Emple calculates a set of GPS coordinates on his chalkboard, then he uses a GPS unit to travel to the location. When he's getting closer to his destination, his GPS unit gives his current location as 40.678633599 -74.018054655 and his destination as 40.678637003 -74.01853001, placing him inside a warehouse and causing him to move through it. In real life, those coordinates are, respectively, a spot in Louis Valentino, Jr. Park and a spot in the water just off shore of the park.
