XIII CONGRESS OF INTERNATIONAL SOCIETY 
FOR PHOTOGRAMMETRY 
HELSINKI JULY 11-28, 1976 
GENERAL REPORT OF COMMISSION II 
President: Prof. Ing. G. Inghilleri 
Secretary: Prof. Ing. B. Astori 
According to the Articles of the International Society of Photogrammetry, the 2nd Com 
mission is concerned with developing "Instruments for the use of photogrammetric da- 
9... the main lines along which its activity develops from one congress to the next a 
re set up by the resolutions that I.S.P., i.e. the general meeting, approves at the 
end of each congress. 
The Commission activity can therefore be outlined by considering the resolutions that 
were passed at the end of the Ottawa conference in 1972. 
1) The first resolution recommended that work on "standard tests" should be carried 
on. In fact, in the four years 1968 to 1972 a Work Group had been established to 
set up the rules to be followedfor testing plotting equipment, so as to establish 
testing standards enabling safe and objective evaluations. This Work Group , hea- 
ded by Prof. M. Dohler from the University of Karlsruhe, reported to the Ottawa 
congress; on such occasion some problems were raised by the manufacturers as re- 
gards the following: 
a) need for establishing tests for analytical instruments; 
b) problems connected with the performance of somewhat complex tests by small or 
ganizations ; 
c) manufacturing, and relevant cost, of the special grids needed to carryout the 
tests. 
It was then decided that the Work Group on "Standard Tests" should continue their 
activity and improve the work made on the basis of what had emerged. 
In October 1974, on the occasion of Turin Symposium of the 2nd Commission , the 
Work Group held a general meeting. 
The second resolution dealt with the work on "automated and digitized instruments", 
and demanded that the advantages of digitizing stereo-plotting instruments should 
be examined, together with experts from the fourth Commission, if the case may be,
