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 | Earthdata
WEBLidar stands for Light Detection and Ranging. It is a remote sensing method that uses light in the form of a pulsed laser to measure ranges. Lidar is the optical analogue of radar.

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.

WEBSep 4, 2019 · Lidar data are critical for: Mapping young deposits and landforms, which are those most essential to understanding Earth resources. Underpinning geologic mapping that guides assessment and development of solid-Earth resources: base and precious metals, sand and gravel, coal, oil, and natural gas.
WEBIn fact, most lidar data are collected at night. Unlike radar, lidar cannot penetrate clouds, rain, or dense haze and must be flown during fair weather. Lidar instruments can rapidly measure the Earth’s surface, at sampling rates greater than 150 kilohertz (i.e., 150,000 pulses per second).
