The Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) mission is to perform operations, research, and development in airborne lidar bathymetry and complementary technologies to support the coastal mapping and charting requirements of the US Army Corps of Engineers (USACE), the US Naval Meteorology and Oceanography Command, and the National Oceanic and Atmospheric Administration (NOAA). JALBTCX staff includes engineers, scientists, hydrographers, and technicians from the USACE Mobile District, the Naval Oceanographic Office (NAVOCEANO), the USACE Engineer Research and Development Center (ERDC), and NOAA National Geodetic Survey. <p style='margin-top: 0px; margin-bottom: 0px; font-family: "Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", Helvetica, Arial, sans-serif; background-color: rgb(255, 255, 255); box-sizing: border-box;'>JALBTCX executes survey operations worldwide using state-of-the-art topo/bathy lidar systems and other industry-based coastal mapping and charting systems. JALBTCX's latest in-house survey capability includes a Teledyne Optech CZMIL lidar instrument with simultaneous topographic and bathymetric capabilities. CZMIL is integrated with an Itres CASI-1500 hyperspectral imager and a 150 MP PhaseOne RGB camera. CZMIL collects 10-kHz lidar data with spatially- and temporally-concurrent digital true-color and hyperspectral imagery. Survey operations support the USACE National Coastal Mapping Program and NAVOCEANO nautical charting missions. Survey operations support the USACE National Coastal Mapping Program and NAVOCEANO nautical charting missions. The USACE National Coastal Mapping Program (NCMP) acquires high-resolution topographic/bathymetric lidar elevation and imagery on a recurring basis along the sandy shorelines of the US. The typical survey footprint includes an approximately 1-mile wide swath of topography, bathymetry, and imagery 500-m onshore and 1000-m offshore. The standard suite of NCMP data products include:<ul><li>topographic/bathymetric lidar point clouds</li><li>digital surface models</li><li>digital elevation models</li><li>NAVD88 0-meter shoreline vectors</li><li>true-color and hyperspectral imagery mosaics</li></ul>Value-added derivative information products may include:<ul><li>laser reflectance images</li><li>landcover classification images</li><li>volume change metrics </li></ul><div style='font-family: "Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", Helvetica, Arial, sans-serif; background-color: rgb(255, 255, 255);'>USACE Headquarters initiated the NCMP in 2004. The program's update cycle follows counter-clockwise along the US West Coast, Gulf Coast, East Coast and Great Lakes approximately every 5 years. Surveys in support of USACE project-specific missions and external partners are included constituent to the current NCMP schedule and reimbursable funding. All work is coordinated with Federal mapping partners through the Interagency Working Group on Ocean and Coastal Mapping and the 3D Elevation Program. </div>
