Remote sensing
Blind spot
Earth science; Remote sensing
The point of the optic nerve to the retina where no radiation is detected by the eye.
Scanner distortion
Earth science; Remote sensing
Geometric distortion that is characteristic of cross-track scanner images.
Image striping
Earth science; Remote sensing
A defect produced in line scanner and pushbroom imaging devices produced by the non-uniform response of a single detector, or amongst a bank of detectors. In a line-scan image the stripes are ...
IR colour photograph
Earth science; Remote sensing
Colour photograph in which the red-imaging layer is sensitive to photographic IR wavelengths, the green-imaging layer is sensitive to red light, and the blue-imaging layer is sensitive to green ...
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 utilise the full range of available digital values.
Anomaly
Earth science; Remote sensing
An area on an image that differs from the surrounding, normal area. For example, a concentration of vegetation within a desert scene constitutes an anomaly.
Passive remote sensing
Earth science; Remote sensing
Remote sensing of energy naturally reflected or radiated from the terrain.
