chapter  32
Integrated Topological and Directional Reasoning in Geographic Information Systems
ByJayant Sharma
Pages 14

This chapter deals with computational methods that exploit qualitative spatial knowledge, in addition to geometric information, for making inferences about objects in a spatial database. The motivation is to provide such systems as geographic information systems (GIS), which manage the storage and retrieval of large data sets, with intelligent mechanisms to deal with complex spatial concepts for data selection and integration. One purpose of these intelligent mechanisms is to enable intuitive interaction with the data by capturing and reflecting the user's perception of the world. Intuitive interaction entails providing facilities for the representation of qualitative spatial information and making inferences.
