Paper Abstract

Research on geographical spatial reasoning aims at expression of spatial relationships, geo-spatial reasoning rules and reasoning mechanism that could be used for geo-spatial knowledge discovery and spatial analysis. Spatial reasoning is intelligent spatial data processing technology in support of geo-spatial decision-making. Geographic ontology is clear formal definition of geographical concepts, which defines the basic terms and relations of these concepts, and the rules combining these terms and relationship. Therefore, it can well meet the formal knowledge representation requirement for geo-spatial reasoning that carry out reasoning by using geographic ontology. In this paper, methods of creating geographic ontology are discussed, and the rules based on spatial reasoning are summarized. Furthermore, a path query method based on geographic ontology is proposed, by creating a road ontology system and the corresponding administrative region ontology system, it can be used to solve large-scale spatial path query problem.
