Lidar - Wikipedia
WEBLidar (/ ˈ l aɪ d ɑːr /, also LIDAR, LiDAR or LADAR, an acronym of "light detection and ranging" or "laser imaging, detection, and ranging") is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
What is Lidar data and where can I download it?
WEBLight Detection and Ranging ( lidar) is a technology used to create high-resolution models of ground elevation with a vertical accuracy of 10 centimeters (4 inches). Lidar equipment, which includes a laser scanner, a Global Positioning System (GPS), and an Inertial Navigation System (INS), is typically mounted on a small aircraft.

What is lidar? - NOAA's National Ocean Service
WEBLidar — Light Detection and Ranging — is a remote sensing method used to examine the surface of the Earth. Lidar data collected using NOAA survey aircraft reveals a top-down and side view of Loggerhead Key Lighthouse, Dry Tortugas, Florida. NOAA scientists use lidar-generated products to examine both natural and manmade environments.

WEBMar 19, 2024 · Lidar, technique for determining the distance to an object by transmitting a laser beam, usually from an airplane, at the object and measuring the time the light takes to return to the transmitter. The word lidar is derived from light detection and ranging.
Lidar | Earthdata
WEBLidar is the optical analogue of radar. Lidar differs from radar in its energy source, a laser in the optical part of the electromagnetic spectrum (near IR and green). Lidar is used to measure things such as: range and altitude atmospheric vertical profiles of aerosols and trace gas densities temperature cloud cover wind velocity shape and size ...
WEBLiDAR Detector Modalities Discrete • Records individual returns representing the peaks in the waveform curve. • A discrete system may record 1-5 returns from each laser pulse. A collection of discrete return LiDAR points is known as a LiDAR point cloud. Full Waveform • Records the distribution of returned light.
