Remote sensing
Range resolution
Earth science; Remote sensing
In radar images, the spatial resolution in the range direction, which is determined by the pulse length of the transmitted microwave energy.
Airborne imaging spectrometer (AIS)
Earth science; Remote sensing
Along-track multispectral scanner with spectral bandwidth of 0. 01 m.
Polarisation
Earth science; Remote sensing
The direction of orientation in which the electrical field vector of electromagnetic radiation vibrates.
Grid format
Earth science; Remote sensing
The result of interpolation from values of a variable measured at irregularly distributed points, or along survey lines, to values referring to square cells in a rectangular array. It forms a step ...
Median philtre
Earth science; Remote sensing
A spatial filter, which substitutes the median value of DN from surrounding pixels for that recorded at an individual pixel. It is useful for removing random noise.
Cathode ray tube (CRT)
Earth science; Remote sensing
A vacuum tube with a phosphorescent screen on which images are displayed by an electron beam.
Scan skew
Earth science; Remote sensing
Distortion of scanner images caused by forward motion of the aircraft or satellite during the time required to complete a scan.
