Adding geotagging information directly to the XMP sidecar file?

[paperdigits]

My phone spits out GPX formatted GPS files and I'd like to add that information to the XMP sidecar files.

I've been trying to coerce exiftool to do such a thing, but I have not been successful.

The closest I think I've come is the following command:

exiftool -xmp:geotag=track.log *.nef -o %d%f.xmp

The -o doesn't seem to be compatible with using the geotag feature.

Any pointers would be helpful or if this just isn't possible without a script, I'll start working on that.

I would have thought that should work.  I don't have time to try it right now, but I will when I get a chance.

Thank you, Phil.

Interestingly enough, this does work on my Debian 8 (Jessie) computer, but was not working on my Fedora 24 laptop (which I've since reinstalled). Not sure what the problem is/was.

Is this the expected output when using the -xmp:geotag command? I thought it'd be using the XMP vocabulary, but instead gives the exif:

That is correct.  It is using the standard "exif" namespace of the XMP specification.

All I can think of is to check the version of exiftool running on your laptop.  If it is the same, then all signs point to operator error.

I'm perfectly willing to attribute it to operator error and I've since moved to Fedora 24, where I cannot replicate the error.

Thank you for your time!
