* Professionals at Consultancy and higher Management levels, 
* Technicians capable of doing routine assignments in photogrammetry. 
We should therefore evolve a strategy to satisfy the needs of these two main 
groups as well as to strengthen their education needs, including updating 
the competence of these two professional levels with time. 
2. Integrated Planning in Developing Countries 
  
As we are well aware the task of integrated and comprehensive economic 
planning both of human resources as well as Natural Resources is of paramount 
importance to developing countries. Whatever scientific discipline we be- 
long to, our work gathers significance only within the context of a plan, 
a macro economic plan. The fundamental aim of such a plan is the exploration 
and exploitation of our natural and human resources, in such a manner that 
the masses of our people are now and in the future assured of an increasing 
of standard of living and an ever increasing sence of well being and social 
security. 
The basis of such macro economic planning is a definite survey of the natural 
resources of country to develop which the human resources of different 
expertise must be applied. Timely information on the natural resources 
potential, be it for hydro power development, dam and canal construction 
for irrigation; road, run-away, railway or water transport; location of 
towns, factories, urban development and other infra-structural development; 
or property development; property sale or transfer and ownership registra- 
tion; maps on geology, hydrogeology, soils, vegetation and present land 
use, for mineral and ground water exploitation, reforestation, soil ameleo- 
ration and integrated multi-purpose river basin development will have to 
be obtained. These surveys will have to be done basically at three levels, 
at reconnaissance level, semi-detailed and detailed level of survey succes- 
sively eliminating those less potential areas and concentrating on the 
more promising areas as we proceed with increasing the scale of survey. 
It is here that the profession of Photogrammetry /Remote Sensing has to 
play the key role, as these Air Photo Interpretation techniques give the 
necessary information at about one the tenth the time and costs and gives 
information that is both upto date and more accurate and sometimes cannot 
be obtained by other techniques. In fact, many developing countries have 
been able to exploit their natural resources very early because of these 
Aerial/Photo techniques. Sri Lanka is one of them and we consider ourselves 
fortunate as we started using these techniques in the mid fifties and was 
able to map the country at reconnaissance and semi-detailed level and have 
already mapped the major part of our natural resources and prepared Resources 
Survey Reports at these levels of information. The task now before us in 
Sri Lanka is the detailed planning and execution of those projects identi- 
fied as feasible. Now we have proceeded in some instances to detailed sur- 
veys and also to the execution of projects, the largest being the Multi- 
purpose Mahaweli Project with a capital investment of over $ 3,000 million 
(US) in the next five years, building dams and reservoirs that would an- 
nually generate 1600 GWH of energy, with an installed capacity of 535 MW 
and irrigate 200,000 hectares of land for agricultural development and 
settle 200,000 farmer families on the land and benefit through employment 
nearly two million inhabitants both directly and indirectly; while also 
assisting the economic development of the whole country.
