"Hyperspectral sensors collect several, narrow spectral bands from the visible, near-infrared, mid-infrared, and short-wave infrared portions of the electromagnetic spectrum. These sensors typically collect 200 or more spectral bands, enabling the construction of an almost continuous spectral reflectance signature. Furthermore, narrow bandwidths characteristic of hyperspectral data permit an in-depth examination of earth surface features which would otherwise be ‘lost’ within the relatively coarse bandwidths acquired with multispectral data."
