Remote sensing
Principal-component (PC) image
Earth science; Remote sensing
Digitally processed image produced by a transformation that recognises 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.
Look-up table (LUT)
Earth science; Remote sensing
A mathematical formula used to convert one distribution of data to another, most conveniently remembered as a conversion graph.
Cross-track scanner
Earth science; Remote sensing
Scanner in which a faceted mirror rotates about a horizontal axis to sweep the detector IFOV in a series of parallel scan lines oriented normal to the flight direction.
Geostationary orbit
Earth science; Remote sensing
An orbit at 41 000 km in the direction of the Earth's rotation, which matches speed so that a satellite remains over a fixed point on the Earth's surface.
Photographic IR
Earth science; Remote sensing
Short-wavelength portion (0. 7 to 0. 9 m) of the IR band that is detectable by IR colour film or IR black-and-white film.
