Disk space issue
################

First run
*********

iota2 requires original image data for the first run as mandatory information is extracted from them.

For example:

* original projection
* original resolution
* ...

Next run
********

iota2 can use already preprocessed data.
This requires that interpolation parameters do not change: same spectral resolution, same projection.
Only the spatial resampled data are stored and required, then the temporal resolution can be
changed without issues.

After run
*********

As described in the :ref:`classification_output_tree_structure`, ``classif`` directory contains per
tile and per region maps which are merged in ``final`` directory.
If you do not need these intermediate maps, they can be removed to free up disk space.

Input data
**********

If you used the ``write_reproject_resampled_input_dates_stack`` parameter, iota2 will stack all
bands inside a stack in a ``XXX_FRE_STACK.tif`` file.
If you are using these stack files as inputs and do not need to change the working resolution,
the individual bands (``_FRE_B2.tif``, ``_FRE_B3.tif``...) can be removed to free up disk space.
