Geotagging Pictures under Linux

How to batch geotag photos on Linux machine?
Firs you need to get the track log from your GPS device. I use "gpsbabel" with GUI (gpsbabel -t -i garmin -f usb: -o gpx -F /home/your_login/your_path/route.gpx).
Than I use "gpscorrelate-gui". Only you need is pick the track (in .gpx format) and pictures you need to geotag. Don't forget entering correct time-offset (based on timezone) and calculate day-light-saving! And push "Correlate Photos".
Easy like that.
