About this dataset
NASA GEDI lidar global forest canopy height and structure at 30m resolution from the International Space Station.
NASA's Global Ecosystem Dynamics Investigation (GEDI) provides high-resolution lidar measurements of forest canopy height, vertical structure, and aboveground biomass at 30m resolution. GEDI operated from the International Space Station (2019-2023), collecting billions of lidar waveforms over temperate and tropical forests between 51.6°N and 51.6°S.

FAQ
What is the spatial coverage of GEDI?
GEDI collected measurements between 51.6°N and 51.6°S latitude, covering most of the world's tropical and temperate forests. The boreal zone north of 51.6°N is not covered.
What vegetation metrics does GEDI provide?
GEDI provides canopy height (RH metrics at percentiles), canopy cover, leaf area index, total biomass, and vertical profile metrics from full-waveform lidar returns.
