Global Ecosystem Dynamics Investigation (GEDI)

The Global Ecosystem Dynamics Investigation (GEDI) is a satellite-based mission that uses laser technology to measure the Earth's forests and land surfaces in high detail. By emitting laser pulses toward the ground and analyzing the reflected signals, GEDI creates precise 3D maps of forest structure, including tree height, canopy density, and biomass. This information helps scientists understand how ecosystems change over time, assess carbon storage, and inform climate change models. Essentially, GEDI provides vital data to monitor the health and growth of our planet’s forests and land ecosystems from space.
