Many of the roads on the map-link you posted have GPX traces, although some have a fairly low sample rate, such that it's not the easiest to join the dots. I would say in general that GPX traces are likely to be more accurate than NPE. If you know something is wrong, then I'd just go and change it, but I definitely wouldn't bother aligning loads of stuff to NPE if someone has been up there with a GPS. It might be worth asking whoever did the original mapping if they have any notes or photographs - perhaps they've interpolated between two known points to get some streets on there? Perhaps there are also GPX waypoints? Richard _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
