Output Format
=============

Data organization
^^^^^^^^^^^^^^^^^

The data are organized in a gridded data structure, i.e. data cubes.
The tiles manifest as directories in the file system, and the images are stored within. For mosaicking, use force-mosaic.

.. seealso:: 

  Check out this `tutorial <https://davidfrantz.github.io/tutorials/force-datacube/datacube/>`_, which explains what a datacube is, how it is parameterized, how you can find a POI, how to visualize the tiling grid, and how to conveniently display cubed data.


Data Cube definition
^^^^^^^^^^^^^^^^^^^^

The spatial data cube definition is appended to each data cube, i.e. to each directory containing tiled datasets, see :ref:`datacube-def`.


File format
^^^^^^^^^^^

Refer to :ref:`hl-format` for details on the file format and metadata.


Naming convention
^^^^^^^^^^^^^^^^^

Following 21-digit naming convention is applied to all output files:

Example filename: 2017_IMPROPHE_IGS.tif
