Presentation Transcript

    Slide 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

    Slide 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.

    Slide 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

    Slide 5: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.

    Slide 6:Data Warehouse

    Use ArcCatalog to create metadata in XML for ADAR and IKONOS images.

    Slide 7: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.

    Slide 8:Interative Internet Mapping

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

    Slide 10:Interative Internet Mapping

    Use JavaScript to create dynamic display of remote sensing images with different map layers.

    Slide 11: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.

    Slide 12:MTRP BMX (motor-crossing bicycling) GPS Data in ArcIMS

    Slide 13: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).

    Slide 15:Image Overlay Function (Change Detection)

    Image Processing Image Filtering Image Viewing Image Magnifier Panoramic View

    Slide 18: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.)

    Slide 19:Internet Map Server

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

    Slide 20: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.

    Slide 22: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.

    Slide 23:Future Development: GPS Integration and Mobile GIServices
