|
|
|
|
|
|
|
|
.. code-block:: console
|
|
|
|
|
|
|
|
git clone https://framagit.org/jebins/sen2chain.git

Configuration
|
|
|
|
-------------
|
|
|
|
|
|
|
|
The configuration file is located at: ``~/sen2chain_data/config/config.cfg``.
|
|
|
|
This file (and corresponding path) is only created after the first sen2chain import in python.
|
|
|
|
|
|
|
|
Configure Sentinel-2 images library
|
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
At first launch default folders are created in ``~/sen2chain_data/data``. You can change the settings by editing the configuration file.
|
|
|
|
|
|
|
|
Sen2cor configuration
|
|
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
The full path to the sen2cor bashrc file is needed to process L1C to L2A.
|
|
|
|
e.g.: ``/home/user/Sen2Cor-02.05.05-Linux64/L2A_Bashrc``
|
|
|
|
|
|
|
|
Hubs logins
|
|
|
|
^^^^^^^^^^^
|
|
|
|
In order to dowload images, you need a login on the `PEPS <https://peps.cnes.fr/rocket/#/home/>`_ and `Scihub <https://scihub.copernicus.eu/dhus>`_ servers.
|
|
|
|
|
|
|
|
* The PEPS login and password must be stored in ``~/sen2chain_data/config/peps.txt`` like so:
|
|
|
|
|
|
|
|
.. code-block:: html
|
|
|
|
|
|
|
|
username password
|
|
|
|
|
|
|
|
* The Scihub login and password are stored in the configuration file.
|
