That's not exactly the argument. You can reverse-engineer the produced map tiles. But one interpretation of the ODbL (which I find to be persuasive) is that any significant extract of data which you obtained from such reverse-engineering would be ODbL, to the extent that a) it's copyrightable; b) it's protected by database rights; or c) you agreed to the ODbL. _______________________________________________ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
