Sen2Chain
=========

Sen2Chain is a simple utility written in Python 3 to download and process Sentinel-2 images.

It uses the `sentinelsat <https://github.com/sentinelsat/sentinelsat>`_ and `peps_download <https://github.com/olivierhagolle/peps_download>`_ packages to find and download data, and ESA's `Sen2Cor <http://step.esa.int/main/third-party-plugins-2/sen2cor/>`_ processor to perform atmospheric, terrain and cirrus correction.

Main features:

* downloading of L1C (top of atmosphere) products from Scihub and PEPS mirrors;
* processing of L1C to L2A (bottom of atmosphere) products;
* computing of radiometric indices;
* time series extraction of thoses indices;
* full automatization of the above features.

All these features can be launched in multiprocessing.
