Spectral signature
From Biocrawler, the free encyclopedia.
Spectral signatures are measurements of the percentage of solar reflectance as a function of wavelength (electromagnetic spectrum). The measurements are made with a spectrometer.
This instrument is equipped with a fibre optic pistol that is capable of receiving light reflected by a target. Calibration spectral signatures are collected in order to apply an empirical correction to the digital images (airborne or satellite imagery).
