Code for GEDI, ICESat GLAS and ICESat2 ATLAS data processing, for the Global Delta project.
This code defines functions for creating a workflow for querying, downloading, and subsetting GEDI and ICESat data This code was based on publicly available code and resources.
- ICESat query and download: Download script from the NSIDC webpage. Example: https://nsidc.org/data/GLAH06/versions/34 in 'download data' click in 'Download script'.
- GEDI query: GEDI finder web service https://lpdaacsvc.cr.usgs.gov/services/gedifinder
- GEDI subsetting: GEDI_Subsetter.py code by Cole Krehbiel https://git.earthdata.nasa.gov/projects/LPDUR/repos/gedi-subsetter/browse/GEDI_Subsetter.py
- Earth Data login setup code EarthdataLoginSetup.py created by Cole Krehbiel https://git.earthdata.nasa.gov/projects/LPDUR/repos/daac_data_download_python/browse/EarthdataLoginSetup.py
