3. Compilation equipment_and_techniques 
The equipment systems and methods commonly used in photo- 
grammetry can in principle be employed for cartographic 
plotting from space photographs taken with the MKF-6. 
MKF-6 photographs can be restituted in the original format 
or with 2.4 times enlargement (& special equipment, the 
PPA Automatic Precision Enlarger is used for this purpose). 
Plotting can be performed by employing the following 
techniques: 
- rectification (with Rectimat C), 
- gtereoplotting (with Stereometrograph or Topocart and 
DZT Digital Drawing Table), 
- map revision (with Kartoflex), 
- differential rectification (with Topocart-Orthophot), 
- digital restitution (with Stecometer or Dicometer), 
- digital image processing (with image digitization) 
by the FEAG and BVS Image Processing System. 
In previous cartographic applications a great variety 
of interesting and important knowledge was gained. For example 
it was found that for mapping urban areas photographs of the 
spectral channel 4 were best suited for interpretation, 
while for the mapping of forests the channels 5 and 6 proved 
to be of advantage. 
A basic knowledge is that MKF-6 space photos meet the 
requirements of most mapping tasks at the scales 1:50000 
to 1:200000 (and smaller) both with regard to the interpre- 
tation capability and the geometric accuracy. 
4. Report on practical experiences 
In the practical work done so far it has been proved that 
when existing older maps (general map 1:200000 and topographic 
map 1:50000) were used for the stereoscopic interpretation 
or restitution of cosmic MKF-6 photographs at the photo 
scales 1:2 millions (from the Sayuz 22 space vehicle) or 
1:2.7 millions (from the Salyut 6 and Salyut 7 space stations) 
good results were achieved with the INTERPRETOSKOP C
