Mapping style for aliens?
I've recently come up with the idea of mapping an alien world (no humans). It seemed like an interesting idea to try and map something from an 'alien perspective'. This would mean something different than we are all used to (unless they develop their cartography along convergent lines). But, what could this 'different' be? That's what I'm here asking for help with. Ideas for an alien mapping style. I wasn't really wanting to go so far as to change the spectrum of light the aliens use (resulting in a map of wierd colour combos).
