FAQ
GXF to CG4 Conversion
What are GXF files?
GXF (Grid eXchange File) is an open text format for exchanging gridded data between different programs. It was developed by Geosoft, a Canadian company that makes software for geophysics, and it became the standard way of passing gravity and magnetic survey maps between systems. Such a map is a net of equal cells, and each cell holds a measured value, for example the strength of the Earth's magnetic field. A GXF file stores these values as plain text, together with the information needed to place the grid on the ground, such as the spacing between points and the map projection. Because the file can be opened in any text editor and does not depend on the software that made it, it is also used to share elevation data and other kinds of surfaces.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
