towards the open geospatial web (eurogeographics edition)
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
