6. Production lines -i t : 
Photogrammetric production concerns the control network densification, 
terrain relief modelling (e.g. contouring), image transformations (e.g. 
orthophoto), mapping (i.e., terrain features’ modelling), and some other 
(figure 14). 
Each production line is defined by the corresponding operating proce- 
dure(s). AMP is a variant of digital mapping. 
For integration of the production lines, their mutual relationships are 
most essential.

Fig. 14: Photogrammetric production lines and their interrelationships 
The flow of basic information and control data from one line to another 
should be adequately channeled and timed in order to attain efficient 
overall production. 
Optimal flow provides balanced distribution of the work load and thus 
exploits the available resources. 
Each production line can be represented by several process variants, each 
of which can be partitioned into preparation, production, and quality 
control. 
7. Information and data 
Information systems contain integrated and thus structured sets of basic 
information and control data. They imply relationships which should be 
compatible and properly described. 
Structures include the relationships, and are implemented by means of the 
classification schemes. Structures and the procedures (including algo- 
rithms) should be mutually adjusted for all process stages (figure 10). 
Compatibility concerns the structures of basic information and control 
data. The latter include specifications for input and output and data for 
process control [8]. 
Description format for information and data is defined by the classifica- 
tion schemes (for input and output; [8]). 
VI CONCLUSION 
The properties of an AMP system can be differentiated according to tech- 
nical and management aspects. Some properties, however, concern both 
categories. 
The technical properties can be summarised as follows: 
— AMP is feasible for differential mapping if: 
. terrain relief has not changed significantly, 
. required accuracy is not extremely high. 
It is not suitable for:
