Any unwanted disturbance affecting a measurement (as of a frequency band), especially that which degrades the information-bearing quality of the data of interest. Noise determines the precision with ...

return beam vidicon (RBV)

Aerospace; Satellites

As used on Landsat 1 and 2, a camera system which operated by shuttering three independent cameras simultaneously, each sensing a different spectral band in the range of 0.48 to 0.83 µm. The RBV ...

ancillary

Aerospace; Satellites

Auxiliary; accessory. in remote sensing, ancillary data are secondary data, pertaining to the area or classes of interest, such as topographic, demographic, or climatological data. Ancillary data may ...

radiometric reflective band calibration: radiance

Aerospace; Satellites

Calibration equations to convert unitless values from an optical satellite imager in Digitals Numbers (DNs) to engineering or scientific units such as at-satellite radiance or spectral radiance. ...

calibration parameter file

Aerospace; Satellites

Computer files of fixed parameters used in the ground processing system to convert raw uncalibrated bits from a spacecraft imager to radiometrically calibrated, artifact-reduced and ...

orthorectified

Aerospace; Satellites

Describing an image in which image displacements due to tilt and relief have been removed.

panchromatic

Aerospace; Satellites

Describing films or detectors that are sensitive to broadband electromagnetic radiation (the entire visible part of the spectrum). Landsat 7 has a 15 m "panchromatic" band that extends into the ...
