Remote sensing
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.
normal color film
Earth science; Remote sensing
Film in which the colors are essentially true representations of the colors of the terrain.
calibration
Earth science; Remote sensing
Process of comparing an instrument's measurements with a standard.
classification
Earth science; Remote sensing
Process of assigning individual pixels of an image to categories, generally on the basis of spectral reflectance characteristics.
Doppler principle
Earth science; Remote sensing
Describes the change in observed frequency that electromagnetic or other waves undergo as a result of the movement of the source of waves relative to the observer.
backscatter
Earth science; Remote sensing
In radar, the portion of the microwave energy scattered by the terrain surface directly back toward the antenna.
noise
Earth science; Remote sensing
Random or repetitive events that obscure or interfere with the desired information.
