This is a raster exchange format propagated by Geosoft, and made a standard in the gravity/magnetics field. GDAL supports reading (but not writing) GXF-3 files, including support for georeferencing information, and projections.

By default, the datatype returned for GXF datasets by GDAL is Float32. You can specify the datatype by setting the GXF_DATATYPE configuration option (Float64 supported currently)

Details on the supporting code, and format can be found on the GXF-3 page.

NOTE: Implemented as gxfdataset.cpp.
