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

Simplify way in JOSM does it (lowermost icon on the left toolbar, if memory serves me well).

Similarly, if you load the track directly into Potlatch (by clicking on 'edit' in the 'GPS Traces' page), you can then click the 'Track' button to convert it directly into a simplified way. Shift-click the button for higher resolution (less simplification). cheers Richard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

Ah, excellent! Looks like this is part of 'utilsplugin', I didn't have that installed previously. :) I upped the value of this knob on the Einstein page to 250 and got good results (the default in the code was 50): simplify-way.max-error Thanks, Beau On Fri, May 23, 2008 at 1:36 AM, Stefan Baebler [EMAIL PROTECTED] wrote: Simplify way in JOSM does it (lowermost icon on the left toolbar, if memory serves me well).
