In Survey of India, there is a strength of about 
3000 technical manpower inclusive of all levels 
but exc lud ing about 1500 emp loyed on 
non-photogrammetric jobs like drafting and others. 
A fair number of personnel trained In 
photogrammetry have retired. About 20% of the 
technical manpower trained in photogrammetry is 
available for productive work.

REQUIREMENT OF TRAINED MANPOWER 
Based on the reports published by the Planning 
Commission, Government of India, the requirement 
of trained manpower in the utilisation of Remote 
Sensing technology in different fields like 
Agriculture, Geology, Forestry, Water Resources, 
Urban & Rural Studies, Oceanography, Soil & Land 
Uses works out to two thousand per year in 
236 
India (Planning | Commission, 1988). This 
requirement is mainly for thematic mapping of 
medium and small scales which depend to a great 
extent on photogrammetr ically produced 
topographical maps. Large scale surveys are 
carried out for Urban Development, Irrigation 
Projects, Town Planning, Cadastral records and 
others based on aerial photography. For cadastral 
and urban surveys, the normal scales of 
surveys/maps range from 1:4,000 to 1:8,000. The 
magnitude of cadastral surveys can be guaged from 
the fact that large scale surveys are required for 
about 5,76,000 villages in India covering an area 
of about 160 million hectares. Urban area 
requiring large scale maps is around 53,200 sq.km. 
If these large scale surveys required for various 
planning and development purposes are to be 
completed in a period of 10 years using 
photogrammetric methods, the requirement of 
trained manpower works out to approximately 3,000 
per year. 
The programme of completing topographical surveys 
on 1:25,000 scale covering about 19,700 sheets was 
taken up in late 1970s. By 1990, only 40% of the 
sheets could be completed. This task also needs 
substantial strengthening of photogrammetric 
potential including the training component. 
The capacity of STI for training in Photogrammetry 
at different levels per year is about 120. A few 
universities are also offering Postgraduate 
programmes in Photogrammetry. This number is not 
only small but the knowledge gained in university 
atmosphere lacks practical orientation. Thus, it 
can be seen that there is a very wide gap between 
requirement of trained manpower and the manpower 
being trained at present. 
According to a Departmental Report, the potential 
of Survey of India was found to be one-third the 
survey demands (Government of India Report, 1984). 
With the establishment of two Digital Mapping 
Centres and one Modern Cartographic Centre, with 
emphasis on restructuring training, there is hope 
that this mismatch would improve. 
MODERNISATION 
STI had always been alive to the technological and 
other changes taking place in the field of 
Surveying and Mapping. In view of the emerging 
digital environment, restructuring of STI courses 
has been attempted as a part of  ITC-STI 
Modernisation Project in 1990. The rationale 
behind the idea of restructuring the courses was 
to ‘ntroduce appropriate modifications in the 
curriculam to meet the rising demands in the 
country for correct, uptodate and appropriate 
information needed for resource management. 
Restructuring was also intended to strengthen STI 
to fulfill its aim of educating Survey of India 
personnel in coping with the changing scenario. 
The course curriculam Board  summarised the 
objectives of restructuring as follows: 
- to prepare the trainees to make judgement and 
choices as to equipment, production processes 
and staff development in all disciplines 
contributing to the production of maps and other 
geo- information products.
