Geosoft Grid Files

Grant Boxer

QGIS does not seem to be able to read the Geosoft grid format (*.grd) grids.

Can anyone suggest how I may be able to convert these files to a format (for example to ERMapper (*.ers) files) suitable for QGIS?

Hi,
According to this the geosoft free viewer has some export capabilities.

Good luck
Nicolas

Re: Geosoft Grid Files

Hi,
indeed, Oasis Montaj free viewer is able to convert .grd to .ers, from under Grids menu.
I successfully exported a .grd file as .ers, and while my Qgis is busy processing, I was able to open
the exported .ers in Global Mapper.
Tried to attach a screenshot of the output format choices, but it gets blocked due to message size.
regards,
Szilard

Hi,

Although the .grd format used by Geosoft nowadays is proprietary, you can use the free viewer, as said below, to export the file into .gxf (the Geosoft grid exchange format) and open it in many, many applications, including QGIS.

A word of caution: you must be sure that the orientation of the Geosoft grid is set to 1, otherwise the GDAL GXF importer will not work correctly (at least, as at the last time I've used it, long time ago!).

cheers,
Benoit
