Remote sensing
Range
Earth science; Remote sensing
In radar usage this is the distance in the direction of radar propagation, usually to the side of the platform in an imaging radar system. The slant range is the direct distance from the antenna to ...
Complementary colours
Earth science; Remote sensing
Two primary colours of light (one additive and the other subtractive) that produce white light when added together. Red and cyan are complimentary colors.
Saturation
Earth science; Remote sensing
In the IHS system, represents the purity of color. Saturation is also the condition where energy flux exceeds the sensitivity range of a detector.
Dielectric constant
Earth science; Remote sensing
Electrical property of matter that influences radar returns. Also referred to as complex dielectric constant.
Trade-off
Earth science; Remote sensing
As a result of changing one factor in a remote sensing system, there are compensating changes elsewhere in the system; such a compensating change is known as a trade-off.
Emulsion
Earth science; Remote sensing
Suspension of photosensitive silver halide grains in gelatin that constitutes the image-forming layer on photographic film.
Landsat
Earth science; Remote sensing
A series of unnamed earth-orbiting NASA satellites that acquire multispectral images in various visible and IR bands.
