Earth science; Remote sensing

Geographic orientation of a line given as an angle measured in degrees clockwise from north.

line drop out

Earth science; Remote sensing

The loss of data from a scan line caused by malfunction of one of the detectors in a line scanner.

Planck's Law

Earth science; Remote sensing

An expression for the variation of emittance of a blackbody at a particular temperature as a function of wavelength.

contrast enhancement

Earth science; Remote sensing

Image-processing procedure that improves the contrast ratio of images. The original narrow range of digital values is expanded to utilize the full range of available digital values.
