Objective:
I have a grid (*.grd) in my Geosoft application I would like to convert into an RGB GeoTIFF.
Resolution:
- Display the grid to a map by going to Grid and Image > Display on Map > Grid.
- Select the grid in the Map Manager by clicking on the group. This will draw a selection box around the grid.
- Export the grid to a GeoTIFF by going to Map > Export
- Set the Output Format to GeoTIFF (*.tiff)
- Set the Region to Export to Selection.
- Under Image Raster Resolution, click the Grid button.
- Press OK
Notes:
Blank / empty cells in your grid will be exported as white with an RGB value of 255,255,255.
The grid and GeoTIFF will not line up perfectly, due to slight changes in resolution, but it should be pretty close.
