Jose, this project is very cool. I would be interested to see if you could use GeoProjection->"Orthographic" to display the old map in the Orthographic projection, which would show what it would look like on a sphere! Which I think would be pretty amusing as well as insightful to its accuracy.
thanks for showcasing the GeoGraphics capabilities. I'm still playing around with it. Just got to know the GeoVariant function. Thanks!
