USACE, NAVO, NOAA and USGS partner to collect high-resolution, high-accuracy topographic and bathymetric lidar and imagery data through the Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX). The partners acquire these data operationally with in-house survey capabilities and those of commercial survey providers under contract. Research and development in airborne lidar bathymetry and complementary technologies occurs through partnerships with industry and academia. USACE acquires these data under a National Coastal Mapping Program (NCMP). Headquarters initiated the NCMP in 2004 to provide these data along sandy shorelines of the U.S. on a recurring basis. Currently in the third update cycle, the NCMP provides scientists and engineers a suite of standardized, interoperable GIS data products that include lidar point clouds, digital surface and terrain models, elevation contours, and imagery mosaics. Product coverage extends from 500m inland to 1km offshore. Products are integrated with other topographic and hydrographic datasets, and provide critical updates to elevations in dynamic coastal areas. We share a 2018 example from the Gulf of Mexico in ArcGIS Pro.
