Survey Overview and Acquisition

Lidar beach morphology data were collected using the Coastal Lidar and Radar Imaging System (CLARIS) vehicle traveling approximately 5 kilometers per hour (km/h) along two 30-km shore-parallel transits. The seaward side of the dune and the upper beach were surveyed during the first transit, and the area from near the shoreline and the lower beach were surveyed during the second transit. The survey was designed to provide an area of extensive overlap used to verify system accuracy and assess survey precision.
