These data were collected by Quantum Spatial, Inc. (QSI) for the National Oceanic and Atmospheric Administration (NOAA), National Geodetic Survey (NGS), Remote Sensing Devision (RSD), Coastal Mapping Program (CMP) using a Riegl VQ880G system. The dataset includes topobathy data in a LAS 1.2 format file with the following classification: unclassified (1), ground (2), noise (7), overlap default (19), overlap ground (20), overlap water column (21), overlap water surface (22), water column (25), bathymetric bottom or submerged topography (26), water surface (27), and temporal bathy bottom (31), in accordance with project specifications. The contracted project consisted of approximately 519,590 acres along the Atlantic Coast of South Carolina. To ensure complete coverage and adequate point densities around survey area boundaries, the Area of Interest (AOI) was buffered by 100m. LAS files were compiled by 500 m x 500 m tiles. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
