Ralf,
On januari 20st, you compared the original logfile to the file created by Twilight.
I think, this comparison has been done on the next version of Twilight?
About compression: In Memory Map, tracking can be limited with the following adjustable parameters:
1. Minimum distance between log-points
2. minimum time between log-points
3. Maximum number of tracking-points
If one drives in a straight line, you could store only 2 points. But if I make stops to take landscape-pictures, it would be nice to have the intermediate points also, to check the location of the picture later.
In what format will the compressed logfile appear? Till now, I convert the NMEA log-file with GPSBabelGUI to the .GPX-format, wich can be imported in Memory Map.
Your answer may be in German, I can't write in German, reading will do.
