This session focuses on the integration of geographical information science and environmental modelling. The technology of GIS is well established with tools for management, visualisation, and analysis of environmental information. With system interoperability GIS may be coupled to different types of environmental models, or alternatively new geoprocessing operations are being developed to directly support environmental modelling within GIS. There are also new paradigms emerging that relate spatial patterns to environmental landscape processes. This session invites papers on integrating GIS and environmental models that address technology issues, methodologies and innovative applications in the areas of: geoprocessing operations, coupled models, and spatial analysis to relate pattern with landscape processes.
