From the Ferris collection, of course.

This map is a pretty big file, and it can be printed at a variety of sizes if you have the technical know-how (don't ask me). It is about 7200 x 6800 pixels. It should print up fine at 26" to 36" square-ish, but someone has told me that it could be printed at up to 90" square with good resolution if you know what you're doing. I don't; I'm a 3D printing man myself.
Scale-wise, if printed so that it is 28" wide, 1" will equal 330m, or about 1" = 1 brigade.
Here's the entire map area:
The picture above is not the actual image file because my blog limits the file size of the images I upload.
Here's a zoom-in on the actual map, where 1" = 330m.
I'm hoping to one day create a set of rules that use the Ferraris maps, because they really have just about everything you could want from a war-gamers point of view. I just wish I could remove those hideous elevation lines (I'm sure there are programs that can do it, just not at my skill-set). One day!
Anyways, enjoy!
