FAQ
RST to CAL Conversion
What are RST files?
RST is the raster image file of IDRISI, a GIS and remote sensing system developed by Clark Labs at Clark University in the United States and later renamed TerrSet. A file of this type holds a single layer of a map, such as a land cover classification, a soil map, an elevation model, or one band of a satellite image, as a plain grid of values. The meaning of the numbers is not stored in the file itself but in a small text file with the same name and the .rdc extension, which gives the number of columns and rows, the type of the values, the coordinate system, and the range of values. A color table may come in a third file with the .smp extension. Files in this format were originally saved with the .img extension, which was changed to avoid confusion with other formats.
What are CAL files?
A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
