|void calc_gc_course_dist||(||const Point3D &||start,|
|const Point3D &||dest,|
Calculate new lon/lat given starting lon/lat, and offset radial, and distance.
NOTE: starting point is specifed in radians, distance is specified in meters (and converted internally to radians) ... assumes a spherical world.
|orig||specified in polar coordinates|
