Error: GPX without temporal references

[koomot]

Hello, I would like to create a GPX track from a series of photos that are already geolocated (taken with my iPhone) and then use this track on Lightroom to geolocate other photos taken with a DSLR camera.

I followed this procedure:

- In the command line, I navigated to the folder where I placed the photos and copied the gpx.fmt file.
- I executed this command:

Code Select Expand

exiftool -fileOrder DateTimeOriginal -p gpx.fmt -d %Y-%m-%dT%H:%M:%SZ . > out.gpxThe generated file does not contain date information, so I can see the track but without temporal references.

In fact, for all files, I received this error:

Warning: [Minor] Tag 'gpsdatetime' not defined - ./IMG_3078.jpeg

What can I do? Am I doing something wrong?

Thank you!

[StarGeek]

The gpx.fmt requres the GPSDateTime tag in the image files. You can copy the time stamp from DateTimeOriginal but you also need a time zone so the adjustment to UTC can be made.

Run this command on one of the files and see if the time zone is included
exiftool -SubSecDateTimeOriginal file.jpg

If the time zone is included, then you can use this command to create the GPSDateTime tags, changing the double quotes to single quotes if you are on Mac/Linux
exiftool "-GPS*Stamp<SubSecDateTimeOriginal" /path/to/files/

If the time zone isn't inlucded, then you would have to add it either by including it in the command (changing ±00:00 to the actual time zone where the image was taken)
exiftool "-GPS*Stamp<${SubSecDateTimeOriginal}±00:00" /path/to/files/

Or you could add the time zone to the files first, then use the first command.
exiftool "-OffsetTime*=±00:00" /path/to/files/

The -d %Y-%m-%dT%H:%M:%SZ of your original command can be dropped, as the gpx.fmt will ignore it and correctly format without it.

Thank you very much, it works perfectly.
I added the time zone, and then I created the GPSDateTime tags.

How can I do the same with videos in MOV format? Is there a way for those too?

[Phil Harvey]

The "Usage" line in gpx.fmt shows how to do this for video files (assuming they contain timed GPS information):

exiftool -p gpx.fmt -ee3 FILE [...] > out.gpx

[koomot]

Thank you for the reply, but I'm afraid I didn't understand.

My MOV files have the same issue as the photos; the same warning appears:

Warning: [Minor] Tag 'gpsdatetime' not defined - ./IMG_3838.mov.

While StarGeek's solution resolved the issue for photos, it didn't work for videos.
How can I add the time zone and create the GPSDateTime tags to the MOV files?

[koomot]

I add that when I run command exiftool -SubSecDateTimeOriginal ./IMG_3838.mov
I receive this as a response: Warning: [minor] The ExtractEmbedded option may find more tags in the media data  ./IMG_3838.mov

[StarGeek]

SubSecDateTimeOriginal doesn't apply to videos.  Make sure you have the original unedited gpx.fmt file for them.

Copy/paste the entire command and output from when you try to extract the data from a video so we can see everything that is happening.

The generated file does not contain date information, so I can see the track but without temporal references. Why does this happen?

[Phil Harvey]

Maybe try adding the -extractEmbedded option.

I can see the track but without temporal references.

How do you see this?  Use ExifTool with the -extractEmbedded option and no other options to see what this file contains.

- Phil

[StarGeek]

When I use this command:
exiftool -fileOrder DateTimeOriginal -p gpx.fmt  . > out.gpx

You dropped the -ee3 (-extractEmbedded3) option that is listed in the gpx.fmt and in Phil's first post in this thread.

Yes, it seems iOS ~13.2.2 and later do not have GPSTimeStamp anymore, only GPSDateStamp, and the GPSTimeStamp offset is moved to OffsetTimeOriginal, OffsetTime, and OffsetTimeDigitized tags.

So you have to copy and add GPSDateStamp to the images using those OffsetTime* tags.

I guess OffsetTimeOriginal is most important because apps like Photos.app ignore the rest.

So maybe the config .fmt files could be updated to read also the OffsetTimeOriginal tag in addition to GPSTimeStamp?

Use ExifTool with the -extractEmbedded option and no other options to see what this file contains.

With that command I get this result:

You dropped the -ee3 (-extractEmbedded3) option that is listed in the gpx.fmt and in Phil's first post in this thread.

Unfortunately, even with this option the result is the same

So you have to copy and add GPSDateStamp to the images using those OffsetTime* tags.

"How can I do this? What command do I need to give?"

So maybe the config .fmt files could be updated to read also the OffsetTimeOriginal tag in addition to GPSTimeStamp?

How is it possible to do it?

"How is it possible to do it?"

"How can I do this? What command do I need to give?"
See the comments above.

"How is it possible to do it?"
That was just an update request. Sorry for hijacking the thread 

[StarGeek]

The "Usage" line in gpx.fmt shows how to do this for video files (assuming they contain timed GPS information):

exiftool -p gpx.fmt -ee3 FILE [...] > out.gpx

- Phil

This is the command you dropped -ee3 from in this post of yours.

We already know you don't have GPSDateTime values in your GPX file.  We need to see if they are actually in your video files.
