Cooperative Charting is a major public service performed by the members of Americas Boating Club. Our Cooperative Charting Programs have been called two of the most effective civilian user-participation programs in the Federal Government. Through our Geodetic and Nautical reporting programs we supply information to the National Geodetic Service (NGS), and the United States Coast Guard on land based Geodetic Marks and ATONs. Reports on specific Geodetic Marks help improve the National Spatial Reference System (NSRS) prepare for the NSRS modernization in 2022 and the reports on ATONs help to keep the public aware of current Nautical Discrepancies that are a hazard to navigation.
