scale

Earth science; Remote sensing

Ratio of distance on an image to the equivalent distance on the ground.

synthetic stereo images

Earth science; Remote sensing

Stereo images constructed through digital processing of a single image. Topographic data are used to calculate parallax.

interpretation

Earth science; Remote sensing

The process in which a person extracts information from an image.

bit

Earth science; Remote sensing

Contraction of binary digit, which in digital computing represents an exponent of the base 2.

reflectance

Earth science; Remote sensing

Ratio of the radiant energy reflected by a body to the energy incident on it. Spectral reflectance is the reflectance measured within a specific wavelength interval.
