Measure of the sensitivity of photographic film to light. Larger numbers indicate higher sensitivity.

detectability

Earth science; Remote sensing

Measure of the smallest object that can be discerned on an image.

dwell time

Earth science; Remote sensing

Time required for a detector IFOV to sweep across a ground resolution cell.

interactive processing

Earth science; Remote sensing

Method of image processing in which the operator views preliminary results and can alter the instructions to the computer to achieve desired results.

thermal IR image

Earth science; Remote sensing

Image acquired by a scanner that records radiation within the thermal IR band.

shuttle imaging radar (SIR)

Earth science; Remote sensing

L-band radar system deployed on the space shuttle. The synthetic aperture radar experiments were carried aboard the NASA space shuttle in 1981 and 1984.
