The human eye qualitatively measures three colors blue green and red in the visible portion of the electromagnetic spectrum when viewing the environment. The human eye-brain combination is a powerful observing system however it generally provides a non-quantitative perspective of the local environment. Imaging spectrometer 335 2008 by Taylor Francis Group LLC 336 High-Performance Computing in Remote Sensing instruments typically measure hundreds of colors spectral channels across a much wider spectral range. These hundreds of spectral channels are recorded quantitatively as spectra for every spatial element in an image. The measured spectra provide the .
