The Global Ecosystem Dynamics Investigation (GEDI), a full-waveform light detectionand ranging system, translated the energy into a continuous waveform and recordedthe signals chronologically for enabling geometric analysis of the vertical structure ofvegetation. The National Aeronautics and Space Administration has used the land,vegetation, and ice sensor (LVIS) airborne laser altimeter system to measure terrain,tree heights, and vegetation carbon stocks in designated areas. The effectiveness ofthe collected LVIS data has been proven in mapping forest structures and biomass intropical and temperate systems. Based on the successful achievements of LVIS, theGEDI aimed to establish a global range of forest data needed to analyze and predictthe carbon cycle and climate change. The GEDI was launched aboard the SpaceX-16in 2018 and successfully attached to the International Space Station (ISS) for a 2-yearmission, but now extended until March 2023. Since being mounted on the ISS, GEDImeasured over 10 billion cloud-free surface observations within the range of 51.6°Nto 51.6°S. In this paper, GEDI mission is introduced, and the process of downloading,refining the GEDI level-2A product focused on Gyeonggi Province is outlined. KCI Citation Count: 0
