INAUGURAL PLENARY SESSION
on Tuesday, 6th September, 1960
The Secretary-General: As the Secretary-General of the International Society
for Photogrammetry, I have pleasure in calling to order this first General Assembly of
the Ninth Annual Congress for Photogrammetry. Pray silence for your President,
General Brown.
The President: We are honoured to have with us this morning a distinguished
Member of Her Majesty’s Government in the United Kingdom, the Rt Hon Earl Wal-
degrave, Parliamentary Secretary to the Minister of Agriculture and Food. He has very
kindly come here to open our proceedings, and I will now ask him to speak.
The Rt Hon Earl Waldegrave: I am very pleased and honoured to have been
asked to perform the opening ceremony of this, the Ninth Congress of the International
Society for Photogrammetry. It is, I believe, the first time that the Congress of this
Society has been held in Great Britain since the Society was formed in 1910. The Con
gress, as you know, is being held in this country at the invitation of The Royal Institution
of Chartered Surveyors and The British Photogrammetric Society, and has been
organised by a Congress Board working in close collaboration with the President and
the Secretary-General of the International Society for Photogrammetry.
I hope I may speak on behalf of all these Societies as well as on behalf of Her
Majesty’s Government in extending the warmest welcome to all the official Delegates
and visitors from many countries to this Congress.
Speaking as a layman, a politician, a Jack of all trades, I must confess that until
1 was asked to open this Congress I knew very little about the process of photogram
metry, but even a layman can see surely that this process has an infinite number of
possible applications. I was vastly interested to learn of the increasing part that photo
grammetry is playing in the lives of us all.
The first and, 1 suppose, still the most important application of photogrammetry
is the taking of measurements from photographs - this, as 1 understand, is the correct
definition - and is an aid to surveying and map-making. In a rapidly-developing world
the need for accurate and up-to-date maps surely needs no stressing. For centuries,
of course, the classical methods of surveying depended on taking measurements, both
linear and angular, on the ground, and these methods must necessarily be slow and
deliberate, particularly, perhaps, when you are mapping deserts or jungles where the
physical difficulties, including transport and communications, need no stressing.
However, it is worth remembering that even at the present time, in this year of 1960,
only sixteen per cent of the world’s surface is mapped at a scale of 1/50,000. That is a
scale which, I believe, is generally regarded as quite an essential minimum or maximum,
whichever you call it, for the most elementary planning service.
However, the introduction of photogrammetry as a tool of the surveyor has
enormously increased the speed with which surveys at almost all scales can be com
pleted. At a time when the world is becoming more and more conscious of its respon
sibility towards those under-developed areas, where the standard of living is in some
cases little above starvation level, the importance of photogrammetry as an aid to the
development of such areas cannot be exaggerated.
Photogrammetry is, however, also playing an increasing part in many other
fields: in the conservation of forests; in geology, where it provides the topographical
base, the maps required by the geologist, and by the forester and soil surveyor for
recording their field observations. Furthermore, engineering projects of almost every
