Shoreline Update Notices (SUN)
-
NOAA National Shoreline Update Notice Disclaimer - Please read carefully This service provides access to NGS shoreline updates that have been made to contemporary national shoreline data accessible through the NOAA Shoreline Data Explorer (NSDE) website. Subsequent to providing the shoreline data in the NSDE, discrepancies may be discovered during the application of the data to the nautical chart, during a Hydrographic or Navigation Response Team field survey, or by other users of the data. Some of these items, in turn, may require corrective action such as removing, adding, reshaping, or attribute modification in order to resolve the discrepancy. Shoreline updates may include information on aids to navigation changes, hazards to navigation or other information considered essential for safe navigation. While information provided by this web site is intended to assist in the updating of shoreline data available on the NSDE, it must not be used as a substitute for the United States Coast Guard, National Imagery & Mapping Agency or Canadian Coast Guard Notice to Mariner publications.
