interpretation equipment and with the stereoplotting 
machine. 
Of the 6 spectral ranges of the MKF-6 it was channel 4 
(640...680 nm) which proved to be most suitable for inter- 
pretation in most object categories of complex thematic 
mapping at the scale 1:200 000, 
- Larger villages and settlements are clearly visible 
with regard to their boundaries and inner structures. 
- Conspicuous single buildings, such as churches and 
railway stations, can be identified. 
- Industrial plants, airports, dumps of building material, 
lignite mines etc. can be well recognized. 
= The road network with highways, motorways and 
communication roads can be compiled in more detail than 
it is represented in the general map 1:200 000, 
- The road net and the network of railway communications 
can be identified by the contrast of the contiguous diffe- 
vegetation covers or built-up areas. rent 
- Large rivers and ponds, canals, inland lakes and coastal 
lines can be well demarcated, but can be still better 
interpretated in channel 6, 
- Forests and agricultural areas are well visible and are 
characterized by clear demarcations between them. 
The santrawents Interpretation and restitution of cosmic 
photographs in the original format (55 mm x 81 mm) can be 
carried out considerably more effectively by pre-interpreta- 
in enlargements scaled up to 1:200 000 of the channels 4 tion 
(640,..680 nm) and 6 (790...890 nm). 
The graphic photogrammetric stereoplotting from space 
photographs of the scales 1:2000 000 to 1:2 700 000 for the 
map scales 1:100 000 to 1: 200 000 can be carried out onkhe 
STEREOMETROGRAPH G stereoplotting machine. This precision 
stereoplotter with a range of calibrated focal length from 
85 mm to 310 mm and a 7-times viewing magnification allows
