Eyes on Earth Episode 82 - Introduction to GEDI
Eyes on Earth podcast
Eyes on Earth is a podcast on remote sensing, Earth observation, land change and science, brought to you by the USGS Earth Resources Observation and Science (EROS) Center. In this episode, we learn about the purpose of the GEDI mission on the International Space Station and what is being learned from it.

Summary: The Global Ecosystem Dynamics Investigation, or GEDI, instrument on the International Space Station acquires lidar waveforms to observe the Earth’s surface in 3D. The GEDI lidar measures the height and density of objects, so it provides information such as surface elevation and tree canopy height and cover. The NASA Land Processes Distributed Active Archive Center (LP DAAC) at EROS provides storage and distribution of GEDI data. In this episode, we’ll take a look at the purpose of the GEDI mission, how the instrument works, and how GEDI data are being used to understand things like carbon dynamics in forests.
Guests: Ralph Dubayah and Laura Duncanson, University of Maryland and the GEDI mission
Host: Jane Lawson
Producer: Tom Adamson
