Yep, you're right, Mercator is no help. BTW, I rendered tiles (for marble) in Lat/Lon aka Geographic, Plate Carre, equirectangular,cylindrical equidistant, unprojected etc. Still, there are too many re-sampling artifacts. I'll try smaller tile sizes .. > > Have a nice day, > -- > Martijn van Oosterhout <[EMAIL PROTECTED]> http://svana.org/kleptog/ Cheers Artem _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
