This project, overall, consists of a spring 2018 lidar survey collected over an Area of Interest (AOI) in south-central Louisiana covering a total of approximately 3,772 square miles and includes the parishes of Acadia, Jefferson Davis, Allen, Evangeline and portions of St. Landry, Lafayette, Vermillion, Rapides and Calcasieu. Lidar data and derivative products were collected and processed to conform to the USGS National Geospatial Program Lidar Base Specification, version 1.2 (2014) at National Enhanced Elevation Assessment (NEEA) Quality Level 1 (QL1) with an Aggregate Nominal Pulse Spacing (ANPS) of 0.35 meters or less and Aggregate Nominal Point Density (ANPD) of 8 points per square meter or greater. Deliverable lidar products include: classified lidar point cloud, hydro-flattening breaklines, bare-earth digital elevation models (DEMs), and lidar intensity images. This metadata record supports the data entry in the NOAA Digital Coast Data Access Viewer (DAV). For this data set, the DAV is leveraging the GeoTIFF files hosted by USGS on Amazon Web Services.
