Import GPS data from log files as a XMP file instead of modifying RAW image

[imajica]

I know I can import GPS data from a log file, but is there a way to add this GPS data as a XMP file instead of modifying the original RAW image?

I am using the GUI version of ExifTool.

I can't speak for the GUI, but from the command line this may be done by adding -srcfile %d%f.xmp to the command.

I would try this.

First select the xmp files. Not the raw!
Export/Import, Import GPS data from log, Log files
Select the GPS file.
Execute

This is not what I mean.... I have Raw files in CR3 format.  My GPS log file was created as a GPX file.  I can use the GUI to merge the GPS data from the GPX file, but it modifies the CR3 file.  I want it to create a XMP sidecar file instead.

Someone else mentioned how to do it via command line ... I will give that a try.  Am just hoping that it is possible via GUI.

Ok. I thought you already had XMP files.

Edit: You can create XMP files in GUI using Export/Import, Export metadata into, XMP files.

Good luck

Thanks.

I don't want to export the data... I want, as part of the import process, to create an XMP file with the GPS data as it reads the data from a log file.  I don't like the idea of it modifying the original files.

I think we have a misunderstanding.

This function, can create XMP SideCar files from RAW files.(Like CR3)


You can see from the sizes it does not include the image.


And yes, you can use multi-select.

This is my understanding of the desired operation:

1. ExifTool reads the GPS from a .gpx log file

2. ExifTool reads the RAW file to get the timestamp

3. ExifTool writes the appropriate GPS coordinates to the xmp file.

From the command line it would look like this:

exiftool -geotag FILE.gpx "-xmp:geotime<datetimeoriginal" -ext cr3 -srcfile %d%f.xmp DIR

And that is something that can only be done in GUI using ExifTool Direct:

That did the trick...

And is there a way to have it use whatever gpx file(s) is in a folder without having to give it a specific name or to rename it in the command line for every different GPX file I have.  Sometimes I want to geotag photos from multiple days which were recorded as multiple GPX files.

And while I do not need to now, if i want to do a GPS time offset, how can that be done from the command line.  Sometimes when I travel, I do not download my photos until I get home and the photos were taken in a different timezone. or I forget to change the time on my camera right away after DST.

Thank you.

Not to take away from FrankB's excellent work, but you might want to try GeoTagNinja, which uses exiftool to write the data.

It has a setting to "Process the image file itself" and won't process RAW file types by default

You can do this in the command: -geotag "C:/FOLDER_NAME/*.gpx"

edit: Missed it by *that* much

You can use a wildcard to use all the GPX files
-geotag *.gpx

See Example #11 on the "Geotagging with ExifTool" page.

See the -geotag option, paragraph starting "Multiple GPS log files"
