This project will support the 3DEP mission, the Natural Resources Conservation Service (NRCS) high resolution elevation enterprise program, and the Federal Emergency Management Agency (FEMA) Risk Mapping, Assessment and Planning (MAP) program, as well as many South Carolina state and local agencies. ![]() These checkpoints were not used to calibrate or post process the data.Ģ020 USGS Lidar DEM: Savannah Pee Dee, SC ![]() Additional independent accuracy checkpoints were collected and used to assess the vertical accuracy of the data. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, Woolpert established ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. Ground Conditions: Lidar was collected January through March 2020 while no snow was on the ground and rivers were at or below normal levels. Lidar data was delivered as processed LAS 1.4 files formatted to individual 5,000-Int'l. The data was developed based on a horizontal datum/projection of NAD83 (2011) State Plane South Carolina (FIPS 3900) International Feet (EPSG 6570), and a vertical datum of NAVD88 (GEOID18) US Survey Feet. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.3. Project specifications were based on the U.S. Geographic Extent: Approximately 21,453 square miles across South Carolina īlock 1 (Lot 6 QL2) - approximately 3,583 square miles in Anderson, Cherokee, Greenville, Laurens, Newberry, Oconee, Pickens, Spartanburg, and Union countiesīlock 2 (Lot 7 QL1) - approximately 950 square miles in Greenville and Lexington countiesīlock 3 (Lot 7 QL2) - approximately 3435 square miles in Abbeville, Aiken, Anderson, Edgefield, Greenwood, Laurens, McCormick, Newberry, Oconee, and Saluda countiesīlock 4 (Lot 8 QL1) - approximately 135 square miles in Aiken and Edgefield countiesīlock 5 (Lot 8 QL2) - approximately 5,775 square miles in Aiken, Allendale, Bamberg, Barnwell, Calhoun, Chester, Chesterfield, Clarendon, Colleton, Edgefield, Fairfield, Hampton, Kershaw, Lancaster, Lee, Lexington, McCormick, Newberry, Orangeburg, Richland, Saluda, and Sumter countiesīlock 6 (Lot 9 QL2) - approximately 7,255 square miles in Bamberg, Beaufort, Berkeley, Charleston, Chesterfield, Clarendon, Colleton, Darlington, Dillon, Dorchester, Florence, Georgetown, Hampton, Horry, Jasper, Kershaw, Lee, Marion, Marlboro, Orangeburg, Sumter, and Williamsburg countiesīlock 7 (Lot 9 QL1) - approximately 689 square miles in Beaufort, Berkeley, Charleston, Colleton, Darlington, Dorchester, Florence countiesĭataset Description: The SC Savannah Pee Dee 2019 B19 lidar project called for the planning, acquisition, processing, and production of derivative products of QL 1 and QL2 lidar data to be collected at a nominal pulse spacing (NPS) of 0.35 and 0.71 meters. Product: Lidar based digital elevation model (DEM) data tiles for ground classified points. OCM Partners, 2024: 2020 USGS Lidar DEM: Savannah Pee Dee, SC.
