National Shoreline

NOAA National Geodetic Survey

Overview

The National Shoreline provides critical baseline data for updating nautical charts, managing our coastal resources, and defining our nation’s territorial limits, including the Exclusive Economic Zone. It is delineated through various photogrammetric sources, including tide-coordinated stereo aerial photographs, commercial satellite imagery, lidar, and other related remote sensing technologies.
