SURVEY OF INDIA GOES HIGH-TECH IN MAPPING


The Survey of India has gone high-tech introducing Digital camera integrated, Airborne Laser Terrain Mapping Technology. Launched as a pilot project of the Department of Science and Technology, the Airborne Laser Terrain Mapping (ALTM) is being executed in collaboration with a Delhi-based Aerial survey firm with fully integrated systems and equipment. With this the survey of India has become the first to utilise the ALTM system in India and may be the first in the Asia-Pacific region.

Induction of ALTM forms an important part of the large scale modernisation of the Survey of India and will enable it to produce large scale geospatial data bases and meet customer's new requirements. This will also enable Survey of India to play a much bigger role in the creation of National Spatial Data Infrastructure (NSDI).

The Survey of India collected the data during May and now it is under process. From these data it will produce Digital Terrain Model (DTM), Digital Elevation Model (DEM), Orthophoto maps, line maps and fly-throughs.

After signing the agreement with the Delhi firm, the Surveyor General of India said here yesterday that now we have the capability to generate very highly accurate maps in very quick time, specially needed for pre and post disaster management, corridor surveys for infrastructure development such as national highways, railways and inter-linking of rivers. Flood plain mapping is a very crucial area, where this technology can be effectively used. Survey of India will now be offering its services to all the Agencies, including private, requiring large-scale maps for urban and rural planning, disaster management, infrastructure development, revenue records maintenance.
