  1. Geospatial One-Stop Gateway for Discovery and Access CWG Workshop December 4, 2007 Rob Dollison rdollison@usgs.gov

  2. What I’m Going to Cover • NSDI Evolving • GOS Portal Enhancements • Example New ‘Service’ - Integration with GOS • How should we measure Agency Participation in GOS?

  3. Evolving Spatial Data Infrastructures GIS Portals Clearinghouses • Application focus • IT standards • Interoperable • System-oriented • Data focus • Geo-standards • Top down File Transfer • Ad hoc • Data focus • FTP transfer • Bottom up

  4. Some Lessons Learned • Metadata is difficult • Difficult to publish • Difficult to be consumed by end users • Not all data is available to users • Not all data is registered • Searching data is not easy • Too many steps to contribute content • Result • GIS Portals aren’t reaching their full potential

  5. How should our Metadata evolve? Large User Community: General Users Brief Metadata is Sufficient KML, Tagging, Dig, … Verbose Metadata is Desired Limited User Community: GIS Specialist ISO 19139, FGDC

  6. External Drivers: The Internet is Evolving Source: http://gismatters.blogspot.com/

  7. Evolving Spatial Data Infrastructures Services Architecture GIS Portals • Service Oriented • Focus on Content • Integration in Business Process Clearinghouses • Application focus • IT standards • Interoperable • System-oriented • Data focus • Geo-standards • Top down File Transfer • Ad hoc • Data focus • FTP transfer • Bottom up

  8. Architecture JSR-168 IBM WebSphere Portal WMS Single Sign-on and Personalization WFS/GML Apps FGDC Map Viewer Publish Search WCS ArcIMS ISO WMC Other JSR-168 Portlets Open LS Gazetteer Catalog Service GIS Portal Toolkit Metadata Harvester CS-W CS-W Z39.50 Z39.50 Google http WAF / XML ESRI-Google Spatial Extender Natural Language Search OAI OAI-PMH Google Search Appliance ArcIMS Our ‘National Catalog’ Open LS Gazetteer Metadata Catalog COTS & Standards Based ( Programmatic Connection )

  9. Current Status Over 150,000 Total Records Over 2,500 in Marketplace 55% Fed – 45% NonFed Over 60,000 Visits/Mo.

  10. What’s New • New Search Interface • Search Results Visualization • Data set footprints now show in map • New Content Type Icons • View results as icons • Download search results to Excel • Search in the Marketplace • View Map Services on a Globe • Customer Satisfaction Survey

  11. New Search Interface • Map more closely tied to search • Uses international place gazetteer • Search the entire database or just the Marketplace

  12. Search Results Visualization Data set footprints show in map List results are linked to map footprints to allow easy visualization of the coverage area of each dataset.

  13. Search by Publisher

  14. New Content Type Icons

  15. Access Functions – Context Menu • Access the function menu by putting your mouse cursor over the data content icon.

  16. View Results as Icons

  17. Download Search Results to Excel

  18. View Web Map Services on a Globe

  19. New Marketplace Interface • Text and Location Search • Study Area Footprints Shown in Map • Similar Functionality to Search Interface

  20. Example New Service from FGDC Coming soon in 2008 • Is this map service working? • How Responsive is it? A New Symbol next to ‘Live’ Map Services Linked to a detailed report….

  21. WMS Detailed Report from FGDC • Report Information: • GOS Registration Information • Health Test Results • Reliability Rating • Responsiveness Rating • Potential Service Issues • Recommendations

  22. Measuring Agency Participation • How should we measure participation? • Encourage progress? • Proposed – • Q2 and Q4 OMB EGov Milestones • Published our new metadata • Published our new data plans • Reviewed and updated our A-16 Data Communities (Links Working) • Registered Map Services and Applications? • Supporting data from the portal (standard form?) • FGDC Annual report used to discuss other participation – establishing web services etc…
