For the experts: I am looking for a formula, preferably as
Java(Script)-code, to calculate the course between two lon/lat pairs as
a value between 0 (north), through 180 (south) to 360 degrees (like in
the values from a GPS RMC sample). I can calculate Great Circle
distance, but somehow couldn't find course-calculations Googling.
(Background is moving directional icons on a map). Any help appreciated.
