12 Scopus citations


An understanding of geographic information system (GIS) databases will clarify some of the inherent problems in accessing and managing spatiotemporal data. Against this background, a semantic model that explicitly captures the spatial and temporal characteristics of GIS data and their interrelationships is described. The model is part of an overall system for solving some of the problems in accessing data from heterogeneous GIS sources.
