mats

Note that very long tracks may be subject to clock drift, as GPSBabel does not take into account the amount

of time it may take to write the NMEA sentences. Also, there is no guarantee that it will pause for exactly

the specified number of seconds between samples; different operating systems will allow greater or lesser

precision for timers, so actual precision may be as much as plus or minus 100 milliseconds.

If you are using this option with compressed or simplified tracks from your handheld GPS receiver, you

might find the interpolate filter useful.

append_positioning option

Append realtime positioning data to the output file instead of truncating.

When writing NMEA realtime positioning data, append to the output file instead of truncating it on each

successive position fix.

baud option

Speed in bits per second of serial port (baud=4800).

To the "nmea" module, the "baud" option specifies the baud rate of the serial connection when used with

the real-time tracking option.

OziExplorer (ozi)

This format can...

• read and write waypoints

• read and write tracks

• read and write routes

pack option

Write all tracks into one file.

In normal case GPSBabel creates for each track a separate file (track.plt, track-1.plt, ...). With this option

all tracks will be written into one file. A '1' in the third field of the trackpoint record signals the beginning

of a new track.

gpsbabel -i gpx -f tracks.gpx -o ozi,pack -F track

snlen option

Max synthesized shortname length.

snwhite option

Allow whitespace synth. shortnames.
