Comment 1 for bug 1989024

First there are several GPS tags (e.g in Exif and/or XMP) possible.
Second some GPS tags are indicating a direction and would be wrong in the final panorama.

But the tags which are copied into the final panorama are customizable.
Go to preferences, tab Stitching (2) and add the necessary tags to the final Exiftool arg file.

If your images have the GPS info in the exif tags, you will probably need:
-GPSLatitude
-GPSLatitudeRef
-GPSLongitude
-GPSLongitudeRef
-GPSAltitude
-GPSAltitudeRef
-GPSMapDatum
-GPSDateStamp
-GPSTimeStamp

If you don't have direction GPS tags, maybe also
-GPS:all
will work. But this is untested.
