[Openstreetmap] Simple gps track format?

[Alex Vieira]

Hello,

If you have access to the raw NMEA messages that come from the GPS you can log 
these and gpsbabel will understand them.
An NMEA message looks like this (there can be other sets of 5 characters in 
the begining):

$GPGGA,212301.715,5202.2738,N,00418.1869,E,1,06,1.5,47.9,M,47.1,M,0.0,0000*48

And you can convert it to GPX with a command like:

gpsbabel -i nmea -f <nmeafile> -o gpx -F <outputfile>.gpx

Greetings,

Alex
