IDRISI TerrSet by Clark Laboratories
IDRISI TerrSet is primarily for remote sensing and image processing.
With over 300 analysis tools, IDRISI TerrSet is as reliable as they come.
But there’s also a big focus on modeling the Earth such as in land use and climate change.
We have it ranked #23 in our list of GIS software. Let’s explore the advantages and disadvantages of IDRISI TerrSet.
There’s been a major shift in IDRISI to modeling land patterns and systems on Earth. For example, IDRISI TerrSet has several modules for this purpose:
- Land change modeler
- Habitat and biodiversity modeler
- Earth trends modeler
- Climate change modeler
- Ecosystems modeler
If you want to analyze raster data, TerrSet is a low-cost option. For example, it has modules for image processing and classification. Unlike most other GIS software, you can segment images and use OBIA classification.
Raster visualization shines in IDRISI TerrSet. It’s not only in 2D. But you can render 3D visualization. If you want to see how things change in time, there are time series animations as well.
The documentation is on the slim-side for TerrSet. There is an official IDRISI community forum. But activity is low or inactive. If you want to share your problems with other users, you’ll be hard-pressed to get any clear answers.
Because TerrSet is mostly for raster data, it’s sparse in traditional vector operations. In fact, most tools are aimed at raster analysis. For example, tools are for cost distance, surface analysis, and spatial statistics.
If you want to build a professional map product, it lacks support for advanced map layouts. There is also minimal choice in symbology and labeling options.
Summary: IDRISI TerrSet by Clark Laboratories
Since 1987, IDRISI has delivered remote sensing and image processing as an inexpensive option for analysis.
Universities around the world structure their courses around it.
And with good reason. Especially, if you want to model advanced systems on Earth.
It has vector operations. But it lacks in variety. Not only this, cartography choices are at a bare minimum.
We highly suggest it for raster modeling. But as full-fledged GIS software, you should look elsewhere.
