GEDI’s precise measurements of the height and vertical structure of forest canopy, along with the surface elevation, will greatly advance our ability to characterize important carbon and water cycling processes, biodiversity, and habitat. The mission is led by the University of Maryland, College Park, and the instrument was built and tested at NASA's Goddard Space Flight Center.GEDI observes nearly all tropical and temperate forests using a self-contained laser altimeter on the International Space Station. GEDI has the highest resolution and densest sampling of any lidar ever put in orbit. This has required a number of innovative technologies to be developed at NASA Goddard.GEDI has three lasers that produce 8 parallel tracks of observations. Each laser fires 242 times per second and illuminates a 25-meter footprint on the surface over which 3D structure is measured. Each footprint is separated by 60 meters along the track, with an across-track distance of about 600 m between each of the 8 tracks. GEDI is expected to produce about 10 billion cloud-free observations during its nominal 24-month mission length.With these observations, GEDI will provide answers to how deforestation has contributed to atmospheric CO2 concentrations, how much carbon forests will absorb in the future, and how habitat degradation will affect global biodiversity. This data is of immense value for forest and water resource management, carbon cycle science, and weather prediction.For more information about GEDI: https://gedi.umd.edu || ", "release_date": "2018-10-09T08:00:00-04:00", "update_date": "2025-05-14T00:21:55.331276-04:00", "main_image": { "id": 399729, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a013000/a013090/GEDI_beauty_waveform_still_print.jpg", "filename": "GEDI_beauty_waveform_still_print.jpg", "media_type": "Image", "alt_text": "Animation of the Global Ecosystem Dynamics Investigation (GEDI) instrument, as installed on the ISS, showing the three lasers, which are split into 4 beams that alternate to give 8 footprints across a 4.2 km swath when they hit the ground.

The animation depicted here is the beginning of LOLA's mapping project and shows the lunar south pole through digital elevation map data collected by the LOLA instrument during the spacecraft commissioning phase. During the commissioning phase, LRO was in a highly elliptical orbit coming closer to the lunar south pole than the north pole. Furthermore, since LOLA uses laser pulses to measure the surface, the accuracy of its measurements are greatly affected by the instrument's distance to the surface. This is why there is virtually no data of the lunar north pole, and much better coverage of the south pole. The topographic data shown here is currently processed to show at approximately 30 meters per pixel.The colors in this animation depict the relative heights of the lunar surface with respect to the surface mean.
