<> == GPX fiddling == See [[GpxSplitter]], a program I wrote for splitting multiple GPS tracks from a monolithic GPX track file. === Remove low accuracy GPS points === {{{#!highlight sh numbers=off # Remove low accuracy HDOP gpsbabel -i gpx -f in.gpx -x discard,hdop=3 -o gpx -F out.gpx # Remove low accuracy HDOP and VDOP gpsbabel -i gpx -f in.gpx -x discard,hdop=10,vdop=20,hdopandvdop -o gpx -F out.gpx }}} === Reduce resolution === If a GPX file is too large, run this to reduce the number of points in the file. Removes points within 0.1m of each other (i.e. standing still). {{{#!highlight sh numbers=off gpsbabel -i gpx -f in.gpx -x simplify,error=0.0001k -o gpx -F out.gpx }}} === Convert KML to GPX w/ gpsbabel === {{{#!highlight sh gpsbabel -i kml -f in.kml -o gpx -F out.gpx }}} ---- CategoryCheatSheet
