Shoreline mapping is conducted to produce shoreline for NOAA's nautical charts. The first surveying method used was "Plane-Table Mapping". Using this method, the surveyors sighted on features to be mapped from several known locations. This enabled the features to be located at the point where the lines intersected. Beginning in 1919, the Survey began using aerial photographs to produce shoreline maps. Today additional remote sensing techniques such as: digital imagery, LIDAR, IFSAR, and Hyperspectral Imagery are used.
