  • Towards an Open Geo Web: Linking Open Source’s Architectures of Participation to the Global SDI Initiative
  • Towards the Open Geospatial Web

    1. 1. Towards the Open Geospatial Web – Chris Holmes
    2. 2. “ Architectures of Participation” – Coined by Tim O’Reilly
    3. 4. 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. 5. Architectures of Participation Software: The first domain to see benefits The process can be applied to other fields
    5. 6. Geospatial Data <ul><ul><li>Creation Sharing </li></ul></ul>
    6. 7. OpenStreetMaps++ <ul><ul><li>Geo Data Creation… </li></ul></ul><ul><li>Crowd sourced creation and maintenance of GIS layers </li></ul><ul><li>Towards cooperation between Citizens, Governments, NGOs and Companies </li></ul>
    7. 8. 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.” <ul><ul><li>Geo Data Sharing… </li></ul></ul>– Groot & McLaughlin 2000
    8. 9. The Success of SDIs?
    9. 10. <ul><ul><li>Compelling Initiative </li></ul></ul><ul><ul><li>User at the Center </li></ul></ul><ul><ul><li>User Responsibility </li></ul></ul><ul><ul><li>No Barriers or Difficulty </li></ul></ul><ul><ul><li>Factors for Success </li></ul></ul>
    10. 11. Contribute to Compelling Initiative. <ul><li>Mandated law != useful </li></ul><ul><li>Few real users </li></ul><ul><li>No recognition </li></ul><ul><li>No reward for the effort </li></ul><ul><li>Try again in five years? </li></ul>vs.
    11. 12. <ul><li>Quickly add data to quality map </li></ul><ul><li>Ease of customization </li></ul><ul><li>Recognition: Shared, emailed, blogged about… </li></ul><ul><li>Indexed & Searchable </li></ul>Contribute to Compelling Initiative
    12. 13. <ul><li>Consumers ≠ Producers </li></ul><ul><li>Data from “official” sources </li></ul><ul><li>Metadata takes training </li></ul><ul><li>GIS Professionals Only </li></ul>Users as Contributors
    13. 14. Users as Contributors <ul><li>Consumers = Producers </li></ul><ul><li>Everyone encouraged to contribute </li></ul><ul><li>Community members grow in to experts </li></ul><ul><li>Even used for ‘real GIS’ …it’s easier than INSPIRE </li></ul>Maps
    14. 15. SDI Contributing: Data
    15. 16. Hardware
    16. 17. Software
    17. 18. Metadata
    18. 19. Metadata Training
    19. 20. A Catalog to Register On
    20. 21. Contributing Data to Google…
    21. 23. Barriers to Entry… <ul><li>Browser </li></ul><ul><li>Metadata </li></ul><ul><li>Training </li></ul><ul><li>Server Hardware </li></ul><ul><li>WMS Software </li></ul><ul><li>Sharing Agreements </li></ul><ul><li>Catalog Registration </li></ul>
    22. 24. Does user contribution alone make an SDI?
    23. 25. Let commercial players run SDI? <ul><li>SDI’s are a public good </li></ul><ul><li>Commercial players have profit motive </li></ul><ul><li>Commercial players seek monopoly </li></ul><ul><li>DANGER: Governments are handing over data </li></ul><ul><li>without opening it to anyone else! </li></ul>
    24. 26. Towards the Open Geo Web <ul><li>Inclusive Infrastructure </li></ul><ul><li>Single “Geo Web” Project </li></ul><ul><li>Unlimited Potential </li></ul><ul><li>Build on existing Architectures </li></ul><ul><li>of Participation </li></ul>
    25. 27. Principles: Towards the Open Geo Web <ul><li>Not just policies, </li></ul><ul><li>requirements & mandates </li></ul><ul><li>Align incentives to create </li></ul><ul><li>a single Geospatial Web </li></ul>
    26. 28. GIS Professionals: MIA? <ul><li>Current Geo Web of Microsoft and Google is focused on consumer applications </li></ul><ul><li>Powered by GIS Pros, but in a black box </li></ul><ul><li>GIS pros should be at the center of the Open Geo Web </li></ul><ul><li>Align incentives to make it much easier for experts to participate </li></ul>
    27. 29. <ul><ul><li>Compelling Initiative? </li></ul></ul><ul><ul><li>User at the Center? </li></ul></ul><ul><ul><li>User Responsibility? </li></ul></ul><ul><ul><li>No Barriers or Difficulty? </li></ul></ul><ul><ul><li>Geo Web for GIS Pros? </li></ul></ul>
    28. 30. Put GIS Pros back at the center Unite the worlds of the GIS Professional and the amateur ‘Neo Geographer’ so all can cooperate to build something bigger than either group could alone.
    29. 31. NeoGeo and GIS Cooperation <ul><li>Identify and correct mistakes </li></ul><ul><li>More creative visualizations </li></ul><ul><li>Finding and evaluating data </li></ul><ul><li>Living data, constantly evolving </li></ul>
    30. 32. Aligning Incentives <ul><li>Goal is Pro and Amateur working on the same infrastucture, with compatible tools </li></ul><ul><li>Each doing what they already do, but naturally benefitting one another </li></ul><ul><li>Give each compelling reason to contribute to shared infrastructure </li></ul><ul><li>Must satisfy all that current tools do, and go beyond </li></ul>
    31. 33. Beyond Portals <ul><li>Web Portals went out of fashion in 2001 </li></ul><ul><li>‘ GeoWeb Node’ = GeoPortal 2.0 </li></ul><ul><li>GeoPortal goal: find existing data </li></ul><ul><li>GeoWeb Node goal: increase creation and sharing of data </li></ul><ul><li>End goal of both is easier to find and use data </li></ul>
    32. 34. No more Aquariums!
    33. 35. Join the Web!
    34. 36. A Geo Web Node
    35. 37. GeoServer Evolution <ul><li>Started with the Data, first sharing, then creation </li></ul><ul><li>Working on the User, and their maps </li></ul><ul><li>Metadata will evolve out of Data and User </li></ul><ul><li>GeoPortal: Metadata -> User -> Data </li></ul><ul><li>GeoWeb Node: Data -> User -> Metadata </li></ul>
    36. 38. GeoServer Data: Rooted in Data Access PostGIS Oracle Spatial DB2 ArcSDE MySQL
    37. 39. GeoServer Data: Spreading to the Geo Web Google Earth Virtual Earth Google Maps NASA WorldWind Yahoo! Maps

    41. 43. GeoServer Data: Editing
    42. 44. GeoServer Data: Versioning
    43. 45. GeoServer User: Easy upload Choose File Geofile.shp Upload
    44. 46. GeoServer User: Online Styling
    45. 47. GeoServer User: Map collaboration <ul><li>Create a ‘view’ of existing data on a node </li></ul><ul><li>Annotate it spatially </li></ul><ul><li>Add in remote data, from other nodes </li></ul><ul><li>Restyle and annotate another user’s view </li></ul><ul><li>Set permissions for other users to contribute to your data </li></ul><ul><li>Easy ‘embeds’, share your map on blog or webpage, on Google Maps or Google Earth </li></ul>
    46. 48. GeoServer User: User accounts <ul><li>User statistics </li></ul><ul><li>Comments, ratings, tags </li></ul><ul><li>Collaborative Filtering </li></ul><ul><li>Rankings of best ‘views’ and data sets contributed </li></ul><ul><li>Highest rated, most viewed, most shared </li></ul>
    47. 49. GeoServer Metadata: Data about the data <ul><li>Derive from user actions </li></ul><ul><li>Don’t require metadata to put out data </li></ul><ul><li>Wiki type editing of metadata </li></ul><ul><li>Automatically available with the Catalog standards </li></ul>
    48. 50. Where to put these nodes? <ul><li>Everywhere! </li></ul><ul><li>Anywhere you might put a portal </li></ul><ul><li>Anywhere you have an ‘Enterprise GIS System’ </li></ul><ul><li>Anywhere people share data with each other </li></ul><ul><li>Handling all these use cases will evolve GeoWeb nodes to be truly useful </li></ul>
    49. 51. Proprietary vs. Open Source Nodes <ul><li>Implementation of standards is the most important </li></ul><ul><li>Open Source has advantages </li></ul><ul><ul><li>Keep vendors honest with standards </li></ul></ul><ul><ul><li>Technical innovation by all </li></ul></ul><ul><ul><li>Increasing returns on investment </li></ul></ul>
    50. 52. Open vs Closed Geo Data <ul><li>Most important thing is that data is accessible in all open formats </li></ul><ul><li>But the Geo Web will be built on Open Data </li></ul><ul><ul><li>Google has proven this </li></ul></ul><ul><ul><li>An open base will lead to more contributions on top </li></ul></ul>
    51. 53. Official vs. User-contributed Data <ul><li>One Infrastructure </li></ul><ul><li>Limited User Permissions </li></ul><ul><li>Optional Commenting & Rating </li></ul>
    52. 54. <ul><li>The future is users </li></ul><ul><li>Geo Participation </li></ul><ul><ul><li>GIS Professionals </li></ul></ul><ul><ul><li>Amateur Neo Geographers </li></ul></ul><ul><ul><li>Anyone with a locative device </li></ul></ul><ul><li>Technology & Community </li></ul>The Future: Beyond Portals
    53. 55. 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.
    54. 56. What you can do: <ul><li>Start collaborating with amateurs </li></ul><ul><li>Try to put your data on Google Maps </li></ul><ul><li>Improve Open Street Map </li></ul><ul><li>Experiment with crowd sourcing </li></ul><ul><li>Install software get your data on the Geo Web </li></ul><ul><li>There are many more paths to contribute your professional skills and energy to help in small and big ways </li></ul>
