Access comprehensive support and learning materials for TerrSet, including the latest release, liberaGIS, and earlier versions such as IDRISI Selva, TerrSet, and TerrSet 2020. This hub directs to our Support Center, detailed FAQs, and a library of technical resources. Whether you’re seeking guidance on advanced geospatial modeling, exploring software features, or resolving technical issues, these resources are designed to support your research and analytical work. 

The Clark Center for Geospatial Analytics (formerly Clark Labs) supports its user community through a robust online Support Center. This platform serves as an interactive forum for users of the TerrSet system, offering:
  • A knowledge base featuring FAQs and documentation.
  • A space to ask questions, share insights, and collaborate with other users.
The Support Center also provides access to submit technical support tickets related to routine inquiries—such as those regarding installation or software errors. For more specialized support (e.g., adaptation of the software for unique applications), please reach out to us at: cga@clarku.edu

IDRISI Applications Programming Interface 
Documentation for developers for the IDRISI API, the application programming interface for the TerrSet System. TerrSet is fully COM compliant, allowing access to functionality from other programming environments.

Clark Labs’ Modified Version of Gstat
Document of modifications and the source code of Gstat, a free software utilized within TerrSet. Gstat was only released TerrSet2020 and earlier (not liberaGIS). (That last sentence is new.  Note: this bit about Gstat is legally required as part of the GNU agreement under which we distributed gstat up until this release.) 

TerrSet 2020 Slideshow
PDF of screenshots, highlighting the most recent capabilities in the TerrSet version. (19MB)(This is a bit outdated, but we don’t have a replacement and probably won’t any time in the near future.  Better to keep it, to give a general sense of the software, even if it is outdated.)
