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