I. The detection of the features was easy than 35K 
stereo models, 
2. The intensity of the data made difficult working in the 
existing software and hardware. € 
The following results were obtained from the comparison of 
25K stereo compilation against 35K stereo compilation:

excessive amount of details detected, 
There were some confusion between narrow electric 
lines and telephone lines, 
3. Nearly all the details that cannot be seen in 35K could 
be seen, i.e. tracks, paths, narrow roads, telephone
