  1. Towards the Open Geospatial Web –Chris Holmes

  2. “Architectures of Participation” – Coined by Tim O’Reilly

  3. An “Architecture of Participation” is both social and technical, leveraging the skills and energy of users as much as possible to cooperate in building something bigger than any single person or organization could alone.

  4. Architectures of Participation Software: The first domain to see benefits The process can be applied to other fields

  5. Geospatial Data • Creation Sharing

  6. Primary Goal“…the sources, systems, network linkages, standards, and institutional issues involved in delivering spatially-related data from many different sources to the widest possible group of potential users at affordable costs.” • Geo Data Sharing… – Groot & McLaughlin 2000

  7. The Success of SDIs?

  8. Factors for Success • Compelling Initiative • User at the Center • User Responsibility • No Barriers or Difficulty

  9. Contribute to Compelling Initiative. • Mandated law != useful • Few real users • No recognition • No reward for the effort • Try again in five years? vs.

  10. Contribute to Compelling Initiative • Quickly add data to quality map • Ease of customization • Recognition: Shared, emailed, blogged about… • Indexed & Searchable

  11. Users as Contributors • Consumers ≠ Producers • Data from “official” sources • Metadata takes training • GIS Professionals Only

  12. Users as Contributors • Consumers = Producers • Everyone encouraged to contribute • Community members grow in to experts • Even used for ‘real GIS’ …it’s easier than getting on an SDI Maps

  13. SDI Contributing: Data

  14. Hardware

  15. Software

  16. Metadata

  17. Metadata Training

  18. A Catalog to Register On

  19. Contributing Data to Google…

  20. Barriers to Entry… Browser Metadata Training Server Hardware WMS Software Sharing Agreements Catalog Registration

  21. Does user contribution alone make an SDI?

  22. Let commercial players run SDI? • SDI’s are a public good • Commercial players have profit motive • Commercial players seek monopoly DANGER: Governments are handing over data without opening it to anyone else!

  23. Towards the Open Geo Web Inclusive Infrastructure Single “Geo Web” Project Unlimited Potential Build on existing Architectures of Participation

  24. Principles: Towards the Open Geo Web Not just policies, requirements & mandates Align incentives to create a single Geospatial Web

  25. Geospatial Data • Creation Sharing

  26. OpenStreetMap • Geo Data Creation: MapShare™ • Is already here…

  27. …Though far from mature • Licensing is a big problem • Tools are unsophisticated • Few different workflow options • But huge potential has been proven

  28. Towards Maturity: Workflow vs

  29. Towards Maturity: Scope vs

  30. Towards Maturity: Tools Compatibility with GIS tools Advanced workflow management Sandboxes, approval before acceptance Automatic validation (topology, required fields) Branches and merging with Conflict Resolution Automatic change notification email / rss Automatic feature extraction: GPS tracks and Satellite images

  31. Towards Maturity: Licensing For Geodata?

  32. Towards Maturity: Cooperation Align efforts so that amateur, commercial, NGO and governmental creators all naturally collaborate Figure out workflows, tools and licenses that work for everyone Put NMCAs at the center, incentivizing updates to core layers (from citizens and companies) Towards living data, constantly evolving - authoritative and always up to date

  33. Towards Maturity: The role of the NMCA Natural leader, the most experience capturing and maintaining the highest quality data Must build upon success of accurate and official maps with latest techniques to improve with participation Look to derive revenue from services around the data Use Open Source Business models as examples

  34. Learning from Open Source Business Hosted Services Geocoding Route finding Custom Tiles Hosting additional layers, etc. Guarantee of accuracy Value add packaging - formats, documentation, software Subscription to latest updates

  35. Build on other Architectures of Participation MapShare™ • Don’t go it alone Align their success with yours

  36. Beyond Portals Web Portals went out of fashion in 2001 ‘GeoWeb Node’ = GeoPortal 2.0 GeoPortal goal: find existing data GeoWeb Node goal: increase creation and sharing of data End goal of both is easier to find and use data

  37. No more Aquariums!

  38. Join the Web!

  39. A Geo Web Node

  40. GeoWeb Node: Rooted in Data Access MySQL PostGIS ArcSDE DB2 Oracle Spatial

  41. GeoWeb Node: Spreading to the Geo Web Google Earth NASAWorldWind Google Maps Virtual Earth Yahoo! Maps

  42. GeoWeb Node: Integrated Viewer

  43. GeoWeb Node: Online Styling

  44. GeoWeb Node: Easy upload Choose File Geofile.shp Upload

  45. GeoWeb Node: Searchable by Google

  46. GeoWeb Node: Editing
