For example, this is typically how one determines, from some distance, whether a material on the ground is grass (green), soil (brown), or asphalt (black). To accomplish this, most digital cameras (along with the human eye) produce images that are comprised of three different colors, called spectral bands: red, green, and blue. The combination of these bands enables material discrimination. Working in the same way, but on a much larger scale, hyperspectral imaging sensors produce images that are comprised of hundreds of spectral bands. This combination of bands enables …
