y- Comparison of the results determined geodetically and photogrammetrically 
After the geodetic coordinates of the new points were received, they were com- 
pared with the coordinates determined photogrammetrically. 
The systematic part of the differences was subtracted and then the root mean 
square values of the differences between photogrammetric and geodetic coordi- 
nates were computed. Table 5 gives the results of the comparison.

Some points are missing from the comparison. For 8 of the points marked on the 
air photographs (127, 177, 406, 407, 408, 414, 150, 155) geodetic coordinates 
were not received. Five of them (177, 406, 407, 408, 414) were targeted points
