| Abstract: | The combined powers of Web-based geographic information systems (GIS) and on-line remote sensing tools can significantly reduce the high cost and labor associated with environmental monitoring and natural resource management. This paper introduces an integrated Web-based GIS architecture by combining three levels of geographic information services (GIServices): data archive, information display, and spatial analysis. A prototype Web site, WGAT (Web-based GIS and Analytic Tools), has been developed to provide easy access of geospatial information and to facilitate Web-based image analysis and change detection capabilities for natural resource managers and regional park rangers. The Web-based integration framework emphasizes user-oriented services, distributed network environments, metadata standards, communication protocols, client/server computation, and ubiquitous access.This paper forms a portion of the  Integrated Mobile GIS and Wireless Image Web Services for Environmental Monitoring and Management project supported by NASA s Affiliated Research Center (ARC) at San Diego State University. Funding by the NASA ARC program and matching funds from the San Diego State University Foundation are acknowledged and greatly appreciated. The author wishes to thank John Kaiser, the ARC program coordinator, and Dr. Douglas Stow, the ARC program Principle Investigator, for their coordination efforts on this project. Java programming was provided by Liang Guo, a geography graduate student at San Diego State University. |
