FAQ
MPR to CAL Conversion
What are MPR files?
MPR is the raster map file of ILWIS (Integrated Land and Water Information System), a GIS and remote sensing program developed at the ITC in the Netherlands for land use, water management, and environmental studies. A raster map is a grid of square cells, and every cell carries a value, such as a height, a reflectance recorded by a satellite, a land use class, or a plot number. The .mpr file is the readable description of such a map, and it points to the file that holds the cells, to the georeference that places the grid on the ground, and to the domain that explains what the values mean. A map can have up to about two billion lines. Maps in this format can be created in ILWIS or imported from many other raster 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.
