Geoforum: Digimap Update 2015
New and Enhanced features coming to Geo and Digimap Services
Guy McGarva
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.
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
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
Working On…
• Refresh of Digimap Home page• Tablet friendly Digimap• New Historic Downloader• New HydroView Roam (Raster Charts)• Geology Roam/Marine Roam data updates• Additional site rep stats (all collections)• New version of Help system in HTML5• Ancient Roam – add current data to 2-up view• Improved OS and Geology cartography
• Some examples..
Geology Roam – coming soon
• Additional basemaps• Sorting of legend by age• Additional products (10K, 25K)
Refresh Digimap Home Page
- Responsive- No login popup- Highlight events- Simpler navigation- Follow JISC guidelines- Accessible- Something like this but not this!
New MasterMap Cartography
Existing
New
- Existing style will still be available as a Basemap
New OS data recently added
PointX [points of interest] OS MasterMap ITN - Urban Paths Theme
OS MasterMap Sites Layer OS Terrain 5
Future developments
• Outline/plan version OS MasterMap in DWG format
• 3D buildings in DWG format
• OS Terrain 5 and 50 contours in DWG format
Building Height Attribute data (BHA)
• Released by OS in March 2014• Enhancement to Topography
layer• Covers around 10,000 km2 of
major towns and cities in GB - see where:– http://bit.ly/1zvKI9q
• Alpha release – no guarantee error free
• In future will be included in Topography layer
• CSV, KML or File Geodatabase formats
• EDINA supplies as 5x5km grid tiles
New Service: Digimap for Colleges
Launched last year
GoGeo Mobile App
• The GoGeo mobile App has been developed
Fieldtrip GB/ Fieldtrip Open
• An Edina based alternative to Dropbox as storage provider• Multi-page complex forms with dependencies• Thumbnail images in selection lists (e.g. showing examples of butterfly
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
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.
Help & Support
• New online Chat facility• Q & A Forum
Responsive help pages
Resource Centre
Updates to the Resource Centre- New GIS/CAD
resources section
Training - Webinars
Past
Planned
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
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
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
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
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
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.
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:
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
Load Data in ArcGIS Pro
Add data…
(same as in ArcGIS)
Convert to 3D
Convert map to 3D
(on the View tab)
Then drag vector layers to the 3D Layer
Extrude to 3D
1. Set the Ground
Extrude the building to Max Height using attribute [relhmax]
Add Backdrop Data
Using VML Raster data from Digimap
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
Add Representation
Can do simple solid colours or use more complicated ‘Procedural Symbols’
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”
Add Trees and POI
Add “Realistic Trees” for tree features from OS MasterMap and 3D Symbols for features from PointX POI
Add Imagery background
Using Esri Imagery Basemap
Also set background colour for sky and Illumination for shading
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
Other GIS are available and will do similar jobs
