1• Introduction 
For many years in tile Institut of Photogrammetry and 
Cartography of Warsaw Technical University photo- 
grammetric methods have been applied in solution 
of different type of engineering tasks* The majority 
of them were solved to the order of the scientific 
departments of the branches of industry. The analy 
tical» analogue-numerical and graphical methods 
of photogrammetry have been applied and selection 
of method depended upon the character of engineer 
ing tasks and actual photogramme trie eguipment. 
The comparison of the costs of photogramme- 
tric measurements in. relation to other methods is 
difficult, because of their experimental character. 
In some applications the measurement is possible 
only by the utilization of photogrammetry because 
geodetical or physical methods can not be used. 
For this reason, in this paper these economic advan 
tages of photogrammetric methods which are connected 
with the following features» will be shown: 
- the objectivism of photographic registration, 
- the archival value of the photographs which 
allows for the repetition of the measurement, 
- the possibility of noncontact measurement of the 
examined object, 
- the significant limitation of fieldwork time, 
- an arbitrarily short time of the imaging which 
allows for measurement of speedy processes* 
2* Technical and economic aspects of photogrammetric 
measurement 
According to the economic advantages 
of photogrammetric measurements and the type of 
engineering tasks the presented experiments will 
be divided into six groups-
