[remote sensing]
An image that measures a single, broad band of wavelength that spans across a wide range of the electromagnetic spectrum; for instance, it may span the entire visible spectrum, or a portion of the visible and the near-infrared. Because it is a single, wide band, what is measured is target brightness; objects shown appear in shades of gray.
