This release contains the latest version of TerrSet liberaGIS (v20.00). You can download the setup file at the bottom of this section. Microsoft Access Database Engine is also included for download. Source Code.zip or Source Code.tar.gz folders contain files from TerrSet's GitHub repository such as the installation guide and license.

What’s new in liberaGIS

The new version of TerrSet/IDRISI, called liberaGIS, includes:

  • An improved Land Change Modeler tool with support for Jurisdictional and Nested REDD (JNR), a framework that helps governments protect and manage forests and mitigate the impacts of climate change. REDD stands for “Reducing Emissions from Deforestation and forest Degradation.” Clark Labs developed these tools for Verra, the leading standards organization for the conduct of REDD projects.

  • In the Earth Trends Modeler a new tool for climate teleconnection analysis has been added. This tool is used to identify recurrent climate patterns over wide spans of the earth that are generally obscured by short-term variability (El Niño and La Niña, the periodic warming and cooling of the central and eastern Pacific, are well known examples that lead to dramatic weather changes worldwide, but many others exist).

  • A major suite of tools for raster editing. Satellite images and many environmental datasets are best stored as raster images – fine numeric matrices that can be displayed as colored pixels on digital displays. Maps created from satellite images often need manual editing. Based on the experience gained from 10 years of mapping shrimp aquaculture and its impacts on mangroves in the tropics for the Gordon and Betty Moore Foundation, Clark Labs has developed a suite of special tools for facilitating the process.

The new version is streamlined by removing components that relied on external programs that are no longer supported by their original developers. These include:

  • The deprecated MAGICC/SCENGEN 5.3 tools from the National Center for Atmospheric Research (NCAR) originally developed for the fourth IPCCC climate assessment.

  • The United Nations’ Food and Agriculture Organization’s (FAO) standalone ECOCROP database of information on plant characteristics and crop environmental requirements, now replaced with an online tool. Because of this and the previous point, the Climate Change Adaptation Modeler has been removed and some of the components were moved to the Habitat and Biodiversity Modeler.

  • The Ecosystem Services Modeler, based on the InVEST toolset from the Natural Capital Group has been removed. Newer open-source and freely available tools are now directly available from that group, and work well with TerrSet/IDRISI.

New functionality:

  • SATA (Sequential Autoencoder Teleconnections) in ETM: a technique which is similar in intent to EOT, but dramatically faster.
  • Display: Right-click on Legend now has option to create a  point file of that category (“Create Vector Points Current Class”).
  • PCorBinary: corrects a binary-class probability image for an artificially balanced sampling.
  • PriorCorrect: corrects a set of posterior probability images for the proper prior probability in the context that the classifier is used.
  • UDef-A: Unplanned Deforestation Allocation Tool added to Land Change Modeler
  • New panel in LCM – Test and Selection of Driver Variables
  • Digitize Update (can update a raster file while/after digitizing on top of it)
  • Monitor areas of training sites while you’re digitizing them
  • Hotkeys – toggle layer on/off; show the area in GEE.
  • Reclass- added geometric reclass option
  • Image Calculator – added support for scientific notation
  • SCALAR – added new option to Exclude background values from the calculation

Fixed

  • RasterVector – polygon to raster option. The "touches any part of the cell" option only worked in combination with the give the output cd the ID of the vector file. Now it also works for the “presence” option.
  • RasterVector – polygon to raster option. There was sometimes a gap (cells of zeros) between polys if line on diagonal. There were some gaps between polygons in cells where the diagonals fell directly on the center point - neither polygon (left or right) was getting assigned to that center cell. This was related to precision in the point sorting algorithm and is fixed.
  • LCM - Change Prediction - Validate (last panel) limited to 256 combinations
    This was a problem if you had more than 7 land use categories in your images in LCM, because Validate does a three-way crosstabulation, which easily goes over 256 combinations of found categories in the images. Now CROSSTAB allows there to be > 256 combinations for that if called from LCM’s Change Prediction Validate. Added the legend descriptions to the Comments of the output file if the category code was > 255.
  • LogisticReg – If the input file was super big, and therefore, the number of sample cells was very big, sometimes the sample point IDs would go negative (have negative IDs). This is fixed.
  • Stretch – Histogram Equalization option – was putting fewer values into the first and last categories. Now they should be roughly equal (as much as possible without splitting categories from the input image into more than one output category).
  • Sample - mask - problems with large files
    If file is very large, then it was having trouble with points near the bottom of the image if there is a mask.  It wasn't putting all the points there for stratified or systematic for very large file 47k x 35k, 1250 pts).
    There were some incorrect variables in the section of code where it would read the mask file so it might read the output file instead of the input file and wrongly choose whether or not to include that point.
    Progress reports were improved.
  • EOT (ETM's EOT) – Fixed : bad values in component 1 if integer input files.
    Output component 1 values (seen on ETM's Explore tab, explore series) were wrong (in the wrong range altogether (e.g. 4,900,000 instead of in the 2000-6000 range) if the input images are integer binary.
  • ETM - Preprocess - Denoise - Cumulative Sum and Cumulative Median options - wrong metadata put in output TSF (the metadata file for the time series). The start and end month were wrong. Luckily, the output images were correct.
  • RECLASS - Added ability to properly deal with background values to the Equal Intervals option in Reclass.
  • MOLA – Fixed bug where would get an invalid floating point error if area requested is > 1,046,529 cells. Also, better progress reports.
  • CSV2AVL – now can work on files that do or don’t have a header row. It also now correctly calculates min/max for the first field/column.
  • Tutorial Data file lawn grass.rst in Introductory IP folder had incorrect max value in rdc and had some random striping in the image. Fixed the image & metadata.
  • Extract – added more error checking to prevent untrapped error if max value in metadata (rdc) is incorrect.
  • TerrSet Explorer - Add resource folder and subfolders option was skipping folders that had attribute of “folder is ready for archiving”.
  • LCM – more descriptive error message for Dynamic variables missing classes or legend for roads.
