When also downloading the raw tracks from the server, it seems
as if nodes that don't belong to one track still are connected
and are shown as one way.

This leads to many connections that criss-cross the area.

This is down to the way that the points are downloaded, and the fact that there is no way to be able to tell from the API where one track stops and the next starts.

Is there an option in your app to not draw lines between the points?

Would it be sensible to assume that those points that are located on the
bounding box are endpoints of their respective tracks?

That will reduce the problem, but won't work for tracks that stop or start in the middle of the bbox.

This preference could be the maximum length that will be drawn: 0m for no connections at all, 100m for connections between node that are closer than 100m.

I implemented the on/off switch of displaying track segments for now. If someone feels dantje solution should be implemented, please reopen.

I commited a patch (r11030) that uses a fixed threshold of 100m.
