although the work horses in production until today have 
lost their scientific importance. 
New terms like Hardware and Software arose and plotting 
as processing of image data became the main link in the 
image measuring procedures. 
Consequently Commission II due to the resolutions of the 
Ottawa Congress at the International Congresses in 1976 
and 1980 was acting under the designation "Instrumenta 
tion for Data Reduction". Influenced by digital image 
processing technology which then mainly was applied in 
remote sensing in 1980 the commission name was extended 
by the term "Data Analysis", the now valid name for our 
Ilnd Commission "Systems for Data Processing and Reduct 
ion was chosen in 1984. 
The terms instrument or plotter no more appear in the 
headline. The change of interest and the new task of the 
Technical Commission II become still more clearer if the 
areas of interest of the Working Groups are analyzed. 
Such groups can be established by the Technical Commission 
for providing initiative in technical and scientific pro 
gress. 
For the first time within Commission II during the period 
from 1964 - 1968 a Working Group for the "Elaboration of 
Standard Tests for Photogrammetric Restitution Instruments" 
and a Intercommission Working Group on "Fundamental Prob 
lems in Photogrammetry" were organized. For the next four 
year period from 1968 - 1972 a new Working Group on "Auto 
mated and Analytical Instruments" was established, where 
as the work on Standard Tests went on until 1976. From 
1972 - 1976 we already notice 3 Working Groups solving 
special tasks within the Commission II. Additional to the 
before mentioned 2 Working Groups a third one is occupied 
with "Orthophoto Equipment". A systematic splitting up of 
Commission Work started in 1976 when 4 new Working Groups
