Description:"Technical Memorandum CS-32 assessed the use of existing U.S. Army Corps of Engineers' (USACE's) National Coastal Mapping Program (NCMP) Airborne Lidar Bathymetry (ALB) data for hydrographic purposes. The conclusions of the study were positive about the potential use of USACE ALB data to fill in data gaps in coastal bathymetry (nearshore areas that are low priority for hydrographic surveys). This Technical Memorandum outlines USACE's current ALB processing workflow, provides a recommended workflow for data obtained from USACE by Coast Survey for use in NOAA products and offers a first step in estimating an ALB survey uncertainty value. In addition, the uncertainty components for the workflow procedure are identified and evaluated (separately and as a final product). A first-order approximation of the horizontal and vertical uncertainty components for the ALB survey data set as a whole were calculated. The two main values used to calculate the survey uncertainty are the empirical uncertainty values, calculated from calibration sites that are used at the beginning of every survey season, and VDATUM uncertainty maps"--Executive Summary [doi.org/10.7289/V5/TM-NOS-CS-36 (https://doi.org/10.7289/V5/TM-NOS-CS-36)]
