.. _sen2cor: Sen2Cor Configuration ---------------------------------- .. note:: If you want to process products from 2017 and before, you need to install previous versions of Sen2Cor and follow the guidelines :ref:`here <configure_sen2cor>`. This section focuses on Sen2Cor 2.12 configuration. 1. To configure sen2cor, you must first download the context data used for certain Sentinel-2 pre-processing steps here `ESACCI-LC package for SC module <https://earth.esa.int/eogateway/ftp/Sentinel-2/ESACCI-LC-L4-ALL-FOR-SEN2COR-2.10.tar.gz>`_ 2. Then, move or create symlink to Sen2Cor directory: .. code-block:: bash ~$ ln -s /path/to/ESACCI-LC-L4-ALL-FOR-SEN2COR-2.10/ESACCI-LC-L4-LCCS-Map-300m-P1Y-2015-v2.0.7.tif /path/to/Sen2Cor-02.12.03-Linux64/lib/python2.7/site-packages/sen2cor/aux_data/ ~$ ln -s /path/to/ESACCI-LC-L4-ALL-FOR-SEN2COR-2.10/ESACCI-LC-L4-WB-Map-150m-P13Y-2000-v4.0.tif /path/to/Sen2Cor-02.12.03-Linux64/lib/python2.7/site-packages/sen2cor/aux_data/ ~$ ln -s /path/to/ESACCI-LC-L4-ALL-FOR-SEN2COR-2.10/ESACCI-LC-L4-Snow-Cond-500m-MONTHLY-2000-2012-v2.4 /path/to/Sen2Cor-02.12.03-Linux64/lib/python2.7/site-packages/sen2cor/aux_data/ 2. Create or symlink DEM directory .. code-block:: bash ~$ ln -s /path/to/dem ~/sen2cor/2.12/dem 3. Update Sen2Cor configuration file ``nano ~/sen2cor/2.11/cfg/L2A_GIPP.xml`` .. code-block:: html <DEM_Directory>dem/srtm</DEM_Directory> <DEM_Reference>http://srtm.csi.cgiar.org/wp-content/uploads/files/srtm_5x5/TIFF/</DEM_Reference> <DEM_Terrain_Correction>FALSE</DEM_Terrain_Correction> # If you don't want DEM terrain correction 4. Update Sen2Chain config file ``nano ~/sen2chain_data/config/config.cfg`` .. code-block:: bash ~$ sen2cor_bashrc_paths = /path/to/Sen2Cor-02.12.03-Linux64/L2A_Bashrc 5. Then update Sen2Chain by using any method : .. code-block:: python >>> from sen2chain import Tile >>> Tile('40KCB').info
