Yes I did, it's as frustrating as all the examples at http://openlayers.org/dev/examples
All the lat, lon and zoom are always hardcoded. Not dynamic as I need it. So not helpfull. Please find a screenshot of what I did using shell and perl scripts I wrote today and gpsbabel: >From thousands of lines like this: 1244296533 1 8.664075 49.993945 172.012836 to this: http://mybestprojects.com/data/test3/Skytraq-Venus_6-GPS_tracks.png Nice eh? Now how to make this zoom working?
