The result of Table 4 could be summarized as: 
RMS Error : 94.1256 m 
Average Error: -12.02 m 
Figure 11 shows the general view of the generated DTM. The 
black areas inside the image are the places that matching 
process was unsuccessful. 
For evaluating the DTM, the generated DTM subtracted from 
the provided DTM of the Area. The provided DTM as it was 
mentioned previously doesn't cover the entire images and the 
coverage is about 60-75%. Therefore, the evaluation has been 
done on the common area. Because of the non stability in the 
coastal line, the area for the comparison is selected as Figure 8. 
The difference image is shown in Figure 12.
