This feature class provides a suite of coastal geomorphology features developed by the Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) using datasets provided from the USACE National Coastal Mapping Program (NCMP) and other Federal mapping partners. The JALBTCX mission is to perform operations, research and development in airborne lidar bathymetry and complementary technologies to support the coastal mapping and charting requirements of the US Army Corps of Engineers, the US Naval Meteorology and Oceanography Command and the National Oceanic and Atmospheric Administration. The USACE NCMP acquires high-resolution, high-accuracy topographic/bathymetric lidar elevation and imagery on a recurring basis along the sandy shorelines of the US. The program's survey footprint includes an approximately 1-mile wide swath of topography, bathymetry and imagery 500-m onshore and 1000-m offshore. The standard suite of NCMP data products include topographic/bathymetric lidar point clouds, digital surface and elevation models, shoreline vectors and both true-color and hyperspectral imagery mosaics. Value-added derivative information products may include laser reflectance images, landcover classification images, beach volume change and coastal geomorphology metrics and the Coastal Engineering Resilience Index (CERI). The CERI is designed to quantify the resiliency of beach and dune systems in coastal areas with the assumption that higher dunes and wider berms provide more resilience. The CRI considers beach and dune morphologic metrics as well as disturbance factors such as local storm surge and wave height. The combination of these variables leads to five non-dimensional factors: Protective Elevation (PE), Volume Density (VD), Protective Width (PW), Crest Freeboard (CF), and wave run-up (WR). The CRI is the summation of these five factors. The CRI is applied at a regional scale and successfully identifies locations of anticipated high and low resiliency.
