Abstract
This is a C implementation of the geodesic algorithms from GeographicLib. This is a self-contained library (requiring only the standard C math library) which makes it easy to do geodesic computations for an ellipsoid of revolution in a C program. It is incorporated into PROJ and many people might prefer to use these routines via PROJ.
This an implementation in C of the geodesic algorithms described in
- C. F. F. Karney, Algorithms for geodesics, J. Geodesy 87, 43–55 (2013); addenda.
