the combined bundle block adjustment is highest when the 
two periods of imageries are at the same scale. Comparing 
table 3 with table 2, we can learn that the exterior 
orientation elements of new imageries obtained in this 
paper are close to the ones calculated by the conventional 
bundle block adjustment with GCPs. And the accuracy of 
3D coordinates of all photogrammcetric points is identical 
between the two methods. 
accuracy will decrease apparently when small-scale fixed 
imageries are used to calculate the exterior orientation 
elements of large-scale imageries in the same area. The 
planimetric accuracy of densification points doesn't 
change much, but the height accuracy decreases terribly. 
In spite of the fact that the adjusted results still meet the 
specification for 1:1,000 topographic mapping in 
mountainous area. The coordinate residuals of check 
points are less than 5.0m in planimetry and 3.0m in height
