I have an object (A) at some altitude above the Earth ellipsoid, and a point (B) on the surface of the Earth.
Since you're not confined to the surface of the Earth as you travel from A (at altitude), to B, I'm getting confused.
If I were to create a (Cartesian) vector pointing from object A in the air, to point B on the ground,
would a rhumb line, or a great circle be a more accurate representation of the vector if I were to put the discretized values of the vector in terms LLA (latitude, longitude, and altitude)?
Maybe a better way to ask is: What is the LLA projection of the Cartesian vector pointing from A to B? And would that projection be better represented as a rhumb line, a great circle, or some other calculation?
Thanks
