Topological Relations from Metric Refinements

Published: Nov 1, 2009 Author(s): Dube, Matthew P., Egenhofer, Max J. Abstract: Naive Geography’s premise “Topology matters, metric refines” calls for metric properties that provide opportunities for finer grained distinctions than the purely qualitative topological relations. This paper defines a comprehensive set of eleven metric refinements that apply to the eight coarse topological relations between two regions that […]

Establishing Similarity Across Multi-Granular Topological-Relation Ontologies

Published: Jun 1, 2009 Author(s): Dube, Matthew P., Egenhofer, Max J. Abstract: Within the Geospatial Semantic Web, selecting a different ontology for a spatial data set will enable that dataís analysis in a different context. Analyses of multiple data sets, each based on a different ontology, require appropriate bridges across the ontologies. This paper focuses on establishing such […]
