1997 Sacramento Inland Floodplain Lidar

Published by Office for Coastal Management | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 19, 2025 | Last Modified: 2000-01-01T00:00:00.000+00:00
This data set includes data collected in October 1997 over the Sacramento, CA, floodplain. Laser mapping uses a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation and topography. The laser emits laser beams at high frequency and is directed downward at the earth's surface through a port opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The aircraft travels over the beach at approximately 60 meters per second while surveying from the low water line to the landward base of the sand dunes.
