LVIS Classic and Facility L1B and L2 data from ABoVE and GEDI Cal/Val 2019 are now available at NSIDC!


What is LVIS?

LVIS Logo

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 dm 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.


GEDI Cal/Val Products

GEDI Cal/Val 2019

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.

Flight trajectories and preliminary coverage maps are available on the data page, as well as a link to the L1B geolocated waveforms and L2 elevation and height products located at NSIDC.

AfriSAR 2016

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.


Recent LVIS Missions

ABoVE 2019

The Arctic-Boreal Vulnerability Experiment observes changes in forests, permafrost, and ecosystems in Canada and Alaska.

LVIS flew in Northwest Territories, Canada and Alaska to gather data for this mission during Summer 2019.

IceBridge 2017

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)

Where is LVIS?

Since LVIS is not currently on a mission, this map is showing a science flight from July 2019. This was a flight to map areas on the north slope of Alaska and Canada as a part of the ABoVE campaign. More results from this mission can be found here.
