I would like to make some plots of the travels I logged. Maybe
there are better programs to do this with, but I like it simple:
GNuplot by default likes datafiles that contain whitespace separated
My GPX file contains:
<trkpt lat="52.065627000" lon="4.823633000">
so, I'd like a format that holds lines like:
1246373966.123 52.065627 4.823633 3.9 94.82
(Oh, optional feature for this format should be to have say
# 52.064933 4.820421
as the first line, being the first point on the track.
Next all position information will be in meters relative to this
Hmm. Thinking a bit more about this. How about interpreting a
printf-like format string for each datapoint? My suggested line would
%s %n %e %h %S
(s for date-in-seconds, %n for lattitude with north positive, %e for
longitude with east positive, %h for heigth-in-meters %S for
speed-in-km/h, %s %w are obvious. Speed should get m/s and mph as
units as well.)
With over 140 formats already supported, I expect that making another
output-format-plugin for gpsbabel is a piece of cake.
Does such a module already exits?
Does anybody volunteer to make it?
Otherwise, if you plan to incorporate it into gpsbabel I'm willing to
write it. If it isn't going to be included I'll stick to making a
quick script or something like that.....

Does it sit on the couch all day? Is it unemployed? Please be specific!

The tabsep format outputs everything we know into a tab-separated format.

We have a much more complete scheme that allows non-programmers to create
their own something-separated files.
