Figure 4- Orientation results of Left image 
As a shown on figure Root mean square error of Right image 
is RMS Y=0.329m, RMS X=0.491m ,RMS XY= 0.591m and 
for left image is RMS Y=0.313 m, RMS X=0.543 m, RMS 
XY= 0.627 m. Residuals of ground control points for both 
images is founded minimum 0.02 m and maximum 0.90m. 
In test some GCP’ s used as check point, results are;

4.1.3Comparison of Results 
After DLT stereo restitution of images and orthophoto 
production with two different DEM has been carried out by 
Digital Photogrammetric Systems in GDLRC. Comparative 
results between coordinate differences of photogrammetric 
restituted and digitized from satellite images feature points 
are shown below. For comparison well identified feature 
points are chosen and blunders were eliminated. 
1) Coordinate differences between feature points from 
orthophoto which is produced by DTM via stereo 
images, from satellite images and photogrammetric 
restitution for 4b area.
