The results of the calculations have been shown that while the increase in mx, my and mz is In cl 
very slow for the different values of a and p between 0-45 degrees, this increase is fast for the coorc 
values between 45-90 degrees (see Table 2). If it is taken into account that the change in the the t 
object distance from point to point is negligible in close range measurement, for the same system, objec 
the errors in the object space coordinates depend on angles a and ß. Base-Object distance ratio appr« 
is an important criterion in terrestrial photogrammetry and the convergent case is preferred to the can t 
normal case of photogrammetry to increase the base length in the analytical method. Because the of ho 
horizontal angle will increase with a longer base length and a shorter object distance, an optimal certo: 
base-object distance ratio should be considered (for example B/Z-2/1) in close range 
measurements with theodolite.
