Golden Software ASCII Grid (*.grd)

This is the ASCII-based (non-human-readable) version of one of the raster formats used by Golden Software products (such as the Surfer series). Cadcorp SIS Desktop supports this format for both reading and writing (including create, delete and copy). Currently the associated formats for colour, metadata and symbols are not supported.
