Model Objects: Managing an Environmental Model from within the GIS
Defining Issue: Environmental modeling is a complex process involving large spatiotemporal data sets, many variables, and intricate computer programs. The process of running the model is a task that is often nonautomated, undocumented, and difficult to change. GIS Solution: What is needed is an overall framework to perform the environmental modeling within. This framework is well handled by a GIS, a system specifically designed to handle spatial data. Methodology: This project involves the implementation of STAMP, the Spatial Temporal Modeling Program. STAMP is a loosely coupled system that integrates a GIS (ArcInfo) and an environmental model (PnET) in one modular system. It handles spatiotemporal data of different resolutions, and places constraints on the misuse of the system such as inappropriate or missing data. Software: STAMP is created within an object-oriented framework implemented using AML. The purpose of the paper is to highlight the application and its functions.
