  1. NASA ARC Project Web-based Geographic Information Services and Analytic Tools for Natural Habitat Monitoring and Management Department of Geography, San Diego State University Ed Almanza & Associates

  2. Web-based GIServices • Data Warehouse (Catalog & Metadata) • Interactive Internet Mapping Facilities (Internet Map Servers) • On-line Analytical Tool (Java applets) for Remote Sensing Images and Change Detections.

  3. Web-Site: • Http://map.sdsu.edu/arc • Required Web Browser: Java applets capability (IE 5.0 or Netscape 4.0 later) • Suggested Screen Resolution 1024x768

  4. Project Overview • Create a prototype framework for Web-based GIServices in Environmental Monitoring. • Explore different Internet technologies. • Integrate/Customize different software and programs together. • Case Study Areas: Mission Trail Regional Park (MTRP) with ADAR and IKONOS images.

  5. Data Warehouse • Use ArcCatalog to create metadata in XML for ADAR and IKONOS images.

  6. Data Warehouse • Create two version of metadata: FDGC Standard and Simple version (with the most essential elements). • Use HTTP to allow users to download images.

  7. Interative Internet Mapping • Apply ESRI’s ArcIMS software package to create a Internet Map Server on Microsoft Window 2000 Server with IIS 5.0.

  8. Interative Internet Mapping • Use JavaScript to create dynamic display of remote sensing images with different map layers.

  9. GPS / Remote Sensing Images Data Integration • GPS data collected by MTRP Park Rangers with their Trimble GPS units and Pathfinder Office software. • We converted the GPS data sets to Shapefiles and integrate them with our ArcIMS server.

  10. MTRP BMX (motor-crossing bicycling) GPS Data in ArcIMS

  11. On-line Analytical Tools • Java Applets (Java Advanced Imaging API and Java 2D API) • JavaScript (dynamic Web display, communicating with Internet Map Servers) • Existing Software (Panoramic Viewer).

  12. Image Overlay Function(Change Detection)

  13. Image Processing • Image Filtering • Image Viewing

  14. Image Magnifier • Panoramic View

  15. Key Technologies • Java Programming (cross-platform) • XML (Extensible Markup Language) for metadata and communication with Internet Map Servers (ArcIMS – ArcXML). • Internet Map Server (ESRI’s ArcIMS, AutoDesk’s MapGuide, INTEGRAPH’s GeoMedia Web Map, SmallWorld’s Internet Application Servers, etc.)

  16. Internet Map Server • Three-Tie Architecture • http://map.sdsu.edu Client (Web browser) + Java applets Internet Map Server ArcIMS Web Server map.sdsu.edu Internet Client (Web browser) + IMS Viewer Client (Web browser) Regional Database (GIS)

  17. Expert Review and User Testing • Expert review and questionnaire • Tutorial • Two user scenarios: • Equestrian Facility Development • BMX site and Trails Management • Participants: two MTRP rangers, one graduate student, one GIS specialist (former graduate student). • Location: MTRP visitor center and CESEAR lab.

  18. Preliminary Findings • Easy to use (comparing to other GIS/Remote Sensing software) • Need to clarify some information in metadata and IMS tools (terminology from SANDAG and FGDC). • Need to clarify temporal or seasonal information about remote sensing images and GIS data sets. • These tools will be a good information resource for MTRP visitors. • IMS: Difficult to view/query data layer while RS image is in the background. • ADAR and IKONOS magnifier tools could be added into the Data Warehouse section.

  19. Future Development: GPS Integration and Mobile GIServices
