.. _filling:

Filling
=======

This pipeline fills holes or masked regions in the DSM, using configurable interpolation or
reconstruction methods. 

Allowed inputs
--------------

This pipeline takes a single DSM as input, as explained in the :ref:`DSM input <input_dsm>` section.

.. warning::

  In order for filling to work, the DSM needs to have been generated with the dense match filling ``zero_padding`` method used during the `surface_modeling` pipeline.

Applications
------------

This pipeline uses the following applications : 

- :ref:`dem_generation <dem_generation_app>`
- :ref:`dsm_filling <dsm_filling_app>`
- :ref:`auxiliary_filling <auxiliary_filling_app>`

The DSM filling application can be called multiple times, as shown in the application's documentation page.
