Abstract

Expectations are important in reasoning, providing a framework within which decisions can be made. This paper describes a spatial information system which couples a large object-oriented spatial database with a graphical user interface, and incorporates ideas from artificial intelligence research, allowing the representation and use of expectations. In particular, the decision support role of spatial information systems is enhanced by the incorporation of reasoning with justifications and truth maintenance. The resulting system facilitates the assimilation, handling, and access to large amounts of dynamic and static spatial data for decision support. Inferential information of an application can be recorded, monitored, and updated.
