How does exiftool handle GPS DMS rather than decimal?

[eco]

Hi everyone,

I am using Python to to pull GPS data out of a Lightroom database and insert it directly into the file using Exiftool of course!

The data is presented in the database as follows:

Code Select Expand


exif:GPSLatitude="45,33.7893333333N"
exif:GPSLongitude="73,34.7643333333W"

I tried the following with and without '-n' and I get the same coordinates:

Code Select Expand


$ exiftool -ignoreMinorErrors -overwrite_original -preserve -gpslatitude=45.563155555555 -gpslongitude=-73.579405555555 myfile.jpg

The actual Python list looks like this:

Code Select Expand


('-ignoreMinorErrors', '-overwrite_original', '-preserve', '-gpslatitude=45.563155555555', '-gpslongitude=-73.579405555555', 'myfile.jpg')

Instead of being in Canada, I end up in ‎⁨Jambyl⁩, ⁨Kazakhstan⁩

I suspect it has to do with N,S/E,W but I am not sure how to handle this with Exiftool. West and South seem to be translated as Negative numbers when in decimal degrees. Can Exiftool handle this or should I start using regex to find cardinal direction?

Any help is appreciated.

Thank you all!

@Phil, thank you for helping me manage my photo library!

After a bit more digging I am seeing the following:

Code Select Expand

$ exiftool -ignoreMinorErrors -overwrite_original -preserve -gpslatitude='29.952294444445' -gpslongitude='-90.083705555555' myfile.jpg

Code Select Expand

$ exiftool /myfile.jpg -gps:all -a -g1
---- GPS ----
GPS Version ID                  : 2.3.0.0
GPS Latitude                    : 29 deg 57' 8.26"
GPS Longitude                   : 90 deg 5' 1.34"

I see no Cardinal information so it looks like the minus sign of the longitude is not taken into account. I suspect I am making a mistake here but I can't see what it is. I've been at it for too long!

I think that reading FAQ 14 should answer your questions.

... after all, we want you to stay in Canada.

Hi Phil,

Thank you for your help. My trip to Canada was a great one.

I hesitated putting the question in the Newbies section. I shouldn't have.

Thanks again!
