Last year, a changeset was submitted which fixed the golden software 6 file formats (10814), but unfortunately it wasn't applied to the surfer 7 file format which has the exact same issue.<br><br>This can be fixed by replacing the GetGeoTransform method in frmts\gsg\gs7bgdataset.cpp with the attached snippet.
<br><br>I've also submitted this as ticket #2132<br><br>Thank you,<br>Reed Copsey<br><br><br><br>
