Tagging Native 3FR or FFF Files in Mac OS

[o2mpx]

Does anyone know of a Mac OS application that can take a .gpx file, and tag either 3FR or FFF files with the GPS coordinates?

Found a couple of taggers, HoudahGeo/Geotag Photos Pro 2, but they don't work with HB file formats. Phocus doesn't appear to have a way of taking a .gpx file and applying the coordinates to their photos either.

I use Graphic Converter,
https://www.lemkesoft.de/en/products/graphicconverter
a image -viewer /  -organizer / -converter  made in Germany.

You can load a gpx-file (a track that has been recorded with a GPS-App) by right-clicking on it inside GraphicConverter, load it, and then select the FFF files and tag them with GPS coordinates. Or you can tag files using a map (Apple/Google) to find a location.

The software costs around $40 and is quite powerful...

If you want to try Graphic Converter, it is better to download it from their website - not from the appstore, because the appstore version has a number of restrictions and less functions.

...if you use the latest Beta version of GC

loading a gpx-track is easier than before:

If you have saved it to the same folder like where your fff files reside, just rightclick on it and choose "open GPX/NMEA file..." and it gets loaded to use it on fff files:

Select them, rightclick on one of them and choose "GPS" and then "GPX/NMEA der Auswahl zuweisen ..." (I use a German menu).
You will then be asked to choose the correct timezone, and the tagging will be done.

An icon will show up in thumbnail corners, to signal, that images have GPS coordinates...

@KuehnKvT many thanks for the application advise. Downloaded a test copy since it's available directly from site, stumbled around for 15min without reading the manual other than what you've provided, and successfully tagged fff files with coordinates. Sending money to buy the software.

Again, much appreciate the advise. Thank you.

...to make sure, you get precise locations in your tagged FFFs, it is a good idea to set the time in your camera exactly to the current time, before shooting images and before recording a gpx-track with a device.

...I use an Apple Watch "Ultra 2" to record the gpx tracks with the app "WorkOutDoors".

The watch uses a so called Dual Frequency GPS system, which delivers more precise GPS data than an iphone and it does this independently from the phone. I compared a track recorded by the watch with one recorded by my iphone: The watch's track was a lot better, had less errors in situations, when satellite-reception is not so good.
Contributing to a better precision is the better position of the watch on the wrist whereas the iphone may usually is carried at a belt...

I programmed the watch's Action button (left side) to start a GPS-recording using "WorkOutDoors".
To end a recording, long tap on the lower part of the screen and choose "End".
The track will be sent to the iphone, where the main part  of the app is.

Start the App and tap on the latest track in the list.
You can give the track a name and export it ("Export") as GPX ("Share GPX file") using Airdrop or Email or one of the usual ways.

On the MAC I save my GPX files from the mail app directly to the folder, where the Hasselblad FFFs will go.

In GraphicConverter I rightclick the gpx as described above, to load it.

@KuehnKvT Impressive! Will chalk up another reason to get an Apple Watch!

...but only the "Ultra"-Watches have the improved GPS-accuracy...
Otherwise a normal iPhone is enough to record a good gpx-track!
