I've been trying to model the map in 3D, and unfortunately while every angle of the first map(/hero prop) is shown in the movie, the surface symbols cannot be made out on around 20% of the maps surface.
Here's a screenshot of what I've been able to map it out so far, and a work in progress 3D render:

The parts highlighted in blue are the parts that I've been unable to get a good enough look at in the movie to accurately map out as of yet.
So I too would love to get a good look at the original map files.
But from what I can gather there's a distinct band of densely packed symbols around the equator of the map, and the symbols become larger and more spread out the further from there they are.
