At any point the current workspace can be saved using the "Save workspace..." menu command. This writes the stations, loops, and surveys of the campaign, along with their checkbox states, drift method(s), delta-g's, and datums, to a file with a *.gsa extension. The file is written in JSON format and can be read using a text editor. Hand-editing the file, however, will likely lead to errors. Adjustment results are not saved. Saved workspaces can be imported using the "Load workspace..." menu command.
