This tab allows for the combination of bands loaded in a :ref:`band_set_tab`.
This tool is intended for combining classifications in order to get a raster
where each value corresponds to a combination of class values.
Raster values must be integer type.
A combination raster is produced as output and the area of each combination is
reported in a .csv file.
This tool supports virtual raster output; if the output file name ends
with .vrt then the output is created as virtual raster composed of as many
.tif files as the number of CPU threads defined in
:ref:`system_processing`; for large rasters this can speed up the process.
