|Operating system||Microsoft Windows|
TerrSet (formerly IDRISI) is an integrated geographic information system (GIS) and remote sensing software developed by Clark Labs at Clark University for the analysis and display of digital geospatial information. TerrSet is a PC grid-based system that offers tools for researchers and scientists engaged in analyzing earth system dynamics for effective and responsible decision making for environmental management, sustainable resource development and equitable resource allocation.
Key features of TerrSet include:
- a complete GIS analysis package for basic and advanced spatial analysis, including tools for surface and statistical analysis, decision support, land change and prediction, and image time series analysis;
- a complete Image Processing system with extensive hard and soft classifers, including machine learning classifiers such as neural networks and classification tree analysis, as well as image segmentation for classification;
- Land Change Modeler, a land planning and decision support toolset that addresses the complexities of land change analysis and land change prediction.
- Habitat and Biodiversity Modeler, a modeling environment for habitat assessment and biodiversity modeling.
- Ecosystem Services Modeler, a spatial decision support system for assessing the value of natural capital.
- Earth Trends Modeler, an integrated suite of tools for the analysis of image time series to assess climate trends and impacts.
- Climate Change Adaptation Modeler, a facility for modeling future climate and its impacts.
- GeOSIRIS-REDD, a national-level REDD planning tool to assess deforestation, carbon emissions, agricultural revenue and carbon payments.
History and background
IDRISI was first conceived in 1987 by Prof. J. Ronald Eastman of Clark University, Department of Geography, as an accessible yet robust PC-based GIS. Dr. Eastman continues to be the prime developer and chief architect of the software. In January 2015 Clark Labs released the TerrSet Geospatial Monitoring and Modeling software, version 18. Besides its primary research and scientific focus, TerrSet is popular as an academic tool for teaching the principal theories behind GIS at colleges and universities.
Since 1987, IDRISI, and now TerrSet, has been used by professionals in a wide range of industries in more than 180 countries worldwide. Environmental managers and researchers benefit from the unsurpassed range of geospatial tools—over 300 modules for the analysis and display of digital spatial information.
Based within the Graduate School of Geography at Clark University, Clark Labs and its software tools are known for pioneering advancements in areas such as decision support, uncertainty management, classifier development, change and time series analysis, and dynamic modeling. Partnering with such organizations as The Gordon and Betty Moore Foundation, Google.org, USDA, the United Nations, Conservation International, Imazon and Wildlife Conservation Society.
The software is named after cartographer Muhammad al-Idrisi (1100–1166).
In 2015, Clark Labs released a new product called TerrSet. TerrSet greatly expands the modeling capacity of the base IDRISI toolset.
