Welcome! This repository provides guides, short how-tos, and tutorials to help users access and work with data from the Global Ecosystem Dynamics Investigation (GEDI) mission. All Jupyter notebooks and scripts should be functional, however, changes or additions may be made. Contributions from all parties are welcome.
The Global Ecosystem Dynamics Investigation (GEDI) mission aims to characterize ecosystem structure and dynamics to enable radically improved quantification and understanding of the Earth's carbon cycle and biodiversity. GEDI Level 1 and Level 2 Data Products are distributed by the Land Processes Distributed Active Archive Center (LP DAAC) and Level 3 and Level 4 Data Products are distributed by the ORNL DAAC.
Search for and download GEDI Version 2 data products via a graphical user interface (GUI) using NASA EarthData Search or programmatically using NASA's Common Metadata Repository (CMR), earthaccess python package, or Harmony API.
- GEDI L1B Geolocated Waveform Data Global Footprint Level - GEDI01_B.002
- GEDI L2A Elevation and Height Metrics Data Global Footprint Level - GEDI02_A.002
- GEDI L2B Canopy Cover and Vertical Profile Metrics Data Global Footprint Level - GEDI02_B.002
Instructions for setting up a compatible environment for working with GEDI data are linked to below.
Clone or download the GEDI-Data-Resources repository.
- Download
- To clone the repository, type
git clone https://github.com/nasa/GEDI-Data-Resources.gitin the command line.
Content in this repository is divided into Python and R tutorials/scripts. The tutorials walk you through workin with GEDI data step by step while the scripts are command line executables.
