INAUGURAL PLENARY SESSION 
tions have already started over strips of Italian territory 200 kilometers long. Com 
missions B and C have a wealth of material from the German polygon of Reichenbach, 
over which the Institut für Angewandte Geodäsie of Frankfurt has established a large 
quantity of highly precise control points. The observations of both these Commissions 
will start very shortly. They will find wide application in the enquiries into analytical 
procedures, not only for aerial triangulation but also for the numerical plotting. 
I wish to underline the enormous quantity of photographic material accumulated 
by the OEEPE during the last few years, it concerns strips examined under carefully 
studied conditions all having a large number of control points. This is really most 
precious and valuable material, and I want to express the warmest thanks to those 
countries, institutions, and bodies which have so splendidly contributed to its prepara 
tion. 
Two more Commissions were set up after the Stockholm Congress: Commis 
sion E now beginning its activity for small-scale plotting, and Commission F devoted 
to fundamental problems. Commission F has had to cope with some problems which 
have turned out to be far more difficult than was previously thought, but some of the 
results already obtained have been of the utmost importance. 
At last, with the appearance of Commission F, a group for numerical photo- 
grammetry has been set up and is now chiefly engaged in the critical examination of 
calculation procedures for analytical triangulation. The OEEPE field of enquiries 
has gradually become larger and larger, requiring further research for new problems. 
Present-day technique also puts new instruments at our disposal, and ideas are evolved 
very rapidly. 
Work is enormous and requires the intensive application of all possible resources. 
Let me then renew the wish and hope for an ever closer collaboration amongst 
the various research institutes so as not to waste precious energy. In particular, let me 
wish for an ever increasing and cordial co-operation between the ISP and the 
OEEPE, since untold benefit may thus be bestowed upon photogrammetry. 
The President: I thank you Professor Solaini on behalf of the International 
Society for Photogrammetry for the trouble you have taken to come and address us here 
this morning on this important occasion. We are well aware that the OEEPE is 
carrying out work which can contribute much to the advancement of photogrammetry 
and to our knowledge of its techniques, which, after all, is the principal object of 
this Society. We welcome all the co-operation you can give us and every contribu 
tion you can make. May I add one word to that. Italian is Professor Solaini’s mother 
tongue; but Italian is not one of our official languages. I should like to say how much I 
admire the manner in which he has got his tongue round the English language. 
I now come to next Item, which is, indeed, a sad one. I circulated the Member 
Societies asking for information about those whom they might have lost through 
death during the last four years. I have a list of some twenty or thirty names of 
important photogrammetrists who have died since the last congress in Stockholm. I do 
not propose to read them out to you, but we would offer our sincere condolences, not 
only to the Member Societies but also to their relatives for their loss. The Council have 
decided that formalities of this kind should not be prolonged, that if we mention any 
names they should be confined to principal officers and past principal officers and 
honorary members of the International Society. There is only one name I would bring 
before you. It is that of a person whom you knew very well and whose obituary 
appeared in our Journal, Photogrammetria. It is, Dr Bauersfeld. I am sure you would 
wish me to mention his name on this occasion. All has been done which is reasonable 
and possible in this world to keep his memory fresh.
