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.
Utilizing a system that includes a 1064 nm-wavelength laser and 3 detectors, the entire time history of the outgoing
and return pulses is digitized, allowing unambiguous determination of range and return pulse structure.
Combined with aircraft position and attitude knowledge, the sensor produces topographic maps with
decimeter accuracy and vertical height and structure measurements of overflown terrain, e.g., vegetation and ice.
LVIS operates at altitudes up to 20km above the ground and is capable of producing a data swath of up to
4km wide with 5m footprint. Flights also include high-resolution camera imagery. Other sensor data (e.g.
hyper spectral images) can be collected on request.
Since 2017, the sensor has been operating as a NASA Facility, providing low cost data to NASA investigators
and science missions. Contact us for details on how to include LVIS flights in your proposals.
In 2019, LVIS collected data to provide calibration for the recently-launched
Global Ecosystem Dynamics Investigation (GEDI) payload on the International Space Station. Measurements were
taken while underflying GEDI ground tracks in the southeastern United States and Central America, and area-mapping
was performed over the Coweeta Experimental Forest in North Carolina as well as the La Selva Biological Station in Costa Rica.
The AfriSAR field campaign in Feb-March 2016 collected data to help prepare and
calibrate four current and upcoming spaceborne missions for NASA, ESA and DLR.
LVIS was one of several airborne sensors and was used to collect surface topography,
vegetation height and structure data of several sites in Gabon, Africa.
Operation IceBridge images the polar regions of Earth to gather data on ice and glaciers.
LVIS flew in Greenland to gather data for this mission during Summer 2017.
Example of LVIS Scan and Beam Pattern
This image shows the LVIS scan and beam pattern. The unique LVIS scanning system generates this pattern that evenly and completely samples the surface below.
There are approximately 100 beams across the 2 km wide swath. The colors represent the surface elevation (blue is low, yellow/white is high).
The slight undulations at the top and bottom edges are a result of the aircraft roll. (Click image for full resolution)
