spectral vegetation index
Earth science; Remote sensing
An index of relative amount and vigor of vegetation. The index is calculated from two spectral bands of AVHRR imagery.
layover
Earth science; Remote sensing
In radar images, the geometric displacement of the top of objects toward the near range relative to their base.
Stefan
Earth science; Remote sensing
Boltzmann law-States that radiant flux of a blackbody is equal to the temperature to the fourth power times the Stefan-Boltzmann constant.
aerial magnetic survey
Earth science; Remote sensing
Survey that records variations in the earth's magnetic field.
pulse length
Earth science; Remote sensing
Duration of a burst of energy transmitted by a radar antenna, measured in microseconds.
granularity
Earth science; Remote sensing
Graininess of developed photographic film that is determined by the texture of the silver grains.
