experiment and to enlarge the use of simple photogrammetry
but the number of personnel trained was small« After the
Second World War, the use of radial line methods was
increased but training was imparted to personnel with
special aptitude for air survey* It was soon realised
that the pace of photogrammetric survey had to be incre
ased if all the survey demands for development project
surveys had to be met* The use of stereo-restitution
photogrammetric instruments was introduced in India in
1954, A handful of officers were educated in University
College, London and the International Training Centre for
Aerial Surveys(ITC), the Netherlands* The services of
Mr« Hollan Hagen, a Norwegian photogrammetric expert
were obtained for two years*
During the years 1954 to 1964, additional
photogrammetric instruments were procured but the training
was carried out as required basis, and was mainly for
photogrammetric operators. It was soon realised that the
application of photogrammetry required mastery of complex
techniques and the training need were of higher nature.
This called for more intensive and Well-coordinated
photogrammetric educational programme and international
assistance through the United Nations Development Programme
was sought and obtained*
After a decade of photogrammetric practice in India
a clearer picture of photogrammetric educational requirement
emerged which identified three levels of photogrammetric
instructions— the first at post-graduate or professional
level for executive officers who can plan and execute
photogrammetric tasks independently, take up applied research
and impart Instructions at graduate or post-graduate level,
the second at graduate or technologist level for persons
of supervisory level who should be able to solve technical
problems related to production and guide and supervise
technicians, and the third at the technician level for
persons who can carry out photogrammetric plotting or
photogrammetric extension of control under guidance or
supervision* Dr. A.J* Brandenberger, Chairman, ISP
