Yup. Actually the real issue is mapping tolerances. On the UK canals, every inch counts in lock length. There are locks that our 71ft 6in boat won't get through, but would if it were a few inches shorter. And there's no way my OSM skills are l337 enough to be able to draw a way precisely 71ft 6in long. cheers Richard _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
