NASA's Land, Vegetation, and Ice Sensor or "LVIS", is an airborne, wide-swath imaging laser altimeter system that is flown over target areas to collect data on surface topography and 3-d structure.

2024年2月16日 · NASA’s Land, Vegetation and Ice Sensor (LVIS) is a wide-swath, high-altitude, full-waveform airborne laser altimeter and camera sensor suite designed to provide elevation and surface structure measurements over hundreds of thousands of square kilometers.

The LVIS lidars are full-waveform laser altimeters, meaning that the systems digitally record both the outgoing and reflected laser pulse shapes providing a true 3-dimensional record of the surface and centimeter-level range precision.

Two LVIS lidars and one camera were operated on the NASA LaRC Gulfstream-III aircraft. Science targets included sections of GEDI reference ground tracks, areas where complementary ground and airborne-based data collections exist and LVIS data collection sites flown previously as part of the 2016 AfriSAR campaign.

2022年7月11日 · NASA's Land, Vegetation, and Ice Sensor or "LVIS", is an airborne, wide-swath imaging laser altimeter system that is flown over target areas to collect data on surface topography and 3-D structure.

NASA's LVIS is an airborne, medium-footprint (25m diameter), full waveform-recording, airborne, scanning lidar system that has been used extensively for mapping surface structure for various scientific investigations.

The Laser Vegetation Imaging Sensor (LVIS) is an airborne laser altimeter designed to quickly and extensively map surface topography as well as the relative heights of other reflecting surfaces within the laser footprint.

2 天之前 · NASA's Land, Vegetation, and Ice Sensor or "LVIS", is an airborne, wide-swath imaging laser altimeter system that is flown over target areas to collect data on surface topography and 3-d structure.

LVIS uses lidar scanning laser altimeters to collect topography and vegetation coverage data over land, ocean, and ice surfaces, along with downward-looking, high-resolution camera imagery. Collection periods for LVIS data products at the NSIDC DAAC range from 2007 to present.
