Golden Software Reference Files
If you have looked in a folder that contains data files created by Voxler, Surfer, or another Golden Software application you may have noticed files with a .GSR2 extension in the folder. These Golden Software Reference files are created when you save a projected data file from Voxler. For example if you create a data file, use the Data | Assign Coordinate System command, and save the data file as a Golden Software .DAT 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, Grapher, MapViewer, Strater, or Didger.. 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.
