KML or GPX sync with pictures MacOS

[zierbeek]

Thanks!

So no adjustment.  Some pictures between others do not get a geotag assigned. is this expected. They fall in between images on the same day and about the same timestamp which get a geotag assigned.

Try geotagging these images again, but use the -v option.  This should tell you what the problem is.  My guess is the fixes in the GPS track are too far apart, but this can be fixed by adjusting the GeoMaxIntSecs and GeoMaxExtSecs API parameters.  Something like this:

exiftool -api geomaxintsecs=7200 ...

Thanks Phil, will try that. Now i edited them manually in Digikam, not that big of a pain in the ass :p

Hmm
is there a syntax error in this? I navigated to the folder where my pictures are and also put a logs folder in there with the KML's

exiftool -api geomaxintsecs=15000 -geotag /Volumes/tank1/Photoprism/Photos/2019/07/logs/* /Volumes/tank1/Photoprism/Photos/2019/07/*

I get the error that it's to far beyond. Should i increase the geomaxint?

Try adding the -v2 (-verbose) option as described in Troubleshooting Geotagging #3.  The output will show you what time range the geotrack is using and what time is being used for the image.  In most cases you would just add the geosync option to shift the timing to match.

For example, normally I'm West coast US, -07:00 time zone currently.  But if I took a trip to New York, East coast US, -04:00, took pictures and geotrack, and tried to geotag when I got home, exiftool would be applying my local time zone of -07:00 by default and the files would be off.

So, in this example, it shows that the GPS track is at noon UTC, but the time set for the file is 15:00:00 UTC.  If I set -geosync to subtract 3 hours, (my -07:00 timezone minus the locations -04:00 timezone, e.g. -07:00-(-04:00)=-03:00) the command works.

I thought I would succeed this time but unfortunately not...

I went on a trip to Romania which is a one hour difference with my country. Belgium is UTC+2 and Romania UTC+3. The camera was set to Belgium. The kml I have is on UTC+2. I thought it should work this way:

Code Select Expand

exiftool -GeoSync=-01:00 -geotag *.kml /Users/matthias/Desktop/Roemenië\ 2021/


but no luck:

Warning: No writable tags set from /Users/matthias/Desktop/Roemenië 2021/DSCF7481.JPG

The kml was taken with google timeline and 4g was enabled all the time to improve accuracy

You need to geosync from the camera time, which you say is +02:00, to UTC.  So it should be -02:00.

As I said, add -v2 to the command and exiftool will tell you what time it is actually using and make adjustments based upon that.

Around 250 images get edited, 2300 don't get tagged.

Setting new values from /Users/matthias/Desktop/Roemenië 2021/DSCF7827.RAF
  Geotime value:   2021:09:13 11:11:59.000 UTC (incl. Geosync offset of -7200.000 sec) (local timezone is +04:00)

[StarGeek]

So the file DSCF7827.RAF using a time of "2021:09:13 11:11:59.000 UTC", adjusted by your computer's local timezone of +04:00.  Take a look at what DateTimeOriginal is set to in the file and figure out what time you need to set it to to be part of the geotrack and GeoSync based upon the difference.

thanks again for your help.

It seemed that it was a syntax error!

works:

Code Select Expand

exiftool -v2 -GeoSync=-02:00:00 -geotag "*.kml" /Users/matthias/Desktop/Roemenië\ 2021/*

doesn't work:

Code Select Expand

exiftool -v2 -GeoSync=-02:00:00 -geotag *.kml /Users/matthias/Desktop/Roemenië\ 2021/*

[Phil Harvey]

Yes.  MacOS and Linux will expand *.kml on the command line unless you put it in quotes, and the -geotag option requires a single argument so expanding into multiple file names doesn't work.
