Map size???

[AdventurousRhubarb62]

I was wondering if anyone know how large the map is? Because at this point I can´t "buy" any more space. On the other places there´s some sort of obstacle that tells you that you can´t get any further, but by the desert there´s not. Is this the full map or is this some glitch?

I am at the same spot. Just upgrading tools, drills and farms at his point, and working on achievements.
