Earth science; Remote sensing
Digitally processed image produced by a transformation that recognizes maximum variance in multispectral images.
reststrahlen band
Earth science; Remote sensing
In the IR region, refers to absorption of energy as a function of silica content.
image
Earth science; Remote sensing
Pictorial representation of a scene recorded by a remote sensing system. Although image is a general term, it is commonly restricted to representations acquired by non-photographic methods.
thermal conductivity (K)
Earth science; Remote sensing
Measure of the rate at which heat will pass through a material, expressed in calories per centimeter per second per degree Centigrade.
Rayleigh criterion
Earth science; Remote sensing
In radar, the relationship between surface roughness, depression angle, and wavelength that determines whether a surface will respond in a rough or smooth fashion to the radar pulse.
