Making this into a game was the first thing I thought. It could be as simple as having a game mode that puts a small country map in the corner; you click where you think the view is and receive a score based on how close you are. This could be surprisingly fun and addictive.
Yeah, I immediately checked the "hide location" box and tried to start guessing countries. Vegetation helps get it down to very wide bands, but I bet with some experience you could get it pretty specific.
