You get some point when you contribute. So if you have 500 points you are a level 5 local guide and if you have 100,000 points then you are a level 10 local guide. I'm a level 7 local guide and I have 6500 points right now. The point system is like this 5 points per review, photo or edit. 15 point for adding a new place and 1 point per rating, answer or fact checked.
