The Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) partnership is comprised of the U.S. Army Corps of Engineers (USACE), the U.S. Naval Meteorology and Oceanography Command, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Geological Survey (USGS). Both the
USACE and NOAA have requirements to collect topo-bathy lidar of the U.S. coastline, but for different intended applications. The USACE resurvey the contiguous U.S. coast every\ five to seven\ years through their National Coastal Mapping Program: an excellent resource to assist NOAA in meeting their nautical charting requirements. This paper summarizes how NOAA and USACE are investigating the topo-bathy lidar datasets and plans to ingest them into the NOAA charting pipeline to routinely update nautical charts on a national scale. Ultimately, reducing the deficit of recent and reliable near-shore coastal bathymetry for the U.S. mariner.

National Oceanic and Atmospheric Administration (NOAA) hydrographic data is typically acquired using sonar systems, with a small percent acquired via airborne lidar bathymetry for near-shore areas. This study investigated an integrated approach for meeting NOAA\’s hydrographic survey requirements for near-shore areas of NOAA charts, using the existing topographic-bathymetric lidar data from USACE\’s National Coastal Mapping Program (NCMP). Because these existing NCMP bathymetric lidar datasets were not collected to NOAA hydrographic surveying standards, it is unclear if, and under what circumstances, they might aid in meeting certain hydrographic surveying requirements. The NCMP\’s bathymetric lidar data are evaluated through a comparison to NOAA\’s Office of Coast Survey hydrographic data derived from acoustic surveys. As a result, it is possible to assess if NCMP\’s bathymetry can be used to fill in the data gap shoreward of the navigable area limit line (0 to 4 meters) and if there is potential for applying NCMP\’s bathymetry lidar data to near-shore areas deeper than 10 meters. Based on the study results, recommendations will be provided to NOAA for the site conditions where this data will provide the most benefit. Additionally, this analysis may allow the development of future operating procedures and workflows using other topographic-bathymetric lidar datasets to help update near-shore areas of the NOAA charts.
