Abstract

The development of spatially-distributed multimedia models has traditionally required a fixed geometric grid or mesh, or an ad hoc spatial representation for a compartment-type model. As geographic information system (GIS) applications have matured, an alternative approach is evolving where the spatial components of the model and the physical-processes components are developed separately. At run time the physical process models are mapped onto the spatial domain, the simulation model is constructed and evaluated, and results are exported to the GIS system. In this approach one or more generic ‘local’ models are developed, then replicated across a spatial domain defined by a GIS system, connected to sources of spatial data, and finally the local models are interconnected to allow flows of information, physical media, and contaminants between the local mode
