Please forgive my ignorance, I know very little about map projections.
I apologize if this list is not the appropriate place to post this question.
If I understand correctly, in the Mercator projection, 1 unit of space
is equal to 1 meter at the equator.
As you move away from the equator, the longitudinal lines are stretched
to make the lat and long intersect at 90 degree angles.
How would I calculate the length in meters of 1 unit of space in the
Mercator projection at a specific latitude?
Any advice of pointers are appreciated.
