Chart Updating
In 1962, the National Ocean Service, the Coast Guard and the Auxiliary entered into an agreement for mutual cooperation. National Ocean Service (NOS) agreed to furnish each participating Auxiliary Flotilla with a set of charts of its local area. In return, the Auxiliary agreed to report data useful for chart corrections to National Ocean Service, Marine Chart Branch. The personal knowledge of those in the Auxiliary resulted from frequent operation in their areas and is vital to the chart certification activities of U.S. Coast & Geodetic Survey, and the Marine Chart Branch. The purpose of this cooperation program is to properly report all current chart revision information, in the interest of safe navigation, for mariners.
