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.
Data Warehouse

Use ArcCatalog to create metadata in
XML for ADAR and IKONOS images.
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.
Interative Internet Mapping

Apply ESRI’s ArcIMS software package to create a Internet
Map Server on Microsoft Window 2000 Server with IIS 5.0.
Interative Internet Mapping

Use JavaScript to create dynamic display of
remote sensing images with different map layers.
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.
MTRP BMX (motor-crossing bicycling)
GPS Data in ArcIMS
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).
Image Overlay Function
(Change Detection)
•Image Processing
•Image Filtering
•Image Viewing
• Image Magnifier
• Panoramic View
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.)

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.

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.
Future Development:
GPS Integration and Mobile GIServices
