98LTS05	Airborne Topographic Mapper 2 (ATM2) The Airborne Topographic Mapper 2 (ATM2) is part of NASA’s Airborne Topographic Mapper system, a series of scanning lidar instruments designed to measure Earth’s surface topography with high precision. ATM2 is one of the second-generation instruments in the ATM series, which was operational from the mid-1970s to 2022.
07CNT01	Light Detection and Ranging (Lidar) Lidar is an active remote sensing technology that uses laser pulses to measure distances to objects or surfaces. By calculating the time it takes for each laser pulse to travel to a target and return, lidar systems generate highly accurate 3D point clouds representing terrain, vegetation, and built structures. Vertical accuracy often within 10–15 cm.
10CNT08	Light Detection and Ranging (Lidar) Lidar is an active remote sensing technology that uses laser pulses to measure distances to objects or surfaces. By calculating the time it takes for each laser pulse to travel to a target and return, lidar systems generate highly accurate 3D point clouds representing terrain, vegetation, and built structures. Vertical accuracy often within 10–15 cm.
