Overview GEDI’s gridded biomass and forest structure products have a core resolution of 1 km, based on aggregating footprints within these cells. However, even after four years in orbit, some cells still lack GEDI tracks. Many stakeholders need gap-free maps at finer spatial resolutions. To address this, we combine GEDI’s [...]

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. GEDI radically improves our ability to characterize important carbon and water cycling processes, biodiversity, and habitat. GEDI was originally deployed [...]

Old Forest Ecosystems Old forests are delicate and complex ecosystems. Commonly referred to as “old-growth” both scientifically and colloquially, these forests usually contain very old trees and conditions that require a long time to develop in the absence of intensive human impact. Old-growth forest conditions were commonplace in North America [...]

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. The data latency depends on the level of the data product. Lower level data products (L1 & [...]

“Return Of The GEDI: Scanning The Amazon With Lasers” “La misión que escanea la Amazonia con rayos láser para saber cuánto carbono almacena” … This story, written by Naiara Galarraga Gortázar, was published in both English and Spanish in a dual production by Science Friday and América Futura (El País).

Access dataset here Summary This dataset contains Global Ecosystem Dynamics Investigation (GEDI) Level 4C (L4C) Version 2 predictions of the Waveform Structural Complexity Index (WSCI) and estimates of prediction intervals for each footprint estimate at 95% confidence. In this version, the granules are in sub-orbits. The algorithm setting group selection [...]
