which 
became more and 
more important for the plotting process at the beginning 
of the 60ies the working title for Commission II from 
1964 - 1972 is "Theory, Methods and Instruments of Plot 
ting"* During this period photogrammetry is more and more 
faced with equipment for data acquisition and orthophoto 
production, with analytical plotters and procedures of 
image correlation. 
A new quality for photogrammetry starts at the beginning 
of the 70ies forced by the development of Remote Sensing 
and the further advancement of computer technology. The 
International Society for Photogrammetry did not change 
only the name into ISPRS but also the classic analogue 
stereoplotter more and more lost its importance. Well 
known and then revolutionary was the display of more than 
half of a dozen of analytical plotters during the Helsinki 
Congress in 1976 which was the beginning of their intro 
duction into practice. From this time analogue plotters
