Filtering GPS points

Jan 2, 2010 at 9:02 PM

I’ve been testing today and found a lot of GPS noise in de GPX file. This is normal. I filtered the GPX file with “Prune” (http://wiki.openstreetmap.org/wiki/Prune)

The original file had 212 points.

167 points were duplicates

7 points could be deleted because they were very close

1 point was a “wacky point”, the reason why I wanted to filter. It was just 1 point 1.9km completely of route.

 

The result was a clean file with 37 points.

I would be very nice to have such filters onboard…

(I have both GPX files available)
