Tobias,

Thank you for that suggestion. I am now using the geographiclib routines in
Shape Tools' XY to Line routine that was released today. I am still
including Great Circle as an option and if you zoom in you can see the
differences.

All the best,

Calvin

Wait, it's way better to use this one:
> https://geographiclib.sourceforge.io/
>
> There's a Python port and it's extreme accurate and quick.
> It's under MIT and it works great (just tested it).
>
> It also works with WGS84 and all other ellipsoids (WGS84 should be
> fine for most of the users).
>
> This might be the easiest and best way for accurate distances and
> azimuths.
