Chart Updating

CUWeb Cooperative Charting Reports
Cooperative Charting Members,

NOAA regrets that they had to suspend the CUWeb reporting site due to internet security concerns. While they will work with the U.S. Coast Guard Auxiliary on future reporting procedures, please submit nautical chart discrepancies and updates at Nautical Discrepancy Report System.

Thank you for your commitment to safe navigation. Please contact Ed Martin at with questions. 

 NOAA receives chart update information from the U.S. Coast Guard Auxiliary. The Cooperative Charting Program enables those members to report chart discrepancies by Internet throughout the country. If a chart discrepancy report is judged by NOAA cartographers to be “critical,” it is applied to the chart and furnished to the U.S. Coast Guard and NGA for inclusion in LNM and NMs.

New reporting site:

                        NOAA's Nautical Discrepancy Report System


Thank you for your assistance,
