Are there tolerances for absolute orientation? 
Are records about orientation written and in which 
way /single form, book/? 
Plotting. 
Specify methods used /G= graphical, N= numerical, 
Asanalytical/ for map scales: 
1 500 : G N A 
1 : 1 000 : G N A 
is =: 2000: — 1: 8 2 506; G N A 
1 : 5 000 I N A 
1: 10:000 : G N A ) 
1 : 20.000= 1 125 000 3 G N A 
other scales 3 G N A 
Checking. 
In which way is accuracy of plotting checked? 
/in the office, in the field, etc./? 
Are there tolerances for planimetric accuracy of 
points? 
Are there tolerances for heights of points? 
Are there tolerances for contours? 
Were those tolerances based upon: 
Theoretical analyses? 
Experimental plotting? 
Statistics? j 
Map user's requirements? 
7. Were the tolerances quoted above published in books or di- 
rectives /specify /? 
8. Which of the problems mentioned are at present being solved 
in your country? 
9. What other facts do you consider to be important for specifi- 
cation of tolerances and criteria? 
Note ; Map and photo scale is to be quoted where necessary or 
useful.
