What TerrSet is

TerrSet is a Windows desktop geospatial system for monitoring and modeling the Earth system in support of sustainable development. It combines IDRISI GIS Analysis and Image Processing with specialized applications. GIS Analysis offers over 300 analytical tools, primarily for raster data, while Image Processing covers restoration, enhancement, transformation, and classification of remotely sensed imagery. Land Change Modeler supports land-change analysis and prediction, including REDD project modeling. Earth Trends Modeler examines image time series for long-term and seasonal climate trends and recurring patterns. Habitat and Biodiversity Modeler provides tools for habitat assessment, landscape pattern analysis, and biodiversity modeling. GeOSIRIS maps national REDD project impacts on deforestation, carbon emissions, agricultural revenue, and carbon payments. TerrSet includes utilities for importing and exporting major file and imagery formats, is COM compliant, and has IDRISI API documentation for access from other programming environments. The free liberaGIS edition is for Windows 8.1 and later or Windows Server 2008 and later; it omits Ecosystems Modeler, GStat, and parts of Climate Change Adaptation Modeler.
