Basic concepts and tools of the shell will be introduced and its key functionalities will be discussed in the present part. The shell is capable of handling spatial data and models in an integrative and interactive manner in addition to rule-based inference under certainty and uncertainty. It runs on the Windows environment with extensive use of the DLL and DDE technologies for dynamic model and data communication. It can be employed to build efficiently a large variety of spatial decision support systems with GIS, models, and domain-specific knowledge as integrative components. © 1997 OPA (Overseas Publishers Association) Amsterdam B.V.
