(Oops, didn't reply to the list.) Yep, they do. That was my first thought, but there's no min/maxscale things defined for >z18. From what I gather, everything that renders at z18 doesn't set a minscale to 18, so tiles for z19 to z22 render the same stuff as z18 just "scaled" up (which is fine by me). I'm not sure why z23 is the magic number where it breaks. -- john p. kiffmeyer _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
