Remote sensing
Non-spectral hue
Earth science; Remote sensing
A hue which is not present in the spectrum of colours produced by the analysis of white light by a prism of diffraction grating. Examples are brown, magenta, and pastel shades.
Training site
Earth science; Remote sensing
Area of terrain with known properties or characteristics that is used in supervised classification.
Mercury
Earth science; Remote sensing
U. S. programme of one-man, earth-orbiting spacecraft in 1962 and 1963.
Thermal model
Earth science; Remote sensing
Mathematical expression that relates thermal and other physical properties of a material to its temperature. Models may be used to predict temperature for given properties and conditions.
Tracking and Data Relay Satellite (TDRS)
Earth science; Remote sensing
Geostationary satellite used to communicate between ground receiving stations and satellite such as Landsat.
Ground-control point
Earth science; Remote sensing
A geographic feature of known location that is recognisable on images and can be used to determine geometric corrections.
Roughness
Earth science; Remote sensing
In radar, the average vertical relief of a small-scale irregularities of the terrain surface. Also called surface roughness.
