Abstract :
Spatial Information Search Engine (SISE), aiming to search the World Wide Web for online geographic information to meet the end users needs, is a totally new research area in the field of spatial information sharing. In this paper we introduce an OpenGIS WMS specification based SISE prototype system. This SISE prototype is capable of discovering available WMS servers dynamically, choosing qualified WMS servers according to the client request, and fetching the matched geographical information from them transparently. The system architecture, working principles, detailed function of each component, implementation strategies and system performance test results of this SISE prototype are introduced.
