Remote sensing

Systematic distortion

Earth science; Remote sensing

Geometric irregularities on images that are caused by known and predictable characteristics.

Lens

Earth science; Remote sensing

One or more pieces of glass or other transparent material shaped to form an image by refraction of light.

Radiometer

Earth science; Remote sensing

Device for quantitatively measuring radiant energy, especially thermal radiation.

Hue

Earth science; Remote sensing

In the IHS system, represents the dominant wavelength of a color.

Slant-range image

Earth science; Remote sensing

In radar, an image in which objects are located at positions corresponding to their slant-range distances from the aircraft path. On slant-range images, the scale in the range direction is ...

Image dissection

Earth science; Remote sensing

The breaking down of a continuous scene into discrete spatial elements, either by the receptors on the retina, or in the process of capturing the image artificially.

Polar orbit

Earth science; Remote sensing

An orbit that passes close to the poles, thereby enabling a satellite to pass over most of the surface, except the immediate vicinity of the poles themselves.
