Anons, just my two cents here, but this:

is an amazing read. If 111 is important then the multiples of 111 may be significant as well. These numbers seem to crop up all over the place: 111, 222, 333, 444, 555, 666, 777, 888, 1221. There are some other numbers I see that are not multiples of 111 that could perhaps be of some use: 33, 1111, 1010, 1212, 123, 234, 345, 456, 1234, 1248, 124, 248, 256. There are more along this same logic (repeating, palindromes, sequences).
Again I have no idea if this helps with your map or not but just thought I'd throw it out there. Sorry if it's just schizo nonsense.
