[OSM-talk] Filtering GPX tracks when they're good enough to make ways from but contain too many points

[Beau Gunderson]

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
