Milky Way Galaxy
Nobody has ever done something on this scale, although I'm not sure that means it should be done. This galaxy is an odd shape and trying to recreate it as a map will, in my eyes, almost definitely turn out to not contain any strategy in the slightest.

Old World (Europe, Asia, Africa)
We already have a lot of historical maps, however you haven't specified what era you are referring to.
Again, refer to the first set of links, although this could be quite interesting.
