Remote sensing

The process of using aerial sensor technologies to detect and classify objects on Earth both on the surface, and in the atmosphere and oceans by means of propagated signals.

Contributors in Remote sensing

Remote sensing

Contrast

Earth science; Remote sensing

The ratio between the energy emitted or reflected by an object and its immediate surroundings.

Synthetic stereo images

Earth science; Remote sensing

Stereo images constructed through digital processing of a single image. Topographic data are used to calculate parallax.

Lidar

Earth science; Remote sensing

Light intensity detection and ranging, which uses lasers to stimulate fluorescence in various compounds and to measure distances to reflecting surfaces.

Reflectance

Earth science; Remote sensing

Ratio of the radiant energy reflected by a body to the energy incident on it. Spectral reflectance is the reflectance measured within a specific wavelength interval.

ISO index

Earth science; Remote sensing

Index of the International Standards Organization, designating film speed in photography. Higher values indicate higher sensitivity.

Interpretation

Earth science; Remote sensing

The process in which a person extracts information from an image.

Scale

Earth science; Remote sensing

Ratio of distance on an image to the equivalent distance on the ground.
