Abstract
There is provided a spatial reasoner for reasoning a topological relation and a directional relation between two geo-entities. The spatial reasoner includes a plurality of spatial knowledge bases in which spatial relations are defined; a spatial reasoning engine configured to infer new spatial relations through a cross consistency check of the spatial knowledge bases; and a query processing engine configured to answer to a spatial query using the new spatial relations inferred from the spatial reasoning engine. Therefore, it is possible to perform efficient and accurate spatial reasoning.
