An architecture for ontology-based geographic information semantic Grid service

Grid computation and the Theory of Ontology provide opportunities for the integration and interoperation of Geographic Information Systems (GIS). In this paper we integrate the two technologies into the field of GIS for the semantic interoperability of the geographic information. First, we build geographic data ontology and geographic function ontology to represent geographic data and geographic functions since we consider GIS as an organic system composed of geographic data and kinds of functions related to space such as space query and space analysis and so on. Second, we present how to wrap geographic data with geo-data ontology and how to describe the geographic function with geo-function ontology. Third, we introduce an architecture which composed of Semantic Registration, Consumer Service Center and Semantic Matchmaker for ontology-based geographic information semantic grid services. Finally, we analyze future work need to do for geographic information semantic interoperability.
