From lostpedia (http://lostpedia.wikia.com/wiki/The_Numbers):
Latitude 4.815, Longitude 162.342 are the GPS coordinates that lead to a point in the Pacific Ocean on the trail from Australia to L.A. (see Mapquest: [3] or Google Earth: [4] or Google Maps [5] [the former requires Google Earth being installed])
Looking on Google Maps, 151.6 miles due east of latitude 4.815n, longitude 162.342w, you will find a small island with no discernible features of note (it is called "Manounou", and its coordinates are 4.8n, 160.4w; 4+8+1+6+4=23). Continue 108 miles due southeast of that island, and you will find Tabuaeran, also called "Fanning Island" [6] which can be found at 4n, 160w -- take a look on Google's satellite photos [7] for yourself if you don't believe it.
