Installation
************

`xsar` relies on gdal_ and other shared libs, that are not provided by pip.
So insallation in a conda_ environement is recommended.


conda install
#############

1) Install mamba

For a faster installation and less conflicts between packages, it is better to install
xsar with mamba

.. code-block::

    conda create -n xsar
    conda activate xsar
    conda install -c conda-forge mamba

2) Install xsar (this won't include the readers)

.. code-block::

    mamba install -c conda-forge xsar


3) Add optional dependencies (readers)

- Add use of Radarsat2 :

.. code-block::

    mamba install -c conda-forge xradarsat2


- Add use of Sentinel-1

.. code-block::

    mamba install -c conda-forge xarray-safe-s1


- Add use of RCM

.. code-block::

    pip install xarray-safe-rcm


pip install
