knowl 
Ihe purpose of this questionnaire was to obtain 
edge about requirements upon planimetric and alti- 
metric accuracy of medium and large scale maps in diffe- 
rent countries in dependence upon conditions of mapping 
and to obtain knowledge about photogrammetric methods as 
they are actually used.
