1. Towards the Open Geospatial Web: Architectures of Participation, Bottom up SDI’s and GeoNodes –Chris Holmes

2. Geospatial is Everywhere

3. “…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.” Spatial Data Infrastructure (SDI) – Groot & McLaughlin 2000

4. The Success of SDIs?

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

7. 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.

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

9. Geospatial Data Creation Sharing

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

11. Compelling Initiative: ‘give a win’ No benefit to registering Few real users No recognition No reward for the effort Uses stick, not carrot vs.

12. Quickly add data to quality map Ease of customization Recognition: Shared, emailed, blogged about… Indexed & Searchable Compelling Initiative: ‘give a win’

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

14. Maps 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

15. SDI Contributing: Data

16. Hardware

17. Software

18. Metadata

19. Metadata Training

20. A Catalog to Register On

21. Contributing Data to Google…

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

24. Does user contribution alone make an SDI?

25. 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!

26. Towards the Open Geo Web Inclusive Infrastructure Single “Geo Web” Project True data accessibility Build on existing Architectures of Participation

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

28. Geospatial Data Creation Sharing

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

30. OSM Maps

31. OSM

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

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

34. No more Aquariums!

35. Join the Web!

36. A GeoNode Building SDI’s from the bottom up

37. A GeoNode: The OpenGeo Suite Building SDI’s from the bottom up

38. GeoNode: Rooted in Data Access PostGIS Oracle Spatial DB2 ArcSDE MySQL

39. GeoNode: Spreading to the Geo Web Google Earth Virtual Earth Google Maps NASA WorldWind Yahoo! Maps

40. GeoNode: Integrated Viewer

41. GeoNode: Online Styling

42. GeoNode: Easy upload Choose FileGeofile.shp Upload

43. GeoNode: Searchable by Google

44. GeoNode: Editing

45. GeoNode: Mobile access and editing http://iol.opengeo.org/ examples/draw.html On your iphone

46. GeoNode: User accounts User statistics Comments, ratings, tags Collaborative Filtering Rankings of best ‘views’ and data sets contributed Highest rated, most viewed, most shared

47. GeoNode: Metadata Derive from data and user actions Don’t require metadata to put out data Wiki type editing of metadata Automatically available with the Catalog standards

48. GeoNode: The bottom up SDI Traditional SDI start with metadata Metadata -> Users -> Data GeoNodes start with data Data -> Users -> Metadata Align incentives so everyone gets some benefit from contributing Make it easy and open for anyone to use, not just specialists Build iteratively

49. Where to put these nodes? Everywhere! Anywhere you might put a portal Anywhere you have an ‘Enterprise GIS System’ Anywhere people share data with each other Handling all these use cases will evolve GeoNodes to be truly useful

50. The CAPRA GeoNode Project for the World Bank to build many of these ideas First goal is compelling portal to make risk and hazard maps available Integrated Viewer, multiple download options, ability to compose and save maps, 3D view Built on the OpenGeo Suite, and extending its capabilities for user contributions and ease of use.

51. GeoNode Home View

52. GeoNode Data View

53. GeoNode Map View

54. GeoNode User View

55. CAPRA GeoNode: Future Directions Custom apps with Geoprocessing Crowd Sourced Editing Offline/low bandwidth syncing Integration with GeoNetwork OS Collaborative Filtering Federated Search

56. My GeoWeb Goal Let’s build a Geo Web that’s so compelling and easy-to-use that everyone: Citizens, Governments, NGO’s and Companies all naturally collaborate towards the same infrastructure for public good.

57. Spreading the GeoNodes Build the first GeoNodes on Open Source Software Allow anyone to use the same package Other domains and regions will improve software in other ways that all nodes can use Encourage internal use, make it the easiest way to create and share data Sync nodes up and down for increased performance Result is a true information infrastructure

58. The future is users Geo Participation GIS Professionals Amateur Neo Geographers Anyone with a locative device Technology & Community The Future: Beyond Portals
