGeo – adding language conversion, a mobile app, support for Gemini 2.2. and updating GeoDoc resources

species)• Ability to upload existing POI’s• Ability to upload map overlays• Updated base maps (using new OS vector data) • Fieldtrip Open – Open Street Map data for use outside UK

Page 16: Geoforum - Digimap Update 2015

Geo Projects

• COBWEB Creating a testbed environment to enable citizens living within UNESCO designated Biosphere Reserves to collect environmental data using mobile devices

• Palimpsest, January 2014 – April 2015Providing access to vivid, evocative and dramatic excerpts of a wide range of geolocated Edinburgh-based literary texts either via the web resource, or in the city streets via a smartphone or tablet.

• Spatial Memories, February – August 2014Enabling people with disabilities to become more independent and less reliant on others in making spatially aware reminders, hints and checklists using a smartphone app.

Page 17: Geoforum - Digimap Update 2015

Help & Support

• New online Chat facility• Q & A Forum

Page 18: Geoforum - Digimap Update 2015

Responsive help pages

Page 19: Geoforum - Digimap Update 2015

Resource Centre

Updates to the Resource Centre- New GIS/CAD

resources section

Page 20: Geoforum - Digimap Update 2015

Training - Webinars

Past

Planned

Page 21: Geoforum - Digimap Update 2015

Longer term aims

• Integrate Geo services together more• Make more use of available web data feeds• Make user workflows simpler and more

complete• Provide solutions to common problems to

do with the data life cycle• Increase utility and value of services• Improve support resources and capabilities

Page 22: Geoforum - Digimap Update 2015

What do you want to see?

• Data• Functionality• Support

Using BHA data from Digimap in ArcGIS Pro

A case study in using BHA data from Digimap in ArcGIS Pro

Page 24: Geoforum - Digimap Update 2015

What are BHA?

• BHA are Building Height Attributes from Ordnance Survey

• Released as Alpha product in 2014• Provide multiple values for heights

of buildings (both absolute and relative)

• Covers most major cities and towns (but not all)

• Supplied by Ordnance Survey as 5km tiles in CSV format

• Linked to OS MasterMap Topography Layer (i.e. building footprints) by TOID

Page 25: Geoforum - Digimap Update 2015

Using BHA CSV and OS MasterMap

To start with we created a version of the BHA CSV with a modified TOID that could be joined more easily

Need to Join the data on TOID

Page 26: Geoforum - Digimap Update 2015

Using data from OS directly

However…- Lot of steps- Slow when dealing with large datasets- Needed to use a schema.ini file to load the CSV correctly- Required ArcGlobe or ArcScene to visualise the 3D buildings

Help

Page 27: Geoforum - Digimap Update 2015

So what have we done?

So, to make is easier to use we have:- Created a File Geodatabase version using

FME that contains the Building geometries from OS MasterMap Topography Layer combined with the BHA data.

- Used ArcGIS Pro to visualise the data.

Page 28: Geoforum - Digimap Update 2015

Using File Geodatabase BHA in ArcGIS Pro

• Download BHA File Geodatabase from Digimap• Open BHA File Geodatabase• Convert map to 3D• Extrude buildings

• More advanced steps– Add background data– Add in more detailed Terrain 5 data– Set up symbology and representation– Add in other vector data (e.g. Trees, POI)

Now the steps are:

Page 29: Geoforum - Digimap Update 2015

First step is to download all the data

For Example:- Building Height

Attributes- MM Topography

Layer- OS Terrain 5 DTM- VectorMap Local

Raster- PointX POI

Download in File Geodatbase, Shape or other suitable format

Page 30: Geoforum - Digimap Update 2015

Load Data in ArcGIS Pro

Add data…

(same as in ArcGIS)

Page 31: Geoforum - Digimap Update 2015

Convert to 3D

Convert map to 3D

(on the View tab)

Then drag vector layers to the 3D Layer

Page 32: Geoforum - Digimap Update 2015

Extrude to 3D

1. Set the Ground

Extrude the building to Max Height using attribute [relhmax]

Page 33: Geoforum - Digimap Update 2015

Add Backdrop Data

Using VML Raster data from Digimap

Page 34: Geoforum - Digimap Update 2015

Add More Detailed Terrain• By default ArcGIS Pro will use a global terrain

dataset• To use more accurate terrain, download the

OS Terrain 5 dataset from Digimap• Add Preset Ground• Select downloaded .ASC files

Page 35: Geoforum - Digimap Update 2015

Add Representation

Can do simple solid colours or use more complicated ‘Procedural Symbols’

Page 36: Geoforum - Digimap Update 2015

Use Procedural Rules

Can either use ones that come with ArcGIS Pro or import ones from City Engine

• Using built in “International Building” Procedural Rule

• Set [TotalHeight] to be calculated from the [relhmax] attribute

• Building type set to “Office”

Page 37: Geoforum - Digimap Update 2015

Add Trees and POI

Add “Realistic Trees” for tree features from OS MasterMap and 3D Symbols for features from PointX POI

Page 38: Geoforum - Digimap Update 2015

Add Imagery background

Using Esri Imagery Basemap

Also set background colour for sky and Illumination for shading

Page 39: Geoforum - Digimap Update 2015

Caution!

• Remember projections!• If you overlay OS data on one of the Esri

Basemaps you must use a Transformation (preferably OSTN02)

• In ArcGIS Pro this is done by selecting the Properties of the Map and then Transformation

The Final Result
