DESCRIPTION

A further iteration of the talk given in Trinidad and Finland. This one goes in to creation of geospatial information in addition to the sharing.

TRANSCRIPT

  • 1. Towards theOpen Geospatial Web Chris Holmes

2. Architectures of Participation Coined by Tim OReilly 3. 4. An Architecture of Participation is bothsocialandtechnical , leveraging the skills and energy ofusersas much as possibletocooperatein building something bigger than any single person or organization could alone . 5. Architectures of Participation Software: The first domain to see benefits The process can be applied to other fields 6. Geospatial Data

    • CreationSharing

7. 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 8. The Success of SDIs? 9.

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

10. Contribute to Compelling Initiative.

  • Mandated law != useful
  • Few real users
  • No recognition
  • No reward for the effort
  • Try again in five years?

vs. 11.

  • Quickly add data to quality map
  • Ease of customization
  • Recognition: Shared, emailed, blogged about
  • Indexed & Searchable

Contribute to Compelling Initiative 12.

  • Consumers Producers
  • Data from official sources
  • Metadata takes training
  • GIS Professionals Only

Users asContributors 13. Users asContributors

  • Consumers = Producers
  • Everyone encouraged to contribute
  • Community members grow in to experts
  • Even used for real GISits easier than getting on an SDI

Maps 14. SDI Contributing: Data 15. Hardware 16. Software 17. Metadata 18. Metadata Training 19. A Catalog to Register On 20. Contributing Data to Google 21. 22. Barriers to Entry

  • Browser
  • Metadata
  • Training
  • Server Hardware
  • WMS Software
  • Sharing Agreements
  • Catalog Registration

23. Does user contribution alone make an SDI? 24. Let commercial players run SDI?

  • SDIs 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!

25. Towards the Open Geo Web

  • Inclusive Infrastructure
  • Single Geo Web Project
  • Unlimited Potential
  • Build on existing Architectures
  • of Participation

26. Principles:Towards the Open Geo Web

  • Not just policies,
  • requirements & mandates
  • Align incentives to create
  • a single Geospatial Web

27. Geospatial Data

    • CreationSharing

28. OpenStreetMap

    • Geo Data Creation:
  • Is already here

MapShare 29. OSM Maps 30. OSM Maps 31. Though far from mature

  • Licensing is a big problem
  • Tools are unsophisticated
  • Few different workflow options
  • But huge potential has been proven

32. Towards Maturity:Workflow vs 33. Towards Maturity:Scopevs 34. 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

35. Towards Maturity:LicensingForGeodata? 36. 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 - authoritativeandalways up to date

37. 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

38. 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

39.

    • Build on other Architectures of Participation
  • Dont go it alone

MapShare Align their success with yours 40. 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

41. No more Aquariums! 42. Join the Web! 43. A Geo Web Node 44. GeoWeb Node:Rooted in Data Access PostGIS Oracle Spatial DB2 ArcSDE MySQL 45. GeoWeb Node:Spreading to the Geo Web Google Earth Virtual Earth Google Maps NASA WorldWind Yahoo!Maps 46. GeoWeb Node:Integrated Viewer 47. GeoWeb Node:Online Styling 48. GeoWeb Node:Easy upload Choose File Geofile.shp Upload 49. GeoWeb Node:Searchable by Google 50. GeoWeb Node:Editing 51. GeoWeb Node:Versioning and advanced workflow 52. GeoWeb Node:User accounts

  • User statistics
  • Comments, ratings, tags
  • Collaborative Filtering
  • Rankings of best views and data sets contributed
  • Highest rated, most viewed, most shared

53. GeoWeb Node:Metadata

  • Derive from user actions
  • Dont require metadata to put out data
  • Wiki type editing of metadata
  • Automatically available with the Catalog standards

54. 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 GeoWeb nodes to be truly useful

55. Proprietary vs.Open Source Nodes

  • Implementation of standards is the most important
  • Open Source has advantages
    • Keep vendors honest with standards
    • Technical innovation by all
    • Increasing returns on investment

56. Open vs Closed Geo Data

  • Most important thing is that data is accessible in all standard formats
  • But the Geo Web will be built on Open Data
    • Google has proven this
    • An open base will lead to more contributions on top

57. Official vs. User-contributed Data

  • One Infrastructure
  • Limited User Permissions
  • Optional Commenting & Rating

58.

  • The future is users
  • Geo Participation
    • GIS Professionals
    • Amateur Neo Geographers
    • Anyone with a locative device
  • Technology & Community

The Future: Beyond Portals 59. My GeoWeb Goal Lets build a Geo Web thatssocompellingandeasy-to-usethat everyone: Citizens, Governments, NGOs and Companies all naturally collaborate towards the same infrastructure for public good. 60. What you can do:

  • Go beyond portals, build National Geo Web Nodes with free hosting for open contributors
  • Try opening data in open source / share alike and/or non-commercial ways, align incentives back
  • Look for new business further up the value chain, just selling data may not last
  • Partner with companies who are correcting data and moving up the value chain, dont go it alone
  • Experiment with participation, both internally and externally
