Good evening,
GeoSetter has written the wrong GPS data to some of my files. What is the cleanest and easiest way to delete ALL GPS-related information for an image? I have searched the forum but could not find an answer.
Many thanks in advance and best wishes

Hi Hermann-Josef,
To delete all EXIF GPS, do this:
exiftool -gps:all= FILE
If it may also be stored in XMP, it is a bit trickier, but this command should handle both cases:
exiftool "-gps*=" FILE
where FILE is one or more file and/or directory names.
The first command does a block delete of the EXIF GPS directory (quick and clean). The second command individually deletes all writable tags with names beginning with "gps" (slow and messy).

They mention Geosetter and Geosetter does set the XMP-exif geo tags, so the second command will have to be used.
Good evening,
thanks for both replies!
Yes, the second one has to be used. I first tried to remove the GPS information in EXIFtool GUI, but that was not the full story. With the second version Phil mentioned all gps-information is gone.
Best wishes

I am trying to delete GPS from a .mov file but nothing happens:
$ exiftool -gpsaltitude IMG_1234.MOV
GPS Altitude : 93.729 m
$ exiftool "-gps*=" IMG_1234.MOV
0 image files updated
1 image files unchanged
$ exiftool -gpsaltitude= IMG_1234.MOV
0 image files updated
1 image files unchanged
$ exiftool -gps:all= IMG_1234.MOV
0 image files updated
1 image files unchangedDoes anyone know what I am missing here?
ExifTool has only limited write ability in MOV videos, and currently can't write/delete these tags.

You might try FFMpeg. Here's a StackExchange (https://unix.stackexchange.com/questions/339119/how-to-strip-gps-location-data-from-an-mp4-video-file) question about removing GPS data from an MP4. It should be the same procedure for a MOV file, though you should test it first.

$ exiftool --help | grep MOV
CRW r/w | HDP r/w | MOV r/w | PMP r | VSD rman page lists MOV as r/w with no restrictions.
But if you view the whole thing, there are restrictions on the types of metadata below that.
If the tag was XMP:GPSAltitude, exiftool would be able to edit it. But odds are the tag you're looking at is Composite:GPSAltitude. Add -G1 -a to your command to check. That tag, in the case of a MOV file, is probably derived from either QuickTime:LocationInformation or QuickTime:GPSCoordinates (see Composite tags (https://exiftool.org/TagNames/Composite.html)). And if you check under Quicktime tags (https://exiftool.org/TagNames/QuickTime.html), you'll see that both of those tags are not writable by Exiftool.
