Grid Compression

Oasis montaj features a grid compression option that enables you to reduce the file size and improve the performance of Geosoft grids files (*.grd). Processing speed is improved by compressing files because the computer takes less time to read and write to disk. Power users will especially benefit from using compressed grids.

The two charts below show the performance increase for an ASIG grid 10538x6560 pixels in size, and for a Geosoft Colour Grid 1747x1106 pixels in size.
