FAQ
MTW to PGM Conversion
What are MTW files?
MTW is the matrix version of the Raster Matrix Format, a format of the GIS programs Panorama and Integration, used to store digital elevation models. A file of this type contains a grid in which every cell holds the height of the terrain, so that it can serve as the basis for relief maps, profiles, slope analysis, and three-dimensional views. Its sibling, the .rsw file, belongs to the same format family but holds ordinary pictures, such as scanned maps and aerial photographs. An MTW file also records how the values should be read, including the units, which can be meters, decimeters, centimeters, or millimeters, and whether the heights are absolute elevations. It also carries simple georeferencing, so that the grid can be placed on a map.
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.
