You used a globe which could be considered a
artistic rendition of what the Earth looks like, but isn't necessarily
a true rendition of what the complete picture is because it's heavy on
continental distribution.
You lost me on that one. As long as the globe accurately represents
the latitude and longitude of significant surface points (and most do
in my experience unless they are antique), then you should be able to
determine viable great circle routes with a reasonable degree of
accuracy.

As I understand it, and I'm not a cartographer, globes are not
accurate representations of the Earth - unless, of course, you have a
really expensive one that accounts for the slight egg shape - most are
completely and exactly round and the Earth isn't. Plus, as I
understand it, globes are "artistic in the sense that they emphasize
land mass over ocean mass.

Hence the term distribution and the different types of projections
that can be used. Again, as I understand it, you can concentrate on
one or the other or even move the model point to emphasize one thing
or another or even have a moving point in representing land or ocean
masses and stuff like that.

I don't know - it was just a thought.
