# About
Sentinel2ProductIngestor is used to download earth observation data provided by the http://www.esa.int/Our_Activities/Observing_the_Earth/Copernicus/Sentinel-2 satellites and store it to Amazon S3.
At the moment there is not much else here than application pulling data from Sentinel Science Hub. Lots of effort was put into solving technical difficulties (e.g. Hub not working, transfer being interrupted, etc.) and ensuring reliability of the transferred data.
In the future we plan to add some further utils related to organisation of Sentinel archive.

# About the data
