Yes, but you'll know the name of the city/state/country and its approximate distance from where you're currently standing, not it's [i]exact pin-point[/i] position on the globe. I have a rough estimate of how far Chicago, IL is from Houston, TX, but I won't know the exact distance mileage nor will I know the highways and roads to take if I want to go there unless I made use of a GPS system, the internet or if I asked for directions on the way.

Darkwolf is trying to get the exact (see: mathematical) orbits and positions of planetary bodies (things that an astronomer/cartographer would know) out of a random street urchin. You'd be better off breaking into a computer for that knowledge.
