The Golden Software Grid filter imports and exports two-dimensional uniform lattices (elevation grids) in the Surfer Grid file format. Both ASCII and binary variants are supported.
File Description
The Golden Software Grid filter imports and exports two-dimensional uniform lattices (elevation grids) in the Surfer Grid file format. Both ASCII and binary variants are supported
Files with the .GRD extension are Surfer grid files. To preserve faulting information and to use double precision values, be sure to save the grid in the Surfer 7 format. If you need to use a grid in Surfer 5 or Surfer 6, save the grid as GS ASCII .GRD or GS Binary .GRD. Keep in mind that these two formats do not retain fault information or double precision values.

Export Method
Select a lattice or image module and choose the File | Save Data command.
Select one of three encodings for the export file:
Export Restrictions/Limitations
Choose the File | Save Data command to export a uniform lattice to the Surfer Grid format. The exported lattice has a "z" dimension of one, i.e., the lattice is two-dimensional. If an input lattice with a z dimension of greater than one is exported, then Voxler prompts the user to save multiple slices into separate .GRD files.
If a multi-slice uniform lattice is output to a .GRD file format, it is output as a series of slices in the Z direction. The Select Slices dialog appears and the user is prompted for the range of slices to output and a file name template that adds the slice number to each generated file name.
