The United States Defense Mapping Agency Hydrographic/Topographic Center publishes a list of lights. The National Geospatial-Intelligence Agency ( NGA) is an agency of the United States Government with the primary mission of collection analysis and The book is usually referred to as the List of Lights, and should not be confused with the U.S. Coast Guard's Light List.
The List of Lights is published in seven volumes, as Publication numbers 110 through 116. Each volume contains lights and other aids to navigation that are maintained by or under the authority of other governments.
Each volume corresponds to a defined geographic region, and contains more complete information about the navigational aids than can be conveniently shown on nautical charts. New editions are published annually for every volume.
In addition to information on lighted aids to navigation and sound signals in foreign waters, the DMAHTC List of Lights provides information on storm signals, signal stations, racons, radiobeacons, and radio direction finder calibration stations located at or near lights. A Racon is a type of Radar Transponder commonly used to mark maritime navigational hazards A radio direction finder ( RDF) is a device for finding the direction to a Radio source Publication number 117, Radio Navigational Aids, is the primary source for details on radio navigational aids.
The List of Lights does not include information on lighted buoys inside harbors. It does include certain aeronautical lights situated near the coast; however, these lights are not designed for marine navigation and are subject to unreported changes.
Notices to mariners provided by other countries are the main source for correctional information source for the Lists of Lights, however other sources, such as ship reports, are also used. Summary of Corrections A close companion to the Notice to Mariners is the Summary of Corrections.
