SCOPE IN NEXT TEN YEARS 
It would be appropriate to make some observations on high- 
resolution satellite imagery of one and sub-metre resolution. This 
imagery is considered useful for updating the existing maps. In 
India most of the country including cities and towns do not have 
large-scale maps. Original surveys on scale 1:1000 demand an 
accuracy of 20 cm in position and height. In view of this digital 
Photogrammetry is the only solution. 
A modest estimate is made on the basis of large-scale requirements 
for towns, Cadastral surveys, Irrigation projects and precision 
agriculture. 
Field of application Estimated amount 
Cadastral surveys 3.5 Billion USD 
City/Town surveys, Precision 1.12 Billion USD 
Agriculture, Irrigation, Mining, 
Highways, Railways & Forestry 
and outsourcing from other 
countries 
CONCLUSIONS 
Several new factors are influencing the rapid adoption of digital 
Photogrammetry in India. Emergence of desk top systems, Low 
cost of SW, increasing demand for large scale maps, out-sourcing 
from other countries are some of the major factors. Huge domestic 
requirement of large-scale mapping is fuelling the growth of digital 
Photogrammetry in India.
