Hyderabad: “Advances made in space, technology and remote sensing capabilities have enhanced the utilization of satellite imagery for large scale mapping in the Country, when there were serious apprehensions about this in the Country even few years back”, said Mr. M. Shashidhar Reddy, vice Chairman, National Disaster Management Authority. He was inaugurating the seminar on theme “Issues of Accuracies and Standard of Large Scale Mapping from High Resolution Satellite Imageries”. The programme was jointly organized by the Institution of Engineers (India) AP. State Center and Institution of surveyors, Hyderabad Branch, to observe the National Survey Day.
Mr. Reddy appreciated the initiatives of Survey of India to create National Topographic database on 1:10,000 scale for rural areas, Simultaneously the project would generate 1:2,000 scale maps for 800 cities and 1:10,000 scale map for metros. However, Mr. Reddy observed that in view of the fast trends of urbanization in the Country, urban population in India is projected to be about 1 billion out of total population of 1.6 billion, in the next 30-40 years, which will reverse the present urban-rural ratio.
To deal with rapid urbanization Mr. Reddy called upon all the agencies to focus on taking up mapping, in the next three years, of all 2325 class I,II,III cities, with an existing population of 5000 and above, which cover about 54,000 sq km. This accounts for only 1.65% of the total land area of the Country, which is 3,287,263 sq km.
Mr. Swarna Subba Rao, Surveyor General of India, Dr. V. Jayaraman, Director of the National Remote Sensing Centre, Hyderabad and Dr. P. Nag, Former Surveyor General and Director, NATMO, Kolkata, addressed the delegates during the inaugural session. An exhibition of the latest equipment for survey, mapping and disaster management solutions was also put up. (NSS)
