- Here's a geometry question that I have:
-
- Say I have two points on the surface of the Earth which are
- sufficiently close enough to regard the line connecting
- them as being straight and not an arc. I need to find the
- angle between the line connecting the two positions and the
- arc connecting the southernmost point to the north pole.
-
- N.Pole
- pt 1 |
- * |
- \ | <-- An arc
- \--|
- \ | <-- The angle
- \|
- *pt 2
-
- I need a formula for the angle given the points' latitude and
- longitude.
