Maybe this is a little bit offtopic here, but probably some of you can give me a hint. As mentioned in "[Gpsbabel-misc] Wintec WBT-201 ( G-Rays 2)" I would like to write GPS-data with exiftool and a bash-script. At the moment I am unsure if it works already with the last cvs-version 1.3.4-beta20070415, but.I would like to think about, what I need next. Probably I do not need to write a code myself. What does already exist for syncing the GPS-data with photos? The biggest problem I see for correct syncing is the time. It is impossible to have the same time at the camera(s) and at the gps-tracker. There is always a time shift. Also there is the timezone-problem. The time in the pictures, written by the camera, is the local time normally, while the time of the gps-tracker is UTC. Assuming, I have a text file, I don't know a good solution how to sync by using grep, cut or awk. It is unlikely, that the time in seconds corresponds. Normally there is no need to compare seconds, since the postion changes not very much, except you are in a fast car or an airplane. Thank you for any info. Al |
