The Global Ecosystem Dynamics Investigation (GEDI) is a full-waveform lidar instrument aboard the International Space Station (ISS) that produces detailed observations of the 3-dimensional structure of the Earth’s surface. GEDI precisely measures forest canopy height, canopy vertical structure, and surface elevation, which enhances our understanding of global carbon and water cycle processes, biodiversity, and habitat. GEDI is the first spaceborne sensor to provide high resolution laser ranging observations optimized for lidar measurements of the Earth’s forests and topography. Data from GEDI is archived and distributed by the LP DAAC.
The (GEDI Data Resources GitHub repository) provides guides, short how-tos, and tutorials to help users access and work with GEDI data. In the interest of open science, this repository has been made public and is open to contributions. The repository is actively maintained by the LP DAAC. All resources should be functional; however, changes or additions may be made. We encourage users to periodically check the repository for resource updates.
Below are data use resources available for GEDI.
