Wavelength (symbol λ) = 1/frequency. In general, the mean distance between maximums (or minimums) of a roughly periodic pattern. Specifically, the shortest distance between particles moving in the ...

emission

Aerospace; Satellites

With respect to electromagnetic radiation, the process by which a body emits electromagnetic radiation as a consequence of its kinetic temperature only.

bidirectional reflectance

Aerospace; Satellites

A unitless measure of the ratio of incoming to outgoing radiation created from converting a radiometrically calibrated image to an innate characteristic of the target being observed. After removing ...

planetary albedo

Aerospace; Satellites

A unitless measure of the ratio of outgoing to incoming solar radiation created by converting a radiometrically calibrated image observed from orbit to the apparent reflectance of the planet being ...

space oblique mercator (SOM)

Aerospace; Satellites

A variation on the basic Mercator map projection based on the dynamics of satellite motion. The movements of the Landsat platform, sensors, and the Earth, expressed as functions of time, are used to ...

universal transverse mercator (UTM)

Aerospace; Satellites

A widely used map projection employing a series of identical projections around the world in the intermediate latitudes, each covering 6° of longitude and oriented to a meridian. The UTM projection ...

sun-synchronous

Aerospace; Satellites

An Earth satellite orbit in which the orbital plane remains at a fixed angle with respect to the Sun, precessing through 360° during the period of a year. Landsat satellites are in near-polar orbit ...
