The requested lidar area of interest (AOI) totals approximately 160 square miles, or 102,243 acres. This area was buffered by 100 meters to ensure data coverage, resulting in a total area flown (TAF) of 105,074 acres. This data set contains point cloud data(' in LAZ (compressed LAS) format', '').

These are in orthometric NAVD88 vertical datum. download dataset Vertical Positional Accuracy absolute accuracy RMSE = 0.08 feet (0.024 meters) standard deviation = 0.13 feet (0.04 meters) Note: These are the values from the data report. RMSE less than standard deviation does not make mathematical sense! Relative accuracy from examining overlapping flightlines has a standard deviation of 0.29 feet (0.09 meters). Given these inconsistencies, the true absolute accuracy is unclear and it may be safer to use a value on the order of 0.10 meters. The LiDAR survey utilized a Leica ALS50 Phase II sensor mounted in a Cessna Caravan 208B. The Leica ALS50 Phase II system was set to acquire greater than 105,000 laser pulses per second (i.e. 105 kHz pulse rate) and flown at 900 meters above ground level (AGL), capturing a scan angle of ±14 degrees from nadir (see Table 2.1). These settings are developed to yield points with an average native pulse density of 8 points per square meter over terrestrial surfaces. Some types of surfaces (i.e., dense vegetation or water) may return fewer pulses than the laser originally emitted. Therefore, the delivered density can be less than the native density and vary according to distributions of terrain, land cover, and water bodies. The study area was surveyed with opposing flight line side-lap of at least 50% (100% overlap) to reduce laser shadowing and increase surface laser painting. The system allows up to four range measurements per pulse, and all discernable laser returns were processed for the output dataset. 2008-09-05T00:00:00 Point cloud data were classified for ground points by Watershed Sciences. Ground points were given a point class of two (2) as specified by the LAS 1.1 format. Unclassified points were given a class of one (1). Classified point clouds were received by NOAA from US Forest Service in Washington State Plane North NAD83(HARN), NAVD88/Geoid03. For ingest into the Digital Coast Data Access Viewer, the data were converted to geographic coordinates and the geoid model was removed. 2023-02-09T00:00:00 NOAA Office for Coastal Management (843) 740-1202 coastal.info@noaa.gov processor Classified point cloud USFS originator The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. 2026-06-24NOAA Office for Coastal Managementcoastal.info@noaa.govprocessor otherRestrictions otherRestrictions This data set was compiled dynamically.
