Global Ecosystem Dynamics Investigation (GEDI) High resolution laser ranging of Earth’s forests and topography from the International Space Station (ISS)

The Global Ecosystem Dynamics Investigation (GEDI) instrument is a full-waveform lidar installed on the International Space Station that produces detailed observations of the 3D structure of Earth’s surface. GEDI's three lasers precisely measure forest canopy height, canopy vertical structure, and surface elevation.

Jun 14, 2016 · Global Ecosystems Dynamics Investigation (GEDI ) is a NASA-run Earth Ventures Instrument (EVI) mission. Installed on the International Space Station (ISS) in December 2018, scientific analysis of the data has been led by Professor Ralph Dubayah at …

GEDI makes precise measurements of forest canopy height, canopy vertical structure, and surface elevation. GEDI radically improves our ability to understand important atmospheric and water cycling processes, biodiversity, and habitat. GEDI has been deployed on the International Space Station (ISS) since 2018.

Dec 5, 2018 · Focused on tropical and temperate forests from its vantage point on the International Space Station (ISS), GEDI uses lidar to provide the first global, high-resolution observations of forest vertical structure.

Aug 25, 2023 · GEDI（Global Ecosystem Dynamics Investigation）卫星是美国国家航空航天局（NASA）开展的一项地球观测任务。GEDI卫星的主要目标是获取全球各地森林和陆地生态系统的三维结构和动态信息，以帮助科学家更好地了解地球生态系统的变化和功能。

Aug 10, 2021 · On the International Space Station (ISS), 254 miles up, orbiting the Earth once every 90 minutes, GEDI uses waveform Lidar to record elevation and canopy data. Three lasers split into four beams (firing 242 times per second) are dithered to 8 tracks, 6 meters apart, with 25 meter footprints every 60 meters.

Global Ecosystem Dynamics Investigation (GEDI, pronounced / ˈdʒɛdaɪ /) is a NASA mission to measure how deforestation has contributed to atmospheric CO 2 concentrations. [1][2] A full-waveform LIDAR was attached to the International Space Station to provide the first global, high-resolution observations of forest vertical structure.

Apr 22, 2024 · The Global Ecosystem Dynamics Investigation (GEDI) instrument will begin its return to operations on the International Space Station (ISS) on Monday, April 22—which, fittingly, is also Earth Day.

Dec 17, 2018 · The Global Ecosystem Dynamics Investigation, or GEDI, uses advanced laser technology to reveal the makeup of remote forest ecosystems around the globe. Its measurements of the height of leaves, branches, trees, and shrubs below its path will help scientists map the structure of forests and better understand how ecosystems are storing or ...
