Summary 
The three new optical systems for mono and stereo interpreta 
tion of aerial photos and satellite images described can, of 
course, be used for other kinds of image and sensor interpreta 
tions. 
The television connection or integrated television camera provi 
ded with all systems is equipped with the corresponding inter 
face by which means the photo material can always be digitized. 
This, of course, improves the interpretation. 
In short, whether analog or digital image interpretation is requi 
red, we cannot imagine doing without the RK 820, the Zoom 
Sight 20 X, and the stereo sensor SMI 2 as the newest evaluation 
aids in the field of photogrammetrical interpretation. 
Digital Image processing by means of 
the SMI 2 
a) Trinned area of vertical Image, 
original size of the image area 
2 mm x 3 mm 
b) Terrain model made according to 
this pattern as judioial evidence 
c) Digital image reversion as additional 
judioial evidence
