The U.S. Army Corps of Engineers (USACE), Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX), is performing airborne coastal mapping surveys along the shorelines of the Hawaiian Islands now through June as part of the USACE National Coastal Mapping Program (NCMP).

The surveys will be conducted using a contracted aircraft equipped with a USACE-owned Coastal Zone Mapping and Imaging Lidar (CZMIL) system. Lidar, which is short for “light detection and ranging,” uses light in the form of lasers to measure distance.
