READ MORE: https://svs.gsfc.nasa.gov/13090   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 [...]

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’s enables Earth to Action applications such as forest inventory and analysis, topography mapping, ecosystem services valuation, finance, etc. GEDI [...]

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 [...]
