i.emissivity
i.emissivity --help
i.emissivity input=name output=name [--overwrite] [--help] [--verbose] [--quiet] [--ui]
Flags:
- --overwrite
- Allow output files to overwrite existing files
- --help

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...
