Introduction to LidarLidar SystemsSystem SpecificationsApplications of LidarSee AlsoLIDAR is similar to radar technology, which uses radio waves, a form of electromagnetic radiation that is not in the visible spectrum. The range to an object is determined by measuring the time delay between transmission of a pulse and detection of the reflected signal. LIDAR technology has applications in Archaeology, Geography, Geology, Geomorphology, Seismology, remote sensing and many more areas. Light detection and ranging (LIDAR), also known as airborne laser scanning (ALS), is an emerging remFlorida-Based Land Surveyors Achieve QL0 LiDAR Scan for Oct 02, 2020 · Then, as the county planned on using the LiDAR for multiple purposes, including watershed Hydrological and Hydraulic modeling and planimetric mapping, the county cooperators required USGS LiDAR Base Specification (LBS) Quality Level 0, the most rigorous accuracy specification in the LBS.
