2. The Multispectral Scanner as Spectroradiometer: 
In order to understand the method for calculating the spectral 
reflectance factors from the MSS-data some technical details 
of the Bendix M2S, which has been used within the German Remote 
Sensing Programme, should be briefly discussed (figure 1) (2).

The MSS continuously scans the overflown earth surface whereby 
each line consists of 803 picture elements. The field of view is 
100 degrees, the IFOV 2,5 mrad, the dynamic resolution is 8 bit, 
namely 256 grey levels are available for each pixel and for each 
channel. The position and the width of the spectral bands are 
given in figure
