Product: These lidar data are processed Classified LAS 1.4 files, formatted to 4802 individual 1500 m x 1500 m tiles; used to create intensity images, 3D breaklines and hydro-flattened DEMs as necessary. Geographic Extent: Upper Delta Plain, Louisiana, covering approximately 3843 square miles. Dataset Description: This Upper Delta Plain QL2 Lidar project called for the planning, acquisition, processing, and derivative products of lidar data to be collected at an aggregate nominal pulse spacing (ANPS) of 0.7 meters (2ppsm). Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.2. The data was developed based on a horizontal projection/datum of NAD83 (2011), Universal Transverse Mercator (zone 15 N), meters and vertical datum of NAVD88 (GEOID12B), meters. Lidar data was delivered as flightline-extent unclassified LAS swaths, as processed Classified LAS 1.4 files, formatted to 4802 individual 1500 m x 1500 m tiles, as tiled Intensity Imagery, as tiled bare earth DEMs, and as tiled digital surface models; all tiled to the same 1500 m x 1500 m schema. Ground Conditions: Lidar was collected in early 2017, while no snow was on the ground and rivers were at or below normal levels. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, Terrasurv, Inc. established a total of 63 ground control points that were used to calibrate the lidar to known ground locations established throughout the Upper Delta Plain, Louisiana project area. An additional 179 independent accuracy checkpoints, 101 Bare Ground/Low Grass landcovers (101 NVA points), 67 in Tall Weeds/Brush categories, and 11 in Woods category (78 VVA points), were used to assess the vertical accuracy of the data. These checkpoints were not used to calibrate or post process the data. The NOAA Office for Coastal Management (OCM) downloaded 4802 LA_UpperDeltaPlain_2017 laz files from this USGS site: ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/Elevation/LPC/Projects/USGS_LPC_LA_UpperDeltaPlain_2017_LAS_2018/ and processed the data to the Data Access Viewer (DAV) and https. One file was determined to be empty and verified by USGS. Number of laz files processed was 4801. Noted some Class 3 (low vegetation) points in water body areas. In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record. Hydro breaklines are also available.
