The magnetic and gravity grids are available in the following formats:

1. Geosoft OasisMontaj (*.grd, *.grd.gi) binary format

2. Grid Exchange Format (.gxf) (an ascii grid transfer format)

3. ESRI Spatial Analyst (.flt, .hdr) binary format

Hi @shahsamkit,

FME can read the Esri Spatial Analyst binary format, using the Esri .hdr Raw Raster reader. However, the .hdr files supplied with the data seem to be missing a few entries required by the reader to define the data type.

If you add the following entries to the Ascii .hdr file, the data will read correctly:

pixeltype float
nbits 32
