This visualization depicts a global view of forest height data collected by the GEDI instrument aboard the International Space Station. Brown and dark green represent shorter vegetation. Bright green and white represent taller vegetation. This visualization uses data collected between April 2019 and April 2020. Height is exaggerated to depict variation at this scale.

The Global Ecosystem Dynamics Investigation (GEDI) produces high resolution laser ranging observations of the 3D structure of the Earth. GEDI’s precise measurements of forest canopy height, canopy vertical structure, and surface elevation greatly advance our ability to characterize important carbon and water cycling processes, biodiversity, and habitat.

GEDI’s data on surface structure are also of immense value for weather forecasting, forest management, glacier and snowpack monitoring, and the generation of more accurate digital elevation models. GEDI provides the missing piece – 3D structure – in NASA’s observational assets which enables us to better understand how the Earth behaves as a system, and guides the actions we can take to sustain critical resources.

The GEDI instrument is a geodetic-class, light detection and ranging (lidar) laser system comprised of 3 lasers that produce 8 parallel tracks of observations. Each laser fires 242 times per second and illuminates a 25 m spot (a footprint) on the surface over which 3D structure is measured. Each footprint is separated by 60 m along track, with an across-track distance of about 600 m between each of the 8 tracks. GEDI expected to produce about 10 billion cloud-free observations during its nominal 24-month mission length.

This is a closeup view of the GEDI forest height data collected for the west coast of the United States. Data is drawn on the globe over time, depicting how data coverage increases with each satellite pass. Brown and dark green represent shorter vegetation. Bright green and white represent taller vegetation. This visualization uses data collected between April 2018 and April 2019. Height is exaggerated to depict variation at this scale.
