Supporting data collected on the ground, and information derived therefrom, as an aid to the interpretation of remotely sensed data. Ground data typically pertain to weather, soils, and vegetation ...

coherent noise

Aerospace; Satellites

Systematic periodic noise in image or calibration data which can be characterized in terms of frequency, phase and amplitude. It is often quantified using Fourier analysis. Coherent noise is usually ...

nadir

Aerospace; Satellites

That point on the celestial sphere vertically below the observer (i.e. the point on the Earth directly below an orbiting satellite), or 180° from the zenith.

color

Aerospace; Satellites

That property of an object which is dependent on the wavelength of the light it reflects or, in the case of a luminescent body, the wavelength of the light it emits. If, in either case, this light is ...

spatial resolution

Aerospace; Satellites

The ability of an imaging system to distinguish closely spaced objects in the subject area. Can be expressed as the spacing, in line-pairs per unit distance, of the most closely spaced lines that can ...
