Distorsion is one thing, it makes Sweden (and Finland) to look visually ridiculous on the map, but it does not mean that these countries are twice as large in the real life. Scale bar values, if presented in meters/feet, should be adjusted according to latitude. Even then it cannot be correct for the whole map, but showing the corrrect scale for the middle latitude of a would perhaps be the best compromise. Of course if scale were presented in degrees then it would be correct universally, but that would not be very useful for average users. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
