GIS and Environmental Modeling

Abstract

Geographical Information Systems (GIS) are a relatively new and rapidly developing class of computer applications. They show considerable potential in a growing number of application domains, regional and environmental planning and management being one of them. The integration of GIS methods adds a key technology for spatial analysis to the set of tools of applied systems analysis, and environmental systems analysis, in particular. \n \nIIASA's Advanced Computer Applications (ACA) project develops and implements environmental information and decision support systems that bring together key technologies such as database management, simulation and optimization modeling, computer graphics, expert systems, and geographical information systems. \n \nUsing several of the software systems developed at ACA as examples, the paper explores and illustrates the integration of GIS and modeling as a paradigm shift for both fields, adding more complex and dynamic analytical capabilities to the world of GIS, and better spatial data handling and display functionality to environmental models.
