Yep, your post made me realise that I was a little stupid to ask for a map with a mountain range and a bunch of cities carved into the northern side of said mountain range.

Obviously I know nothing about making maps on a computer, so I'm afraid I can't give you any advice on that, but I can say that it wouldn't bother me the least bit if you turned the map upside-down (actually, I guess it would make much more sense for a map made in a southern continent to have south on top and north at the bottom, since top is usually associated with higher hierarchy and so on...).

Still, any decision you make to fix this problem, be it putting south on top or using a satellite perspective, I'll be happy with.
