PostgreSQL metadata database
============================
* TODO
GeoMultiSens interacts with a PostgreSQL database that contains all the satellite image metadata for all datasets that
can be processed. Apart from that, it contains system-wide configuration parameters and some statistical data.
The database consists of the following tables:
.. csv-table::
:header: "Table", "Description"
:widths: 10, 30
config, system-wide configuration parameters for GeoMultiSens
datasets, records of datasets supported by GeoMultiSens
footprints_sentinel2_granules, spatial footprints of Sentinel-2 granules
jobs, processing and analysis jobs and their attributes
mgrs_tiles, spatial footprints of MGRS (military grid reference system) tiles
mgrs_tiles_proc, records of already processed MGRS tiles
satellites, records of satellites supported by GeoMultiSens
scenes, records of satellite image metadata
scenes_proc, records of already processed satellite images
scenes_sentinel2, separate table for Sentinel-2 metadata
sensors, records of sensors supported by GeoMultiSens
spatial_ref_sys, records regarding the spatial reference system
stats_mem_usage_homo, memory usage statistics for different job configurations
subsystems, records of subsystems supported by GeoMultiSens
virtual_sensors, records of target sensors of the spectral and spatial homogenization

* Only those datasets that were correctly added to the local GeoMultiSens data storage before can be used to create
a new GeoMultiSens preprocessing job (see :ref:`ref__add_new_data_to_the_database`).
* You need to set the parameter `virtual_sensor_id` when creating a new processing job
to define which target sensor is used for spatial and and spectral homogenization.
Here is an overview of pre-defined target sensors:

20, Landsat-7
21, Sentinel-2A spectral bands at Landsat pixel grid
