This could be fixed by some data cleaning SW, I suppose, but it should be taken into account.
As far as I remember, JOSM by default does not support snapping to GPS nodes exactly for these reasons. Cheers, Igor -- http://igorbrejc.net _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/dev
