I have captured photos with gopro as usual.
When I match photos with GPX track in JOSM (with auto-guess) and compare if position is OK (ortophoto, cadastre). If not, I try manual adjust ±1-2 second.
Position of sequence was OK, so I just write coordinates and didn’t look to time shift closely.
Now date for sequence is jan 2, 2013 but in reality it is may 6, 2017. ![]()
It is possible somehow offset time? Or better delete bad sequences and upload with corrected time?
Thanks
