Hawaii Pacific GIS Conference 2012: Real-Time Data Acquisitions - Bringing Internet Data Content into GIS Applications

  1. 1. Bringing Internet Data Content into GIS Applications Rod LowHawaii Pacific GIS ConferenceHonolulu, March 5-7, 2012
  2. 2. Application Platforms • Desktop • Web Browser • Mobile Device
  3. 3. Application Platforms • Desktop • Web Browser Need Server for GIS Data & Functionality • Mobile Device
  4. 4. Application Platforms • Desktop • Web Browser • Mobile Device Can Survive Interruptions of Service
  5. 5. •Emergency Management Situational Viewer•Accessible from Honolulu EOC (Emergency Operation Center) & Remotely•Runs in Web Browser (IE specified)•Client uses Adobe Flex with ArcGIS Flex API 2.3•Server uses ArcGIS 10 Server with Enterprise SDE
  6. 6. HONUA • Situational Viewer • Mashup
  7. 7. Approaches • Hyperlinks • Feeds • Services
  8. 8. Approaches • Hyperlinks - Open a browser pointing to the specified URL - Does not digest the information • Feeds • Services
  9. 9. Approaches • Hyperlinks • Feeds - GeoRSS Standard - Other (often legacy) • Services
  10. 10. GeoRSS feeds • RSS is an XML Standard - GeoRSS Standard adds Spatial Tags Real world seldom completely correct:
  11. 11. Other Feeds • Any regularly updated web site, any format • Example NOAA weather feeds • Tools available for Web Scraping - Generic (e.g. XML to CSV) - Vendor-Specific (e.g. import to SDE)
  12. 12. Approaches • Hyperlinks • Feeds • Services
  13. 13. Services Map & Image Services Geometry Feature Service Special (examples) Geocoding Network Service 3 D Service Geoprocessing Service
  14. 14. Services Map & Image Services • Basemap - Cached Tiles for improved performance - Fixed Scales • Dynamic Service - User control over Visibility, Scale & Symbology
  15. 15. Accessing Services • SOAP (older approach) • REST “endpoint” DEMO: http://geodata.sdal.hilo.hawaii.edu/ArcGIS/rest/services /Statewide/Hazards/MapServer
  16. 16. Geometry Service • GIS Functionality – e.g. re-project data
  17. 17. Feature Services • Added at ArcGIS 10 • Allows Web Editing
  18. 18. Specialized Services • Geocoding • Network Service • 3 D Service
  19. 19. Geoprocessing Services • You have more control • If a specialized service is available, it will be much more efficient
  20. 20. Putting it all together • ERG (Chemical Spill) • Need to know wind direction - Web Scrape the NOAA current weather - Geoprocessing to find nearest weather gage
  21. 21. Conclusions• GeoRSS standard needs to be better followed Until then: - Customized code needed for reading most XML - Web Scraping useful• Even desktop benefits from Internet Data - Current Conditions might be necessary for GIS Analysis• Synergy in combining links, feeds & services
