No known data gaps exist (with the exception of water areas) within the project area. Conceptual Consistency Elevation and hydrography data was delivered covering the full extent of Jasper and Colleton Counties, and partial county coverage of Charleston County. JASPER COUNTY: Utilizing Photo Science's two ALS-50 LiDAR sensors, data was collected to cover Jasper County, South Carolina. Data was collected in a total of 111 flightlines at a pulse rate of 75,000 points per second. COLLETON COUNTY: Utilizing Photo Science's two ALS-50 LiDAR sensors, data was collected to cover Colleton County, South Carolina. Data was collected in a total of 160 flightlines at a pulse rate of 75,000 points per second. CHARLESTON COUNTY: Utilizing Photo Science's two ALS-50 LiDAR sensors, data was collected to cover Charleston County, South Carolina. Data was collected in a total of 77 flightlines at a pulse rate of 75,000 points per second. 2007-03-23T00:00:00 Raw LiDAR data (collected as Process Step 1) was processed to create a bare ground surface. Process included calibration of LiDAR data to remove systematic errors (utilizing Leica's ALS Processor software), adjustment of elevation data to control positions (utilizing TerraScan software for control comparisons and adjustments), and both automatic and manual editing to correctly classify ground and non-ground data (utilizing TerraScan and TerraModeler software). In addition, QC steps were performed before and after processing. QC steps included line-to-line vertical comparisons and coverage checks, and were performed with TerraScan and GeoCue software. 2007-10-30T00:00:00 Following bare ground surface creation (Process Step 2),Photo Science utilized the resulting dataset as a source for collection of hydrographic features, including double-line drains, single-line drains, and bodies of water. Hydro features were collected from bare ground surface models in MicroStation v8 software. After collection was complete, Photo Science adjusted elevation of all hydro features to ensure proper monotonicity using FME and proprietary software. 2007-10-30T00:00:00 The NOAA Office for Coastal Management (OCM) received files in LAS format. The files contained LiDAR intensity and elevation measurements. OCM performed the following processing on the data to make it available within the LiDAR Data Retrieval Tool (LDART) 1. The data were converted from UTM (Zone 17) coordinates to geographic coordinates. 2. The LAS data were sorted by latitude and the headers were updated. 2008-03-21T00:00:00 Source Contribution: Raw LiDAR elevation data utilized in production of final bare ground surface. | Type of Source Media: Hard Drive Jasper, Colleton and Charleston Counties, South Carolina 2007-10-30 publication 2006-12-27 2007-03-23
