As far as we know the coordinates in the film are 34° 8' 22.77N, and 19' 18.1" W. Now I'm pretty sure Nolan would use the coordinates to refer to something in batman history. As I looked over different filming locations in batman history I came across the Bronson Canyon which is where they filmed the cave for the 1960s T.V. show. Those coordinates for the Canyon are 34° 7′ 22.33″ N, 118° 18′ 55.8″ W. Now if we subistute 38° 8′ 22.77″ N, for 34° 7′ 22.33″ N and 19' 18.1"W, for 18′ 55.8″ W. This puts us near the cave called "the west portal", and this location is where they filmed the entrance of the batcave for the 1960s T.V. show. Therefore I think Nolan is alluding to the T.V. show through the coordinates which most likely are 34° 8′ 22.77″ N, 118° 19′ 18.1″ W
