Lidar-derived Beach Morphology (Dune Crest, Dune Toe, and Shoreline) for U.S. Sandy Coastlines

October 27, 2020

The U.S. Geological Survey (USGS) National Assessment of Coastal Change Hazards (NACCH) project aims to identify areas of the nation's coastline that are most vulnerable to extreme storms and long-term shoreline change. These assessments require coastal elevation data across diverse geographic regions and covering a time span of many years. The datasets published here, organized by individual field activity numbers (FANs), define the dune crest (denoted by DC in the feature_type attribute), dune toe (denoted by DT in the feature_type attribute), and shoreline (denoted by SL in the feature_type attribute) at 10 meters (m) intervals alongshore for each processed lidar elevation survey. Beach width and beach slope as calculated from dune toe to shoreline are also included at each shoreline location.
