Opis

Database research in the 1990s has focused on providing support for nonstandard applications. One important domain is representation and processing of spatial information, such as in geographic information systems. Spatial data types provide a fundamental abstraction for modelling the structure of geometric entities, their relationships, properties and operations. This monograph surveys this field and introduces a general framework for the formal definition and implementation of spatial data types.
