The Cooperative Charting Program of the United States Power Squadrons is conducted in close coordination with the Marine Chart Division, National Ocean Service, National Oceanic and Atmospheric Administration of the U.S. Department of Commerce.  The Program is a major public service of USPS.  Under it, members supply information to the Marine Chart Division of NOS/NOAA leading to corrections to nautical charts, small craft charts, and Coast Pilot publications.  They also supply data on depth surveys, range status, geodetic marks, and formerly, aeronautical charts.  The Adopt-A-Chart subprogram enables individual squadrons to adopt a chart in their location and get recognition on new editions for their work. We have been told that the Cooperative Charting Program is recognized as the most effective user-participation program in all of the Federal services.
