A Web Services Framework for Integrated Geospatial Coverage Data

This paper refers Web Coverage Service which provides geospatial data as Coverages that are geospatial information representing space-varying phenomena. It also takes care of Coverage Portrayal Service that defines a standard operation for producing visual pictures from coverage data. This paper proposes an interoperable and integrated coverage service. It takes international recommendations of coverage operations, WCS and CPS, on web environments and implements them in a single server system. For interoperability, it takes XML Web Services enabling cooperation of separate systems regardless of their platforms and languages. Through this paper, we are able to propose a prototype model for real geospatial services from an implementation viewpoint. It is expected that this endeavor can develop existing HTTP-based geospatial web services into XML Web Services, which enhances the Internet GIS services to give users fundamental benefits of ubiquitous accesses.
