The photographic scale is 1:30000. The area is the average 
heights ranging between 1200 m and 2000 m above sea level, 
generating large relief displacements. The DETM was generated 
from the photogrammetric restitution, with contour intervals of 2 
m (Figure 7). The size grid was 2 m. The aerial photography was 
scanned with an optical resolution of 1200 dpi. 
The results of the affine transformation, performed to determine 
the parameters of correspondence between the digital image (rows 
and columns) and the photographic image (system of photography 
in millimeters) are shown in the Table 1. The internal camera 
parameters obtained through DLT are shown in the Table 2.

The orientation parameters determined using the coordinates of all 
seven control points in both fiducial system and terrain system and 
the Eq 3 and 4, are shown in the Table 3. From these parameters, 
the DETM nodes were projected on the photographic image using 
the Eq. 3 and 4, obtaining the rectified image show in the Fig. 13. 
The stereomate corresponding is presented in the Fig. 12. Finally, 
the Figure 11 is an anagliph made with both images.
