Hello Daniel, Hi Daniel,
I wrote a program (osmunda) that scans a GPX tracklog for maneuvers that are 'impossible' according to the given OSM data. There's a reasonable description of it in the 'routing' archive of August 2008. It's part of gosmore. Do an SVN checkout of one of the August / September versions if you want to give it a try. I know Gary68 has a tool for searching for routing irregularities, but at some point, I'd like to implement a better one : For each node a Calculate an, the location 10 meter North of a. If the route between a and an exceeds some threshold, flag the node as suspect (e.g. maplint). Repeat for other directions (s, w, e). Regards, Nic
