Remote sensing

Radiant flux

Earth science; Remote sensing

Rate of flow of electromagnetic radiation measured in watts per square centimeter.

Intensity

Earth science; Remote sensing

In the IHS system, brightness ranging from black to white.

An image where the continuous variation in the property being sensed is represented by a continuos variation in image tone. In a photograph this is achieved directly by the grains of photosensitive ...

Instantaneous field of view (IV)

Earth science; Remote sensing

Solid angle through which a detector is sensitive to radiation. In a scanning system, the solid angle subtended by the detector when the scanning motion is stopped.

Mixed pixel

Earth science; Remote sensing

A pixel whose DN represents the average energy reflected or emitted by several types of surface present within the area that it represents on the ground; sometimes called a mixel.
