   Relationship to Geodesic Lines
   Geodesic lines (the shortest path between two points on an ellipsoid) are fundamentally dependent on geodetic latitude for their computation. The calculation of the forward azimuth ($\alpha1$) from a starting point ($\phi1, \lambda1$) to an endpoint ($\phi2, \lambda_2$) involves complex integration over the ellipsoid surface, where the latitude variations dictate the curvature of the path. This curvature is also subtly influenc…
