FAQ
VCT to CAL Conversion
What are VCT files?
VCT is the vector file of IDRISI, a GIS and remote sensing system developed by Clark Labs and later renamed TerrSet. A file of this type holds the shapes of one map layer: points, lines, polygons, or text labels, each with the coordinates of its vertices and a single number that identifies it or gives its value. The descriptive attributes of the objects, such as names or classes, are not inside the file but in separate attribute tables linked by that number. Every VCT file is accompanied by a small documentation file with the .vdc extension, which describes the data, and often by a reference file with the coordinate system. Only one kind of shape is allowed in a file, so a map with roads and buildings needs at least two of them.
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.
