Hi,
Fundamental issue is that the world is 4D and geodetic computation is 2D.
You can get a result that's nice mathematically, but the idea of "carry out
the calculations in full on the ellipsoid and thus be able to forget about
the projected CRS, and leave them purely for aesthetic purposes"
Jose Carlos,Buena respuesta. Tienes toda la razón.
Un abrazo.

Hi,
I was not expecting that answer and less to hear about calculations on
the sphere when we are talking about geodesy!.
The comparison between the spheroidal (local sphere) and spherical
intersection has already been made in the article. We did it because
some software uses this approach.
This is very interesting, but from a practical point of view the problems
around doing intersections on the spheroid are not to do with the
difficulty of calculating spheroidal intersection points, but the
difficulty in programming things that are relatively simple in cartesian
(R2) space in
Hi list,
I want to share our last research about gemetric operations on the
spheroid [1]
Considering two segments defined by 2 points each one over the spheroid.
We want to get the intersection point defined by these two segments.
Several points to note:
1.- We could not find any software
