This product provides the most up-to-date shoreline of the United States and its territories. Shoreline is delineated and attributed through the combination of current shoreline surveys and emerging technology. This mean high-water proxy shoreline is based on vertical modeling or image interpretation using water-level stations or shoreline indicators. It has less stringent data acquisition requirements and quality control measures than other methods and does not include many alongshore features, such as piers.
