FAQ
VCT to PGM 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 PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
