Nothing is square....

This is one of the first rules you learn in remodeling. I poured over the maps yesterday and got a refresher course. Parts of the map overlap a bit, parts dont line up, some of the maps are not even square, having a concave edge to them. The graphics software is likely making errors when doubling the size of the maps, etc. Going to have to approach this from a slightly different angle. Here are 2 sections of the map at full size to give you an idea of the scale. The walls and towers will be 3d printed and the terrain is going to have the approximately proper elevations.
