Summary

The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from both older sources, such as aerial photos or topographic surveys, as well as contemporary sources like lidar point clouds and digital elevation models (DEMs). These shorelines are compiled and analyzed in the Digital Shoreline Analysis System (DSAS) software to compute rates of change. It is useful to keep a record of historical shoreline positions as a method of monitoring change over time to identify areas most susceptible to erosion or accretion. These data can help coastal managers understand which areas of the coast are vulnerable to change. This data release and other associated products represent an expansion of the USGS national-scale [...]

Purpose

The shoreline data in this data release were digitized from georeferenced photographs, using the high-water line, ground water exit point, wet-dry line and instantaneous water line as specified in the shoreline type description of the data and attribute section of the metadata. This data release also provides a detailed classification of the coast from aerial photo interpretations. These data are used in conjunction with other compiled shorelines provided in complementary data releases to calculate rates of shoreline change.
