NASA’s Global Ecosystem Dynamics Investigation (GEDI) project was launched on December 5, 2018 and is attached to the International Space Station. GEDI is a full-waveform light detection and ranging (lidar) instrument that produces high-resolution laser ranging observations of the 3D structure of the Earth’s surface. GEDI collects data globally between 51.6° N and 51.6° S latitudes at the highest resolution and densest sampling of any lidar instrument in orbit to date. GEDI aims to characterize ecosystem structure and dynamics to enable radically improved quantification and understanding of Earth’s carbon and water cycles, habitat, and biodiversity. 

NASA’s Land Processes Distributed Active Archive Center (LP DAAC) has begun distributing GEDI Level 1B and Level 2 products, which include geolocated full waveform measurements (L1B), elevation and height metrics (L2A), and canopy cover and vertical profile metrics (L2B), all provided as ~30 m footprints. In addition to learning about the mission, tune in to learn about GEDI Level 1B-2 products and where to find additional resources for getting started with GEDI data.
