Release of GEDI Subsetter Data Prep Script

On January 21, 2020, the LP DAAC released Level 1B – Level 2 GEDI data products to the public, including Level 1B Geolocated Waveform Data (GEDI01_B), Level 2A Elevation and Height Metrics Data (GEDI02_A), and Level 2B Canopy Cover and Vertical Profile Metrics Data (GEDI02_B). GEDI granules are stored as HDF5 files encompassing an entire International Space Station (ISS) orbit, which are currently available through the LP DAAC Data Pool and NASA’s Earthdata Search. On February 10, 2020, the LP DAAC released the GEDI Finder web service, enabling spatial querying of GEDI files. However, spatial and layer subsetting of GEDI full orbits, as well as exporting subsets into GIS and Remote Sensing-friendly output formats has been a challenge for GEDI users.

The LP DAAC is pleased to announce the availability of a data prep script called the GEDI Spatial and Band/layer Subsetting and Export to GeoJSON (GEDI Subsetter) script. The GEDI Subsetter is a command line executable python script that allows users to spatially subset GEDI files by submitting a GeoJSON or bounding box (Upper Left, Lower Right) region of interest. Users can also perform layer subsetting by defining specific GEDI datasets to be included in their subset output. The script will extract the desired layers, clip to the region of interest, and export as a GeoJSON file of points (shots) that can easily be loaded into GIS and/or Remote Sensing software for further visualization and analysis.
