Global Ecosystem Dynamics Investigation (GEDI)

Overview

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 was funded as a NASA Earth Ventures Instrument (EVI) mission. It was launched to the International Space Station in December 2018 and became operational in March 2019.

Level 1B, Level 2A, and Level 2B data from GEDI are available from the Land Processes DAAC ( https://lpdaac.usgs.gov/ ). Gridded Level 3 GEDI data will be available from ORNL DAAC beginning in mid-2020, with Level 4 data to follow in early 2021.
