6 CONCLUSIONS 
Table 4. Results of blocks adjustment 
  
Point accuracy matching ranging from 0.22 to 0.32 pixel size has been achieved in both aerial triangulation methods. It 
is similar to the theoretical values possible to obtain by analytical aerial triangulation method. The results of semi- 
automatic and automatic AT are similar. Lower then expected accuracy of exterior orientation parameters in AAT is 
due to higher value of standard deviation of measurements of photo coordinates in AAT. 
Lower quality of aerial photographs in block No.2 has adversely influenced the achieved accuracy, but still it was 
possible to run MATCH-AT. 
MATCH-AT is a powerful automatic digital aerial triangulation tool. It generates many additional tie points that 
strengthen the geometry of the block.
