【Abstract】 Formalization of geographical spatial image schemata is one of the keys to realize GIS interoperability and standardization, ensures that geographical information sharing reaches agreement at cognitive level and on natural language understanding,and develops intelligent GIS. It is also an important element of spatial information theory. Voronoi spatial model is proposed to represent image schemata formally. The method unambiguously defines spatial neighbor relations, establishes topological networks which can encapsulate relations between objects. The model is used for map spatial prepositions into distinct topological structure. Adopting the model, GIS can implement fuzzy geographical information query and retrieval in terms of qualitative spatial relations described by spatial prepositions in natural language.更多还原
