Remote sensing
Isotherm
Earth science; Remote sensing
Contour line connecting points of equal temperature. Isotherm maps are used to portray surface-temperature patterns of water bodies.
Photographic UV
Earth science; Remote sensing
Long-wavelength portion of the UV band (0. 3 to 0. 4 m) that is transmitted through the atmosphere and is detectable by film.
Far range
Earth science; Remote sensing
The portion of a radar image farthest from the aircraft or spacecraft flight path.
Distortion
Earth science; Remote sensing
On an image, changes in shape and position of objects with respect to their true shape and position.
Densitometer
Earth science; Remote sensing
Optical device for measuring the density of photographic transparencies.
Thematic mapper (TM)
Earth science; Remote sensing
A cross-track scanner deployed on Landsat that records seven bands of data from the visible through the thermal IR regions.
Coherent radiation
Earth science; Remote sensing
Electromagnetic radiation whose waves are equal in length and are in phase, so that waves at different points in space act in unison, as in laser and synthetic aperture radar.
