tioned several times in this address, photogram- 
metry is basic to all earth-related developments. 
Many of these developments are of enormous 
economic consequence. The capital expenditures 
and the benefits that can be eventually obtained 
from these projects are very large compared to 
the cost of producing the basic maps. Yet noth- 
ing can be done before the basic earth-related 
exploratory and other data has been collected 
and the basic maps produced. Therefore, very 
often, even a slight reduction in the time requir- 
ed to produce all this data will generate benefits 
that are many times greater than the entire cost 
of the mapping projects. 
Furtherhore, what is said here means that when 
you attend this Congress, see the exhibits, enjoy 
the sessions, and take part in the discussions, 
you should keep your attention well focused to 
deeper meanings, and to long-term effects. Keep 
in mind, that in the future there will be an inte- 
grated system and there will be great responsi- 
bilities. Whatever is said at invited and presented 
papers, discussed at sessions, and seen in the 
exhibits, should be subjected to our own ”tech- 
nology assessment”, and evaluated against our 
wider responsibilities. 
But more than that, perhaps much more than 
that, let us all dedicate ourselves to a concerted 
effort towards meeting the challenges and meet- 
ing the responsibilities that we have toward find- 
ing solutions to the problems of our times. We 
should be encouraged by the enormous advances 
that have been made in science and technology 
within our own field, such as the data collection 
by using various sensors, both air-borne and 
satellite-borne, and in the processes which are 
largely based on the power of computers. We 
should also be encouraged by the vast experience 
that exists within our society. Many of the prob- 
lems will be of the organizational nature and the 
cooperation and experience that exists within 
the ISP Commissions have unique powers to 
contribute towards agreements that will help us 
to better meet and better solve the organizational 
problems that are involved in the great challenges 
that we are facing. 
Let us also approach the coming Congress days 
and weeks with an objective of making this Con- 
  
Delegates gathering for the General Assembly. 
40 
gress a success not only as an exciting and 
pleasure event, but also as a historically significant 
event. Let us produce results that will be remem- 
bered in the years to come as breakthroughs 
towards making the contributions of photogram- 
metry recognized as keystones of human pro- 
gress.

Speaker.
