2. Problem analysis: Establishment of à general system model 
2.1. Product specifications 
We still start with the assumption that the task of the planner consists of design- 
ing a photogrammetric procedure meant to satisfy a given set of product specificat- 
ions in the most efficient (economical) way possible under the prevailing circum- 
stances. 
The most important items of such product specifications are given in table 1 below: 
  
d. Boundaries of project area 
2. Type of producti: 
Photomosaics and orthophotomosaics a 
Photomaps with annotation b 
Line maps with symbols C 
Digital data (with or without plot) a 
3. Map scale . a bic 
4. pheet-size, sheet layout, projection, grid a b c 
: Br Märgital information ES a . abc 
6. Type.of qualitative information to be presented, 
and symbols to be used (legend) bc 
T. Type of relief presentation (e.g. contours, spot heights) bc 
8. Accuracy of metric information (planimetry and height) & bcd 
9. Specifications concerning photographic image-quality a b 
10. Form of final feproduction (transparency, paper, etc.) abe 
T. Distribution of required digital information (regular 
or irregular grid, profiles or type of objects) 
12. Form of digital data (tape, cards, codes, etc.)
