spectral transformations  

Définition

  • Optical Earth remote sensing sensors record the reflected solar radiation in multiple discrete spectral channels, producing a spectral signature for each picture element in a remote sensing image. The amount of reflected energy depends on the physical and chemical nature and status of the object's surface and is a function of the scanned wavelength of the electromagnetic spectrum.
