cordance with the method of least squares gave a standard error of 
unit weight of the coordinates of 2.1 mm. Then the coordinates of all 
points from 1956 were transformed to the system of 1957 with the aid 
of the determined transformation data. The transformed coordinates 
were then compared with the coordinates from 1957 and the discrepan- 
cies (the corrections) to the coordinates of 1956 could be computed. In 
Table 1 the coordinates x, y and elevations z of the points for verti- 
cal photography from the measurements in 1957 are demonstrated. The 
columns dx, dy and dz are the corrections to the coordinates from the 
measurements in 1956.
