Study on GIS-Based Modeling of Spatial Processes Simulation
基于GIS的空间过程模拟建模方法研究

The functionality of spatial process analysis is the foundation of GIS's comprehensive applicaton. To realize such a goal, it is desirable that not only the data model of GIS can represtent the datasets needed by spatial process models and output datasets, 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. Completely changing or largely modifying data model of current GISs and developing a lot of spatial process models which may have very narrow applications could not be accepted by the GIS vendors. Based on this point of view, a method to extend current GIS to support spatial process simulation modeling is proposed.
