Introducjion 
The method described here may be used with only slight adaptations in 
all the photogrammetrie plotters whose principle is based on the recon 
struction of the geometric relations in the moment of exposure. It may 
be of use both in the orientation of sigle stereograms and in the space 
or plane aerotriangulation. 
The correct execution of air photographs has a great effect not only 
on the quality of the photogrammetrie map, but also on the quantity of 
time and work necessary for the outer orientation of aerial photographs 
and therefore on the costs of the photogrammetrie work. 
The practice shows, that the deviations of the camera axis from the 
verticality don’t exceed 2°, the deviations of the flight track from 
the straight line are n 1 % /where n « f l . the length 
and d - the sag of the strip/, the angles of swing are not greater 
than 3° and the proposed flight height may be kept with the accuracy of 
- 10 metres. The other elements of the air photographs may be not con 
sidered, because neither the forward nor the lateral overlap are of 
importance for the prpblem to be dissussed here.

The whole problem may be divided in the three main parts or cycles, 
constituting the orientation of aerial photographs on the autographs.
