Without rounding and assuming negative values vor lat/lon in case of south/west coordinates and start and end being zoomlevels that are included in the count I think (didn't test it ;)) this should be correct: tilesX = 2^(start-1)*($w-$e)/360 tilesY = 2^(start-1)*($n-$s)/180 tilesX*tilesY * 4^(end-start) Regards, Peda p.s. you should start a new topic for new questions. However, you replied to another topic and just changed the subject. -- _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
