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. Landry, Lafayette, Vermillion, Rapides and Calcasieu. 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. The classified point cloud was produced to meet the specifications detailed in the USGS National Geospatial Program Lidar Base Specification, version 1.2 (2014).
