Mission Overview - GEDI Mission Overview GEDI produces the first high resolution laser ranging observations of the 3D structure of the Earth GEDI makes precise measurements of forest canopy height, canopy vertical structure, and surface elevation
Home Page - GEDI GEDI observes nearly all tropical and temperate forests using a self-contained laser altimeter on the International Space Station GEDI’s data are of immense value for forest and water resource management, carbon cycle science, and weather prediction
Products Overview - GEDI GEDI data products are designed to answer key science questions on the role of ecosystem structure now and in the future GEDI science data products include footprint and gridded data sets that describe the 3D features of the Earth
Instrument Overview - GEDI GEDI is a full-waveform lidar instrument that makes detailed measurements of the 3D structure of the Earth’s surface Lidar is an active remote sensing technology (the laser version of radar) which uses pulses of laser light to measure 3D structure
Timeline - GEDI Timeline GEDI launched to the ISS on December 5th, 2018, to begin its 2-year mission of discovery The mission was extended twice After a period of hibernation on the ISS from March 2023 through April 2024, GEDI has returned to its original spot on the ISS to begin collecting data for years to come
ATBD Documents - GEDI Algorithm Theoretical Basis Documents (ATBDs) describe the physical theories, mathematical procedures and model assumptions applied in the calculation of geophysical quantities from laser altimetry measurements received by the GEDI instrument
Access - GEDI All GEDI data products are available for free download GEDI data products are available at different resolutions and time intervals Data latency times (that is the time lag between when data are acquired and when a particular product is available) are given below
GEDI Begins Its Next Journey On March 17th, 2023, the GEDI mission embarked on its next journey GEDI completed its first four years on orbit and is heading into storage on the ISS GEDI was powered down at 01:58 UTC
