Find shortest path between two points, find curve that crosses meridians at same angle

A great circle is the shortest path between two points along the surface of a sphere, a geodesic is the shortest path between two points on a curved surface, and a rhumb line is a curve that crosses each meridian at the same angle. Use these functions to:

  • Find distances and azimuths along great circle, geodesic, and rhumb line tracks.

  • Find the coordinates of reckon points and antipodes.

  • Find the coordinates of track points along great circle, geodesic, and rhumb line tracks.

  • Find the intersection points of great circles, geodesics, and rhumb lines.
