The MIVIS hyper-spectral scanner is a modular instrument 
composed of four spectrometers which simultaneously measure 
the electromagnetic radiation from the Earth’s surface by 
recording 102 spectral bands: 
e 20 in the visible spectral region (0.43-0.83jum) 
e 8 in the near infrared one (1.15-1.55pm) 
e 64 in the middle infrared one (2.0-2.5um) 
e 10 in thermal infrared (8.2-12.7pm). 
Bands acquired by the 3rd spectrometer are, for the used 
images, damaged and not useful.
