FAQ
GSB to PPM Conversion
What are GSB files?
GSB (Grid Shift Binary) is the file extension of the NTv2 format, short for National Transformation version 2, developed in Canada by Natural Resources Canada for converting map coordinates from one geodetic datum to another. When old maps were based on one model of the Earth and new surveys use another, the same place ends up with slightly different coordinates, and a file of this type records how far each point has to move. It covers an area with a net of points and stores the shift in latitude and longitude at each of them, usually together with an estimate of the accuracy. The format later spread to other countries, including the United Kingdom, Switzerland, and Australia, and it is widely used in surveying, cadastre, and GIS.
What are PPM files?
PPM or Portable Pixelmap files are image files included in Netpbm, an open source graphics program. The other widely used Netpbm formats are PGM (Portable Graymap) and PBM (Portable Bitmap). All three are image formats and are sometimes called collectively PNMs (Portable Anymap format). While PGMs contains grayscale images, PPMs include color images and they represent intermediary files used in the conversion of less known formats using the Portable Bitmap Utilities. PPM files are mostly operated on UNIX and Intel-based platforms.
