Crowdsourcing map data itself isn't a surprise; it's been the cornerstone of OpenStreetMap and is about to get a big boost through iOS 6. Crowdsourcing actual positions is still a relatively untapped resource, however, and Google thinks that it might just be the ticket to getting a device's location when GPS alone doesn't cut it. Much as your current phone uses triangulation between cell sites to help speed up a position lock, a technique in a new Google patent application uses the physical distances between nearby devices to get a complete picture, even if GPS is completely on the fritz.
