Hi all,

I need to calculate the distance between two projected points - NOT the "real-world" planar/geodesic/great-elliptic distance - BUT the distance as it would appear on a paper map (in millimeters) for a given projection and map scale.

How could I do that? Any help would be really appreciated

Pythagorean theorem ? perhaps the two points you have would be useful, since there must be more to the question than meets the eye if you have ruled out planar and geodesic shapes from the start
