✦ Synopsis

We discuss locations as defined by their qualitative spatial relations to other features, dubbed qualitative locations (QL). We further propose a mechanism to handle queries with qualitative locations in geospatial information systems. For the realization of the mechanism for QL-based queries, we propose a conceptual framework that takes advantage of models of qualitative spatial reasoning to bridge the gap between conventional metric spatial information systems and the general publicΓ•s common-sense query of spatial relations in natural language.

Future generations of databases will store increasing amounts of pictorial and other visuospatial material. Among other methods, these will require retrieval techniques which exploit memory for the location of objects in pictures stored within the database. Experiments are reported in which subjects
