geotagging from a GPX file

Post by vkfoto »

With my Canon R6 and Gaia GPS I went for a walk taking pictures, both RAW and JPG, while recording my path.
Exported a GPX file and in the GEO tag panel, I tried to tag the pictures.
The activity bar on the lower left jumps up momentarily but no GPS coordinates are written to the pictures, neither the CR3 nor the JPG images.
Using the same GPX file, GPicSync has no issue writing the GPS coordinates to the JPG image but ignores the CR3.

I used to have a Solmeta tracker that would write the GPS coordinates in camera but unfortunately it has stopped working so I'm looking for an easy solution to Geotagging my pictures

Works for me, my e-bike camera has time but no GPS, so I download the GPX file from my phone which has GPX data.
I select the pictures to have GPS data added, load the GPX track file and make sure time/date matches the images, then the icon "GPX Track" will appear on the bottom line of the GPS pane to the right, click this and the selected files will have the GPX data loaded assuming that the time data matches - if the camera clock doesn't match the GPS file you need to adjust the offsets by clicking the start/end, time/dates to correct the problem.

Doesn't seem to work on my system.
I can load the GPX track. Set the time to be in the image range. Select one or multiple images and click on the Apply button at the bottom of the GEO tag panel. The activity bar at the bottom left of the screen pops up momentarily. No GPS coordinates are added to any image.
Is a Google API key needed for this to work? Not doing any lookups just applying data from my GPX file to image so i would not think so...
Since the same GPX file data can GEO tag the same JPG images using GPicSync, I don't suspect the data unless PSU is picky about the source of the GPX data. Mine comes from an exported Gaia GPS log file.

Works for me for jpg or cr3 files from R6. Load a GPX track created with Oruxmaps, select a file, press GPX point and, then, apply, and coordinates are stored to the file.

By the way, I would suggest to use a Cannon Camera connect app. When a picture is taken it sends current GPX data to R6 via bluetooth, and they are stored to a cr3 file.

OOPS, I seem to have skipped a step in my previous tests, didn't press the GPX point before pressing Apply. Since there was a sort of Activity in the lower left, I didn't see that I was missing something.
Now to start tagging.

Hi, I also had issues with geotagging from GPX files, but I found that ensuring the timestamps in the GPX file match the images' timestamps helps a lot. Maybe checking your camera’s clock and syncing it with the GPX file could solve the problem.

I could set my camera to GMT since that is what the GPS tracker uses but then I would have to constantly convert to local time to sync with local events.
Still have to give this idea a deeper think

It's easy to apply an offset in the GPX pane, and this can be used either to compensate for camera clock drift*, or for GMT / local time mismatches, or both - but trying to work out the correct amount (and even direction, ie should it be a plus or negative offset within the context of the PSU dialogue) used to drive me crazy!

I did a long post about it once, somewhere on this forum, but there are a number of equally valid ways of tackling it and I never did find a really hassle-free way of doing it.

*My cameras' clocks drift by a significant amount. I could reset them regularly but as I always forget** I created a spreadsheet that would take the offset at a last known point (from a photograph of my phone's clock), calculate the rate of drift, and give me the offset I should enter for any given date. But it's a pain.
**I always forget to adjust for DST and for local time too, so I keep them on GMT/UCT permanently.

I found the thread FWIW: viewtopic.php?t=27508&hilit=gpx

It's from 6 years ago so parts of it may no longer be relevant - PSU has moved on and the windows phone referred to that I was using at the time is now a long forgotten piece of tech history :) !

And as mentioned previously there are many ways of approaching this in terms of applying the offset, whichever works best for you.
