Seems pretty simple to me, importance is going to be partially subjective, even if 2 airports have similar number of flights, some will have 747s & 380s and some won't. highway=* classifications seems at least partially subjective as well. I see the need for at least 4 or 5 airport types, major international airports, minor international airports, regional airports, tiny airports and airstrips. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
