Theran maps are basically a "general" layout of the world/city.

If you look at the maps of Thera (east and west) for example, they just point out the general directions to everything. Some smaller maps of cities and forest can be a lot more precise but for the most part, you got to remember they are hand drawn and can be slightly off sometimes.

I blame the cartographers coffee adiction, but that's just me.
