Spectral and color images

All the images show ice-covered parts of Isfjorden

The sample image is divided in 15 spectral images
each covering 12,4 nm. It should be noted that the
wave interval can be equal to the bandpass of 5 nm
thus obtaining a higher degree of spectral information.  

The following images are showing RGB-composite
images, selected from three of the 15 spectral images.
Each in its respective color range. For clarity the
images has been expanded by a factor of four
in the vertical direction.
