In my native Danish, up and down are used fairly much as described in the article, but genrerally only for smaller, provincial locations. From Copenhagen I can go down to the southern part where I live, but from here I can not go up to Copenhagen. East- and westwise, I can go over [exact same word] to some neighboring locations, though by no means all. As a native speaker I know when and when not, but don't have a clue as to any formal rule. No out. The west was never a wilderness to be conquered here.
