On opening the session, the President announced that presented and invited papers would be divided amongst 
the various sessions, upon the discretion of the Chairmen. The exceptions would be 2 papers on cadastral 
purposes, and 2 on semantic information, due on July 26 and July 29. 
After a few explanatory remarks on the arrangement of the programme, the President appointed a Resolutions 
Committee composed of: A. van der Weele, H. Jerie, G. Petrie, G. Konecny, B. Dubuisson and J. Kure. 
The proceedings of the Commission IV symposium in Delft in September 1970 were discussed. 
The report of Commission IV not having arrived, its discussion was postponed. 
Editor's Note: The Report is included with the Invited Papers.

Planning Session 
Two Invited Papers were presented: A.J. Brandenberger, ** Macro-economic Investigations into Photogramme- 
tric Mapping Activities", and H.G. Jerie, Planning of Photogrammetric Projects’’. 
The figure quoted, that the world's economy suffers a loss of between 6 and 10 billion dollars per year due to 
inadequate maps, was questioned. Since this would be largely dependent on the rate of development of the 
countries concerned, the speaker admitted that the figures were estimates. One of the inputs used was a research 
project carried out by a consulting firm on behalf of the USGS, where it was assessed that every dollar invested 
in mapping saves three dollars. 
A query referred to the use of photogrammetry to locate underground resources. It was concluded that these 
natural resources cannot be located directly, although photogrammetry can supply an inventory on existing 
and potential resources areas. 
In the discussion of the water areas of the world, the speaker confirmed that his progress figures of practically 
0% only refer to mapping the continental shelves, and not to all water areas. The urgent need to establish 
mapping programmes for off-shore exploration and exploitation was emphasized, together with the necessity 
of developing new sensor techniques, although a side-looking sonar equipment is available for underwater 
mapping. 
The speaker's graphs were then queried, as to whether these are based on actual surveys of national economy, 
and whether they could be further quantified. The curves were merely theoretical speculations, but the audience 
was invited to come up with concrete values. The fact, that the graphs show that maps are, in general, 
out-of-date after 50 years, was questioned, since, particularly in urban areas, maps are probably out-of-date 
after 5 years. 
Discussion on Invited Paper of H.G. Jerie: “Planning of Photogrammetric Projects"*. 
It was suggested that a computer programme, preferably in the form of a system of sub-routines, should be 
developed for planning. Commercial air survey companies have, in general, to cost projects practically every 
two days, which implies that all alternatives are not always examined. In particular, the smaller companies 
would be interested in obtaining a general programme package which would greatly relieve senior 
management of a part of their present tasks.
