Please check coregQCFlag for a measure of rectification accuracy. Digital Elevation model collected using a Riegl VZ-1000 or VZ-2000 terrestrial laser scanner mounted on the North lidar tower at the United States Armp Corps of Engineers' Coastal And Hydraulics Laboratory's Field Research Facility (USACE/CHL/FRF) in Duck, NC. The Riegl VZ-1000 is the primary data collection instrument, with the VZ-2000 deployed while the VZ-1000 is being serviced.
