"Satellite map", that's quite a curious name for a skill in an RPG-styled world.
I suppose I could see people trying to rationalize such a name as being a reference to what the world might look like from the moon (a natural satellite, the only kind of satellite they'd have any concept of). Even then, I'm sure they'd find the choice of wording strange nonetheless, compared to something like "bird's eye".
But hey, who knows, maybe some madman somewhere's magicked their way into putting some magical artifact capable of photography and computation into stable orbit above their world. Or come up with the concept at the very least, even if unfeasible just yet.
