I have hundreds of GPS tracks. Some are uploaded in OSM, some I forgot
to upload. Some are clean, some are dirty, some are squiggly and some
are a big cloud of points pointing to my house.
Any advice on how to maintain/clean the tracks before uploading?

This is the script I use ($1 is input file, $2 is output file):
gpsbabel -i nmea -f $1 -x discard,hdop=2,vdop=3,sat=4 -x position,distance=1m
-x transform,wpt=trk,del -x polygon,exclude,file=area.loc -x
transform,trk=wpt,del -o gpx -F $2
On a slightly related note ... I just went to the gpsbabel home page and looked
at the features on the new beta release. Apparently it now supports the Locosys
GT-31 ( the GPStoGo model), which it didn't when I used it last May.
Just thought I'd pass that on.
