Paper Abstract

Recent advances in open geospatial web service, such as Web Coverage Service as well as corresponding web ready data processing service, have led to the generation of large amounts of OGC enabled links on Internet. Recently a few search engines that are specialised with respect to geographic space have appeared. However, users do not always get the effective OGC WCS link information they expect when searching the Web. How to quickly find the correct spatial aware web service in a heterogeneous distributed environment has become a "bottleneck" of geospatial web-based applications. In order to improve the retrieval efficiency of OGC Web Coverage Service (WCS) on WWW, a new methodology for retrieving WCS based on clustering capability aware spatial search service middleware is put forward in this paper.
