WebFour-band frame imager with butcher-block filter providing blue, green, red, and NIR stripes (DOVE-R) Eight-band frame imager with butcher-block filter providing blue, green, red, red-edge, and NIR stripes (SuperDove) Spectral Bands: Coastal Blue: 431 - 452 nm. Blue: 465 – 515 nm. Green I: 513 - 549 nm. Green: 547 – 583 nm. Yellow: 600 - 620 nm Red edge refers to the region of rapid change in reflectance of vegetation in the near infrared range of the electromagnetic spectrum. Chlorophyll contained in vegetation absorbs most of the light in the visible part of the spectrum but becomes almost transparent at wavelengths greater than 700 nm. The cellular structure of the vegetation then causes this infrared light to be reflected becau…
