L. Kulik, M. Duckham, and M. Egenhofer, Ontology-Driven Map Generalization Journal of Visual Languages and Computing 16 (3): 245-267, 2005. Abstract Different users of geospatial information have different requirements of that information. Matching information to users’ requirements demands an understanding of the ontological aspects of geospatial data. In this paper, we present an ontology-driven map […]

M. Egenhofer, Spherical Topological Relations, Journal on Data Semantics III: 25-49, 2005. Abstract Analysis of global geographic phenomena requires non-planar models. In the past, models for topological relations have focused either on a two-dimensional or a three-dimensional space. When applied to the surface of a sphere, however, neither of the two models suffices. For the […]
