I've succeeded in uploading a large portion of my GPX tracks from Mexico & South America and now would like to map out some of the highways.
In many portions the GPX track (when converted to a data layer) is good enough for a way--the only sticking point is that there are way too many data points. I tried osmtrackfilter.pl with '--filter-reduce --out-raw-gpx' but the resulting file is actually bigger and doesn't seem to remove any points. Anyone know a filter that does a good job of achieving a large decrease in points without altering the shape of the track too much? These have got a lot of very straight portions and osmtrackfilter.pl was supposed to do a good job with those... Thanks, Beau
