Applying spatial reasoning to topographical data with a grounded geographical ontology

By D. Mallenby and B. Bennett

Abstract

Grounding an ontology upon geographical data has been pro-\ud posed as a method of handling the vagueness in the domain more effectively. In order to do this, we require methods of reasoning about the spatial relations between the regions within the data. This stage can be computationally expensive, as we require information on the location of\ud points in relation to each other. This paper illustrates how using knowledge about regions allows us to reduce the computation required in an efficient and easy to understand manner. Further, we show how this system can be implemented in co-ordination with segmented data to reason abou
