Hi, I've found another proyect for 3D modelling.

This is the Castle of Burgos (Spanish castle at the Spanish city of Burgos) as it was when the French (Napoleonic troops) had Spain invaded for 5 years.
During this time, the french mappers and topographers took their measures and eventually drew the map:

I'm going to cross-reference the roads shown there with the heightmap of today to make the model:
