Theia picker

Theia-picker enables to download efficiently theia products. In particular, it can download selected files from remote archives (e.g. one specific spectral band).

Quickstart

Installation:

pip install theia-picker

Perform searches and downloads. Entire archives can be downloaded, or files can be retrieved individually, without downloading the whole archive contents:

from theia_picker import TheiaCatalog

# Download bands 4 and 8 from a Sentinel-2 Level 2A product
cat = TheiaCatalog("credentials.json")
feats = cat.search(tile_name="T31TEJ", start_date="14/01/2021", level="LEVEL2A")
for f in feats:
    f.download_files(matching=["FRE_B4.tif", "FRE_B8.tif"], download_dir="/tmp")

Theia-picker computes checksums for archives (MD5) and individual files (CRC32) to ensure that they match the versions provided by the catalog and avoiding unnecessary requests. Read the documentation to know more.
