       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       input=name [required]
           Name of the NDVI map [-]

       output=name [required]
           Name of the output emissivity layer


DESCRIPTION
       i.emissivity   calculates   the   emissivity  in  the  longwave  radiation  spectrum,  according  to  the
       semi-empirical equation related to NDVI by Caselles and Colles (1997), valid in the NDVI range of 0.16 to
       0.74.

       Estimation in the 8-14 micrometers range for sparse canopy...
