Geographic Database Systems

Max J. Egenhofer, NCGIA, University of Maine

This research area includes the development of data models for geographic information systems including consistency constraints for spatial data represented at multiple representations, spatial query languages, spatial query processing, spatial similarity retrieval, and their use under distributed environments such as Smart Maps.
