In a large number of application domains (e.g., trafc and eet management, environmental and ecological modeling), collected data are measurements of one or more attributes of objects that occupy specic locations with respect to the Earth’s surface. Collected geographic objects are characterized by a geometry (e.g., point, line, or polygon) which is formulated by means of a ref erence system and stored under a geographic database management system (GDBMS). The geometry implicitly denes both spatial properties, such as orientation, and spatial relationships of a different nature, such as topological (e.g., intersects), distance, or direction (e.g., north of) relations.
