Agreed. There is no observation that will tell you whether a road is more important than another road that is not where you are. But you can identify physical characteristics.

Therefore, I'm advocating objectivity vs subjectivity. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
