What is the time tolerance when geotagging

[MtnBiker]

How near to the photo time does the gpx log information need to be.

And can that tolerance be changed?

I ask because I have a 20 minute gap in one log (phone shut off?) and I didn't move much during that time and just wanted to open up the tolerance for one batch.

I can think of other work arounds, but this one would work for this case.

Thank you

The GeoMaxIntSecs and GeoMaxExtSecs API options control how far ExifTool will interpolate/extrapolate in a GPX file.  Read here for a description of the options.

By default, GeoMaxIntSecs is set to 1800, which is 30 minutes, so ExifTool should treat your GPX track with a 20-minute gap as one continuous track.

Thank you Phil

I looked at another file and maybe the wrong time is being used. OM has these fields exiftool -a -u -g1 -s .../2024.09.17-14.52.53-35.gs.O.orf:

I have this track point in the log

 <trkpt lat="48.294398" lon="89.599159">
    <ele>2115.0</ele>
    <time>2024-09-17T07:53:23Z</time>
</trkpt>

The error I'm getting is this

Task Terminated with exit code 1

Is something else going wrong? I'm on macOS Sequoia and I have been having an issue with path to files in iCloud, so maybe a problem there.

I name the files based on the local time.

From the docs on geotime

If a value for Geotime is not given, it is taken from unformatted value of DateTimeOriginal for each image (as if "-Geotime<DateTimeOriginal#" had been specified)...

So, the track as a time of 2024-09-17T07:53:23Z, but exiftool is using the DateTimeOriginal of 2024:09:17 14:52:53, which does not include the time zone.

Try adding
"-Geotime<SubSecDateTimeOriginal"
as the SubSecDateTimeOriginal does include the time zone, which allows exiftool to adjust to the UTC time of the track.
