Detailed explanation-1: -The x-axis displays the bands and wavelengths of the electromagnetic spectrum for each band. When plotting Boxes, Boxes and Mean Lines, and Consolidated Mean Lines, the x-axis is determined by the number of bands in the image, not the wavelength. Each tick on the x-axis shows the band name where that data was derived.
Detailed explanation-2: -A spectral signature is a plot of the amount of light energy reflected by an object throughout the range of wavelengths in the electromagnetic spectrum. The spectral signature of an object conveys useful information about its structural and chemical composition.
Detailed explanation-3: -Spectral signatures of rocks and mineral provide information on their chemical composition and crystal properties, grain size and roughness over a wide range of wavelengths from the visible to the thermal infrared.
