Home Page - GEDI GEDI observes nearly all tropical and temperate forests using a self-contained laser altimeter on the International Space Station
Mission Overview - GEDI 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
Products Overview - GEDI GEDI science data products include footprint and gridded data sets that describe the 3D features of the Earth These data products are assigned different levels, which indicate the amount of processing that the data has undergone after collection
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
Access - 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
