accuracy needs in this stage of planning. By producing the 
necessary orthomaps it was possible to greatly facilitate the field 
work of the Metro planning teams and to support the in-office 
work of Metro lines design and imposition of Metro stations in 
their suitable locations. Nonetheless, the acquired images 
proved to be cost effective solution during the course of 
establishing the concept of the traffic study and decision making 
of the Metro network. At the same time satellite imagery 
constitutes correct and impressive technical basis for 
documentation and presentation of plans and technical solutions 
prepared through the traffic study. 
Both the accuracy and resolution are good enough that in the 
following planning phases the need for terrestrial geodesy will 
be limited to measuring only required areas. Moreover, the 
accuracy was sufficient enough to ensure the implementation of 
the Metro project in later phases.
