Using exiftool
, if I have a file named foobar.jpeg
and the shell variables lat="37.7708"
and lon="-122.451"
.
What command do I use to set the EXIF metadata for that jpeg file such that its "geotag" / GPS metadata is set with those coordinates.
exiftool "-GPSLatitude=$lat" "-GPSLatitudeRef=$lat" "-GPSLongitude=$lon" "-GPSLongitudeRef=$lon" foobar.jpeg
Because the GPS coordinates tags are unsigned, you need to make sure and assign the values to the relevant GPSLatitudeRef/GPSLongitudeRef
tags as well, especially if the location is in the Western and/or Southern hemisphere. Even though these values would normally be set with N/S
and E/W
, exiftool well accept the raw values and figure out the proper Ref direction from that.
