Glossary for Geospatial Science

brightness:  The physical property indicating how much electromagnetic radiation is being reflected or radiated by a chosen point.  Brightness is similar to the HIS property of Intensity, and is used in the HBS color model.  Brightness is also the property computed from Landsat MSS or TM images by Kauth’s greenness, brightness, wetness transformations.  (See also: HBS, HIS.)
