Getting Started with GEDI L2B Version 2 Data in Python

This tutorial demonstrates how to work with the Canopy Cover and Vertical Profile Metrics (GEDI02_B.002) data product.

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. The GEDI instrument produces high resolution laser ranging observations of the 3-dimensional structure of the Earth. GEDI is attached to the International Space Station and collects data globally between 51.6 N and 51.6 S latitudes at the highest resolution and densest sampling of any light detection and ranging (lidar) instrument in orbit to date. The Land Processes Distributed Active Archive Center (LP DAAC) distributes the GEDI Level 1 and Level 2 Version 1 and Version 2 products. The L1B and L2 GEDI products are archived and distributed in the HDF-EOS5 file format.

Use Case Example:

This tutorial was developed using an example use case for a project being completed by the National Park Service. The goal of the project is to use GEDI L2B Version 2 data to observe tree canopy height, cover, and profile over Redwood National Park in northern California.

This tutorial will show how to use Python to open GEDI L2B Version 2 files, visualize the sub-orbit of GEDI points (shots), subset to a region of interest, visualize GEDI canopy height and vertical profile metrics, and export subsets of GEDI science dataset (SDS) layers as GeoJSON files that can be loaded into GIS and/or Remote Sensing software programs.

Before Starting this Tutorial:

Setup and Dependencies

It is recommended to use Conda, an environment manager to set up a compatible Python environment. Download Conda for your OS here: Once you have Conda installed, Follow the instructions below to successfully setup a Python environment on Linux, MacOS, or Windows.

This Python Jupyter Notebook tutorial has been tested using Python version 3.7. Conda was used to create the python environment.

If you do not have Jupyter Notebook installed, you may need to run:

conda install jupyter notebook

Having trouble getting a compatible Python environment set up? Contact LP DAAC User Services at:

If you prefer to not install Conda, the same setup and dependencies can be achieved by using another package manager such as pip.

Example Data:

This tutorial uses the GEDI L2B observation from June 19, 2019 (orbit 02932, sub-orbit 02). Use the links below to download the files directly from the LP DAAC Data Pool:

You will need to have the file above downloaded into the same directory as this Jupyter Notebook in order to successfully run the code below.
