Required

Requests python package to perform web queries https://requests.readthedocs.io/en/master/user/install/

python -m pip install requests

This code does requests to Copernicus Open Access Data Hub Service (DHUS) which requires authorization. To be able to do anything with it you have to register on https://scihub.copernicus.eu/dhus/#/home and replace AUTH = (‘DHUS_username’, ‘DHUS_password’) in S3_loader/config.py with that credentials.

An alternative NASA mirror is used to download offline (LTA) products unavailable on DHUS. It also requires registration on https://ladsweb.modaps.eosdis.nasa.gov/profile/#app-keys and replacement of DAAC_API_KEY = ‘DAAC-API-KEY’ in S3_loader/config.py with that api key.

Optional

For pixel extraction

• Sentinel Application Platform (SNAP) with Sentinel-3 toolbox is required http://step.esa.int/main/download/snap-download/

• shapely package (for Windows from wheel is recommended) https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely

All operations require database connection, to view the SQLite database with GUI and export tables as csv you may use https://sqlitebrowser.org

from S3_loader import S3Loader
api = S3Loader(db_path=DATABASE_PATH)
