I heard of people looking at the position of stars (on night photos) and the sun to guess the latitude.

There was a story during the 2016 US election campaign where someone had a webcam pointed at a flag for some of the parties, and some folks managed to find the location by observing the stars and drove there and changed the flag, or something like that.
