Abstract: This article describes the theoretical design and an initial prototype development of a multifunctional spatial decision-support system for coastal resource and environmental management. The system has been designed to be composed of three subsystems -- one each for coastal resources, environmental, and spatial database management -- and to be implemented in the ARC/INFO geographic information systems (GIS) environment. Some key system development strategies are emphasized. A pilot analytical modeling function for coastal wetland value assessment has been completed under the resource management subsystem. The features of this function are described with respect to key technical issues in knowledge-based model integration into an existing GIS. Other proposed decision support capabilities are discussed in terms of their functions for coastal management.
