Degrees and hemisphere (example: 44.50416 S)
Signed degrees and minutes (example: -44 30.2500)
Degrees, minutes, and hemisphere (example: 44 30.2500 S)
Signed degrees, minutes, and seconds (example: -44 30 15.000)
Degrees, minutes, seconds, and hemisphere (example: 44 30 15.000 S)

Clear point edit fields after reference point addition/replacement – when enabled, the Point Name, (Across) X, (Down) Y, East, and North input fields will be cleared after adding a new point or replacing an existing one.
Save text report when reference information is saved – when enabled, a .txt file containing all reference information (point list, coordinate system, solution maximum and RMSE values) will be saved along with the reference file.
Clear reference point list when new source image is loaded – when enabled, loading a new source image will clear the existing point list. When disabled, the existing point list will remain and be applied to the newly loaded image.
