Remote sensing data are considered hyperspectral when the
data are gathered from numerous wavebands, contiguously
over an entire range of the spectrum (e.g., 400–2500 nm). Goetz
(1992) defines hyperspectral remote sensing as “The acquisition
of images in hundreds of registered, contiguous spectral bands
such that for each picture element of an image it is possible
to derive a complete reflectance spectrum.” However, Jensen
(2004) defines hyperspectral remote sensing as “The simultaneous
acquisition of images in many relatively narrow, contiguous
and/or non contiguous spectral bands throughout the
ultraviolet, visible, and infrared portions of the electromagnetic
spectrum.”..
