- Abstract
- This report presents photometric measurements on shore lights of the New York harbor area, taken from three observation points. In particular, measurements were made of the illuminance at the observation point due to distant lights, considered to be point sources. This is a measure of point source intensity appropriate to this situation, and quantifies what a mariner will see sailing into or out of New York harbor at night. The measurements are of interest because lights on shore make it hard to see the lights maintained by the U.S. Coast Guard as aids to navigation. One conclusion is that most of the interfering lights are high-pressure sodium vapor lamps used to light the streets, roads, and docks. The distributions of the lights in intensity, position, and color are presented graphically.
