SVN commit 587073 by cgilles:

kipi-plugins from trunk : new plugin to synchronize pictures metadata with a GPS data file.

First beta version of GPSSync kipi-plugin is now available for testing.

To use it, you need a GPX xml file generated by your GPS device. The GPX file must be generated to render a wayspoints or trackpoints list.

If your GPS device do not support GPX, you can generate it using GPSBabel program like this :

# gpsbabel -w -i mapsource -f Driveback.mps -o gpx -F Driveback.gpx  

The plugin use the Exif time-stamp to correlate GPS data. Accuracy of 30s is used to diff camera and GPS time-stamp. Of course, the date of your GPS device and your camera must be set properly (:=))).

That's a good point to use gpx as this is the only standard format and
more and more applications can use it...

 From my own experience, 30s is usually not enough. It would be great to
be able to change it manually.
When I synchronize my pictures and my gps track, I use a 2 minutes
delay, which is enough for me (there is no new point in gpx file when I
stop to take pictures :) ).

Please, also note that times in GPX are GMT, so we also need an offset,
depending on the timezone.

Congratulations for this work !
