Framework is a key providing for effective development, exchange, and use of geospatial as well as non-geospatial data to meet information needs generated by public domain policy. The development of multiple spatial ontologies, and their representation should be done in such a way that the computer can understand and process. The processing of queries considering these ontologies and the evaluation of results should be based on their semantics. Web becomes an immense repository of geospatial data in different geographic formats like remote sensing images, maps, textual data files, etc.
