Golden Software Reference Files

If you have looked in a folder that contains data, boundary files, or grid files created by Surfer, you may have noticed files with a .GSR2 extension in the folder. These Golden Software Reference files are created when you save a projected file from Surfer. For example, if you create a data file and use the Data | Coordinate System | Assign Coordinate System command, when you save the data file, you will see both the filename.dat and filename.dat.gsr2 in the directory.

The Golden Software Reference files contain the projection settings used to project the data in Surfer. Projection, datum, and georeference information are stored in the .GSR2 file. When you create a map from data or a grid that has an associated .GSR2 file into Surfer, the projection information is used when displaying the map. If the Golden Software Reference file is deleted, the boundary can be imported but it will not be projected properly.

Surfer .SRF file format retains all of the information in a map, including projection information.
