GeoForAll UrbanScience CityAnalytics

Welcome to "Geo for All" Urban Science and City Analytics Thematic

Chairs: Chris Pettit (Australia) and Patrick Hogan (USA)

The mail list will be geoforall-urbanscience@lists.osgeo.org

With the "Geo for All" Urban Science and City Analytics thematic group established, the chairs of this are now the contact points for any new initiatives, ideas in this theme and the mailing list becomes the first point of contact for the new members and all members can use the list for collaborating on building subject specific collaborations.

This way we can make sure it is scalable and meets local/region requirements/needs.All ideas welcome.

These are the 'CitySmart' app categories, feel free to expand (use-cases next): We owe all of this 'first cut' to Brandt Melick, Information Technology Department Director, City of Springfield Oregon USA http://www.nsdinow.org

1. elevation data 2. place names 3. buildings 4. utilities 5. parks 6. wetlands 7. creeks 8. streams 9. rivers 10. habitats for native and invasive species 11. rights of way 12. street systems 13. storm drainage 14. water distribution systems 15. power distribution systems 16. waste water systems 17. parcel information 18. building permits 19. construction zones, etc.

• Data sharing – Municipalities need to be able to share information with site developers, site constraint specialists (environmental scientists, planners and engineers), utility service providers and regulators. The following information is requested on a regular basis for a wide variety of location based solutions, namely (ESRI products, Autodesk products and standard office products such as excel, access, etc.). These data sets most often include, in order of importance:
  • Imagery (3-inch pixel is preferred, 1 foot pixel is less preferred, 1 meter is getting much less preferred)
  • Cadastral Information (parcel polygons, Rights of Way (ROW), property ownership, assessment and taxation information and property class)
  • Address Information (house number, street name, City, zip, site location (coordinates) and zoning information)
  • Jurisdictional boundaries (incorporated areas, city limits, county boundaries, etc.), urban growth boundaries, public safety response areas
  • Elevation Information (DEM’s (raster), DTM’s (vector), contours and spot elevation points, as well as mass points and break lines)
  • Waterways and protected areas (wetlands, fish-bearing streams, endangered species habitat, well-head protection zones, etc.)
  • Facilities a.k.a. utilities (waste-water, storm-water, transportation systems, power, drinking water, etc. who owns the facility, who maintains the facility, etc.)
  • Structures a.k.a. facilities (bridges, building foot prints, complexes, monuments, etc.)
  • Documents (reference material, procedures, regulations, metadata, etc.)
  • Lidar everyone wants yet few understand how to put it to good use (we are spoiled with 8 points per meter, 4-2 points per meter is still of good value)

• Biggest challenges: data simplification, data currency, projection (datum) conversion, unit conversion (metric to standard), storage, firewalls, metadata, and then use once received . . . expertise with highly complex ever changing location based tools typically results in the need for some hand holding, then after being used, how to keep it current . . . (interoperable and open web services)

• Site review – Municipalities need to evaluate the impact of proposed development activity on the existing build and natural environment, which typically includes estimating how much cut and fill is being proposed, how proposed land alteration impacts surface drainage, how proposed structures will to connect to city services (waste-water, storm-water, drinking-water, power, etc.), how steep the roads will be (slope for fire trucks), how close to wetlands and other protected waters of the state. These data sets most often include, in order of importance:
  • Imagery
  • Cadastral
  • Elevation
  • Facilities (structures and utilities)
  • Waterways . . .

Other ideas for a network grant proposal

• Universities and university management are like small towns. Perhaps an educational connection here is to have multiple universities work together on building platforms for managing university infrastructure? -- Charlie Schweik
