Questionnaire B deals with instruments available for student exercises (it was 
  
    
   
    
   
    
   
   
     
   
   
   
   
   
    
advised not to enumerate pocket stereoscopes, mirror stereoscopes, sketchmasters and 
similar instruments), and with the practical training of the students, For the latter the 
exercise subjects were grouped in a certain way and it was asked to indicate the number 
of hours spent on each subject group by the students on the average. 
These subjects of the exercises were: 
Tests for binocular vision, measurements with parallax bar, exercises in stereoscopic 
transfer of points, 
Exercises in relative orientation of pairs of photographs. 
Absolute orientation and plotting exercises (different types of instruments and different 
plotting scales). e | eo 
Aerial triangulation (including adjustment and computation of coordinates): 
a. with analogue instruments, 
b. with comparator types of instruments. 
c. other types of aerial triangulation (e.g. slotted templet triangulation, radial 
triangulation). 
Rectification. 
Checking instruments (grid measurements, camera calibration). 
Exercises in photographic laboratory, compilation of mosaics. 
Exercises in terrestrial and non topographic photogrammetry.
