TerrSet is an integrated geospatial software system for monitoring and modeling the earth system for sustainable development. The TerrSet system incorporates the IDRISI GIS Analysis and IDRISI Image Processing tools along with a constellation of vertical applications. TerrSet offers the most extensive set of geospatial tools in the industry in a single, affordable package. There is no need to buy costly add-ons to extend your research capabilities.
Along with the software features mentioned below, TerrSet also includes utilities for import and export of all major file and imagery formats along with comprehensive documentation and tutorials.
TerrSet 2020 Software Features
The Ecosystem Services Modeler (ESM) is closely based on the InVEST tools developed by the Natural Capital Project. Fifteen ecosystem service models have been implemented. In this illustration, ESM is used to evaluate water yield and water scarcity in the year 2100 for the state of Massachusetts. The predicted land cover input was generated by Land Change Modeler in TerrSet and the predicted precipitation was generated by the Climate Change Adaptation Modeler in TerrSet. The outputs from water yield are used to calculate hydropower potential at the subwatershed level in the year 2100.
The SEGMENTATION module creates an image of segments that have spectral similarity across many input bands. This example shows two levels of segmentation from panmerged Quickbird imagery. The image on the left uses a larger similarity threshold than the one on the right, resulting in more generalized, less homogeneous segments. Altering this threshold allows for the segmentation of objects, such as forest stands, tree crowns or buildings.
The Earth Trends Modeler (ETM) is specially designed for the analysis of earth observation image time series. In this illustration, a series of 348 global images of monthly NDVI vegetation index data were analyzed for the presence of trends in seasonality. Pixels colored gray (which are almost absent) indicate a stable seasonality. All other colors represent trends. ETM provides an interactive legend (lower left) to interpret the trend for any area (the area in eastern Alabama and western Georgia in this case). The green curve represents the beginning of the series (1982) while the red one represents the end (2010). The X axis is time and the Y axis is NDVI. As can be seen, NDVI has generally increased with a growing bimodality. Spring is coming a bit earlier (11 days) and the autumn is extending longer (almost 30 days).
