International Society for Photogrammetry 
Commission II Working Group 2 Invited Paper 
"Standard tests for photogrammetric plotters" 
by R. Burkhardt, Berlin 
1) Establishment of the working group 
The working group was established by recommendation of the 1964 congress 
in Lisbon; it was created on the initiative of the president of Commis 
sion II at the meeting of the different commission at the symposium of 
Commission II at Bad Godesberg on April 21, 1967 (/30/). 
The working group is to be made up of eight to ten members. Together 
with instrument manufacturers and users, it is to elaborate rules for 
periodic checks on the adjustment and operational condition of photo 
grammetric plotters. The members of the group are faced with the dif 
ficult task of representing higher interests (Manufacturers and users, 
theory and practice, national and international interests, etc.). 
The negotiations originally startet at Bad Godesberg led to the follow 
ing composition of the working group: 
1. Dipl.-Ing. 
2. Dipl.-Ing. 
3. Mr. 
4. Dr.-Ing. 
5. Ing.Geograph 
6. Dr.-Ing. 
7. Dr.-Ing. 
8. Dr.-Ing. 
9. Dr. 
10. Dipl.-Ing.

Group member No. 9 did not participate in the meetings and the members 
named under 3» 5 and 7 only took part in some meetings. In addition, 
detailed written comments were presented in reply to the circulars, the 
suggestions submitted by members of the group and the drafts prepared 
by the group. Due to the large amount of correspondence, the original 
plans for multi-lingual correspondence unfortunately had to be given 
up. 
A preliminary meeting and discussion of aims and intentions was held 
with limited attendance at Karlsruhe, following an invitation by the 
president of Commission II, Professor Schwidefsky. The programm agreed 
upon at that meeting was submitted to all members, discussed with them 
and drawn up in its final form, for which another four sessions were 
required, viz. 
1. on September 23, 
2. on January 12 and 13, 
3. on June 1 and 2, 
4. on October 2 and 3, 
1966 in Essen
