Terms of reference of WGs 
  
The terms of reference of each WG are more closely described in Table 1. 
WG 2 and 5 have had the character of study groups, and they have not per- 
formed any uniform closely controlled experiments. They are generally con- 
cerned with the advancement of the technologies concerned. WGs 1, 3 and 4 
have in addition carried out empirical studies using real or simulated data. 
Symposia, meetings and publications 
  
The Symposium of the Commission lll was held in Otaniemi, Finland, June 7 - 
11, 1982. The theme was ''Mathematical Models, Accuracy Aspects and Quality 
Control". There were 121 participants from 23 countries. Altogether 63 papers 
were submitted for the Symposium, and they are printed in the International 
Archives of Photogrammetry, Vol. 24 - 111, parts 1 and 2. Part 1 was pub- 
lished before and part 2 after the Symposium. Part 2 contains e.g. all late 
papers and the records of the Technical Sessions. 
The programme of the Symposium consisted of 10 technical sessions with 46 
lectures, technical tours to three photogrammetric organizations, and a 
social programme. 
Wg 1, together with the OEEPE Commission A, organized a seminar on 'Mathemat- 
ical Models for Assessing Gross and Systematic Errors at Geodetic-Photogram- 
metric Point Determination" in Stuttgart, FRG, November 26 - 27, 1981. More 
than 50 participants attended. The proceedings are to be published. 
A Workshop and Business Meeting of WG 2 on ''On-Line Photogrammetric Triangu- 
lation" was arranged in Ottawa, Canada, May 17 - 19, 1983. Nearly 20 WG mem- 
bers and other participants took part. 
An International Colloqium of WG 3 on ''Mathematical Aspects of Digital Elev- 
ation Models' was held in Stockholm, Sweden, April 18 - 20, 1983. It had 
over 30 participants. The papers presented are published in a publication of 
the Department of Photogrammetry of the Royal Institute of Technology, Stock- 
holm, 1983. 
WG 5 held a Specialist Work-Shop on 'Pattern Recognition in Photogrammetry'' 
in Graz, Austria, September 27 - 29, 1983. There were approximately 80 par- 
ticipants. The lectures presented were distributed to the participants in the 
Work-Shop.
