Re^2: Alternatives To Geo::Distance (hack)

It seems to rapidly screw up as you move north.

The distance from (0,0)-(10,10) should be the same as from (80,0)-(90,10) as shown by the Geo::Distance output. Or should it?

The distance should go down closer to the pole. (90,10) and (90,0) are the same point. If you start at the north pole and walk one mile to the south and then one mile to the west you are still one mile to the south of the north pole. At the equator you will get a hypotenuse.	[reply]
