摘要：With the growing need of spatial data for almost all decision support systems a huge amount of data about earth has been collected. The data being captured use different software tools making them heterogeneous both in terms of storage and access mechanisms. For integration of data from multiple heterogeneous sources there is the need of interoperable access for data. Web service technology exactly fits into that requirement and an increasing number of spatial services are being made available on the web. But general catalog-based service repository is inefficient for providing semantic relevance of the requested service. The application of ontology in the form of conceptual schema for the domain is ideal for context aware service discovery. The application of ontology for service brokering in geo-computation has been studied in this paper
