[josm-dev] geotagged images proposal

[Женя Деревянкин]

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 :(
