Clark Labs - The TerrSet Constellation
TerrSet provides an unprecedented set of tools for monitoring and modeling the Earth system. IDRISI was the first GIS and Image Processing System specifically developed for a microcomputer platform. Over the decades that followed, IDRISI has matured into a research grade system for geographic analysis with ground breaking developments in areas such as multi-criteria/multi-objective decision making, machine learning and time-series analysis. The IDRISI collection of nearly 300 program modules provide the basis for a large number and variety of geospatial analytical operations that can be choreographed with the assistance of a variety of graphical and programmatic modeling tools.
The full TerrSet constellation includes eight components. The first two general-purpose toolsets are the core of TerrSet:
- IDRISI GIS Analysis
- IDRISI Image Processing
The remaining components are vertical applications focused on a specific task sequence to monitor and model the Earth system:
- The Land Change Modeler (LCM)
- The Earth Trends Modeler (ETM)
- The Habitat and Biodiversity Modeler (HBM)
- The Ecosystem Services Modeler (ESM)
- The Climate Change Adaptation Modeler (CCAM)
- GeOSIRIS – a special tool for national level REDD (Reducing Emissions from Deforestation and Forest Degradation) planning.
Current USC students have two low cost options to get TerrSet licenses:
- Student License ($99.00) does not expire.
- Student Starter ($49.00) expires in one year.
