The Research on Spatial Process Modeling in GIS

The functionality of spatial process analysis is the foundation of GIS’s comprehensive application . To realize such a goal. it is desirable that not only the data model of GIS can represent the datasets needed by spatial process models, but also GIS is able to do multitemporal spatial analysis. But most of current GISs are static in essence, they cannot represent temporal information and temporal topology, and have not rich functionality of multitemporal analysis. Based on this point of view, a GIS spatial processes modeling system(GSPMS) is proposed , which extends current GIS, supports the whole life cycle of an GIS spatial process modeling and supports integration of models, GIS and other computer systems. This paper first describes the conception of spatial process and spatial process modeling. And then the conception framework for GIS spatial processes modeling system is investigated and a graph representative method for the framework architecture is introduced. At last the functions of GSPMS and its supporting technologies are discussed.
