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.)

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.

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.

Future Development: GPS Integration and Mobile GIServices
