Earth science; Remote sensing
Mathematical philtre that treats all orientations of linear features equally.
Radar scattering coefficient
Earth science; Remote sensing
A measure of the back-scattered energy from a target with a large area. Expressed as the average radar cross section per unit area in decibels (dB). It is the fundamental measure of the radar ...
Resampling
Earth science; Remote sensing
The calculation of new DN for pixels created during geometric correction of a digital scene, based on the values in the local area around the uncorrected pixels.
Ultraviolet (UV)
Earth science; Remote sensing
Ultraviolet region of the electromagnetic spectrum ranging in wavelengths from 0. 01 to 0. 4m.
