Thanks, Marko! I've tried gpscorrelate and it does what I need. The only issue is I'm not always sure about the time syncronisation. It's much easier to play with the time delta in a GUI app to set everything right. For merging GPX files I use gpsbabel:
gpsbabel -i gpx -f <input1.gpx> -f <input2.gpx> -f <inputN.gpx> -o gpx -F output.gpx and then gpscorrelate -g output.gpx *.jpg I'm taking photos using the same cellphone that logs the tracks - it's clock is syncronized with the GSM network. So it should be pretty exact. But anyway JOSM placed the images incorrectly, i had to rewind the time, up to 40 minutes sometimes, I don't know why. Maybe there was a bug in JOSM that saved the time difference from the previous session and automatically added it to the next one? The last time I geotagged photos a few days ago, there was no such thing and the images were aligned correctly right away, without adjustment. PS - upoloaded about a hundred geotagged images to OpenStreetPhoto yesterday, and they still haven't appeared on their slippymap. I believe the project is in a semi-dead condition. Too bad. I liked their idea :( -- best regards Eugen Derevyankin 2009/9/1 Marko Mäkelä <[email protected]>: > On Tue, Sep 01, 2009 at 03:01:14AM +0200, Martin Koppenhoefer wrote: >> I was using a separate script in windows for this (haven't yet managed >> in Linux but I guess it available as well), that was writing those >> coordinates into the images.
