[OSM-talk] gpx tool advice needed

[Tanveer Singh]

Hi,
I have a lowrance GPS.
This has the option of dumping data to SD card.
What it will do is dump all the trails to SD card under 1 file <filename>.usr
Then I use GPS Babel to convert usr to gpx.
But this gpx is huge.
Is there a way to extract just one trail out of this gpx data and keep
the timestamps intact
All trails have different names, and when I convert to kml I can see
the tracks individually.
Is there a way where I can do
1. Big .usr file to big .gpx file
2. Extract one track and save to a small gpx file which I can upload to osm?
