Geonode Presentation Transcript

  • 1. Spatial Data Infrastructure (SDI)
  • 2. Spatial Data Infrastructure (SDI) “[Spatial Data Infrastructure] provides a basis for spatial data discovery, evaluation, and application for users and providers within all levels of government, the commercial sector, the non-profit sector, academia and by citizens in general.” – SDI Cookbook
  • 3. The theory of SDI developed before we learned what was possible with the Internet
  • 4. Imagine... ...what an ideal SDI would be like
  • 5. Imagine... ...an SDI that makes uploading, sharing, and working with data as easy as blogging
  • 6. Publishing data Anthony has some spatial data and wants to display it as part of a blog post.
  • 7. Publishing data Anthony uploads it to a public SDI, styles it, provides a background, and then puts a map widget on his blog.
  • 8. Publishing data Meanwhile, the data, style, and map remain available on the public SDI for others to use.
  • 9. Metadata and reputation The World Organization tells Cameron, their consultant, to put data she has gathered on their SDI.
  • 10. Metadata and reputation Other users notice mistakes in the metadata. They notify Cameron and give it a low rating.
  • 11. Metadata and reputation Cameron fixes the mistakes, and the other users rate the data more highly. Her reputation on the SDI improves.
  • 12. Federated search A regional Health agency and a regional Transit agency have separate SDI systems.
  • 13. Federated search Tom, a GIS analyst doing research, seeks out correlations between health and bicycle routes
  • 14. Federated search Tom searches for data in a single federated index and downloads the data as a batch.
  • 15. Vision
  • 16. Theory
  • 17. How do you make an SDI that's as compelling as modern, widely-used web services?
  • 18. Make an SDI using the best practices of these web services and projects
  • 19. General Principles  Grow Bottom Up  Align Incentives through Openness  Build it for Casual Users  Features, not Policies
  • 20. Grow Bottom-Up Reduce barriers to participation as much as possible. Be useful (if imperfect) as fast as possible. 04/26/10
  • 21. Grow Bottom-Up Start with data. Let users work with it. Generate metadata as needed. 04/26/10
  • 22. Align Incentives... Align incentives for contribution and use so growth is natural.
  • 23. Align Incentives...  Reward data providers for good contributions  Encourage users to contribute back  Make value of service transparent to system providers
  • 24. ... through Openness  Provide a reason to participate  Reward collaboration  Make it as transparent as possible
  • 25. Build it for Casual Users Using Spatial Data Infrastructure should not require expertise
  • 26. Build it for Casual Users Reading documentation is too much work. The burden is on the system developers to make it intuitive to use.
  • 27. Features, not Policies If SDI technology requires No overhead or compromises there will be No organizational resistance
  • 28. Features, not Policies Look for and implement smart technical solutions to legitimate organizational concerns.
  • 29. Vision Theory
  • 30. Context
  • 31. is a new software project to build this SDI
  • 32. Founders Want GeoNode for disaster reduction  Global Facility for Disaster Reduction and Recovery (GFDRR) and World Bank  UN International Strategy for Disaster Reduction (UNISDR)
  • 33. Builders  Not-for-profit social enterprise  Builds and supports open source geospatial software  Aims to build the Open Geospatial Web
  • 34. GeoNode is open source.
  • 35. Install it for free. Contact the developers directly. Collaborate with us and each other. Build local capacity and be independent of any vendor.
  • 36. We will soon release GeoNode 1.0
  • 37. Vision Theory Context
  • 38. What does GeoNode actually do ?
  • 39. Give a reason to participate A major problem with SDI is that people lack incentives to use it
  • 40. Problems with Portals  No benefit to registering  Few real users  No recognition or reward for the effort  Uses stick, not carrot
  • 41. SDI GIS GIS
  • 42. SDI GIS GIS
  • 43. Embed SDI in the real work of GIS practitioners, and it will have more impact.
  • 44.  Provides styling and cartography tools  Users can use the tools on data they upload  GeoNode provides a reason to participate
  • 45.  Map composer makes Maps  Maps are an important content type  They bind together ecosystem of geospatial content
  • 46. Maps, Data and Users form an web to be browsed
  • 47. Generic search engines (like Google, Bing) can crawl and rank these pages.
  • 48. Users Have Identity  People fill out user profiles to establish identity on the web  Profiles are also useful data
  • 49. Meanwhile, Metadata Pain Good metadata for geospatial data is important but hard to produce.
  • 50.  GeoNode has user profiles and features them prominently  Those profiles have ISO metadata fields within them
  • 51. Metadata Made Easy
  • 52. Metadata Published Metadata is published with open standard CSW using GeoNetwork
  • 53. Open standards and API's
  • 54.  Data published by GeoServer in OGC Services: WMS, WFS, WCS  Metadata published by GeoNetwork in CSW
  • 55. KML for Google
  • 56. We use open standards for data access. GeoNode also has open APIs
  • 57. HTTP HTTP HTTP
  • 58.  GeoNode's components interact through clean API's  Others can build apps around GeoNode  Or swap out components (Drupal...?)
  • 59. Make Content Portable
  • 60. Let Users Control Content
  • 61.  Content owners control access with easy user interface  Deep data security extends to OGC services
  • 62. We are building GeoNode to accommodate any institution's access policy
  • 63. All these features are included in the current 1.0 release candidate.
  • 64. Vision Theory Context Reality
  • 65. Future
  • 66. We have even more ambitious plans for GeoNode moving forward
  • 67. The partnership investing in GeoNode is growing The roadmap expands with the vision and needs of its partners
  • 68. Use the Social Network
  • 69. The Social for Search
  • 70. 04/26/10
  • 71. 04/26/10
  • 72.  Record statistics on usage  Let users comment on and rate content  Use that information to improve search results
  • 73. The Social for Quality
  • 74.  Ratings affect user reputation  Will encourage quality content on SDI
  • 75. Groups Matter 04/26/10
  • 76. 04/26/10
  • 77. Organizations will have a presence Allows organizational endorsement of data
  • 78. SDI Features There are also features specific to Spatial Data Infrastructure on our roadmap
  • 79. Editing
  • 80. Federation 04/26/10
  • 81. Frequently Asked Questions
  • 82. What's it made of?
  • 83. HTTP HTTP HTTP
  • 84. 04/26/10
  • 85. What about INSPIRE?  GeoServer needs WMS 1.3 to meet INSPIRE standards  OpenGeo has found partners to fund this development  It is coming soon
  • 86. Open Data Skepticism Isn't GeoNode an open data platform? Doesn't open data raise concerns about data quality and data security?
  • 87. Open Data Optimism Yes, GeoNode is designed to promote open data.
  • 88. Open Data Optimism Features like User reputation Organizational endorsement Flexible security address data quality concerns
  • 89. Open Data Optimism GeoNode supports the continuum of openness with a common platform for institutional GIS and neogeography
  • 90. What about Features X,Y,Z? We welcome your investment in new GeoNode features and involvement in the developer community.
