These improve on the work of :cite:`Vincenty1975` in the following respects: * The results are accurate to round-off for terrestrial ellipsoids (the - error in the distance is less then 15 nanometers, compared to 0.1 mm + error in the distance is less than 15 nanometers, compared to 0.1 mm for Vincenty). * The solution of the inverse problem is always found. (Vincenty's method fails to converge for nearly antipodal points.) |
