The 6th International Congress on Environmental Modelling and Software (iEMSs) will take place 01 – 05 July 2012 in Leipzig, Germany with a session on Geographic Information Systems and geoprocessing workflows for environmental modeling.

This session of iEMSs 2012 recognizes all of these advances as well as the natural role of iEMSs in encouraging, promoting, and facilitating continued advancements in the application of GIS software and tools to environmental Modelling. While any novel and interesting studies in the arena of GIS for environmental modelling will be considered for presentation in this session, we are particularly interested in the development and application of geoprocessing workflows, use of free and open source GIS, web-based GIS applications, tightly coupled GIS-based environmental models, GIS-based environmental decision support systems, geospatial data services, geoprocessing semantics, GIS integration technologies, and related topics.
