CHENNAI: A three-dimensional map detailing every nook of the city and its sub-surface systems will soon be a reality.

The power supply lines, the telecom network, the water supply and sewerage lines and buildings dotting the cityscape will all be incorporated into the map, officials involved in its preparation said.

The number of service lines criss-crossing the metropolis has grown tremendously as the city. The service agencies — Chennai Corporation, Metrowater, Electricity Board and Bharat Sanchar Nigam Limited — have struggled to keep pace with the swelling demand for utilities and thus planning suffered.

The exercise is part of the Union Government's mission to create digitised maps of Mumbai, Kolkata, Chennai, Ahmedabad, Hyderabad and Bangalore as done for New Delhi.

Field survey

The base map would be derived from aerial photographs to be taken by the Survey of India. A detailed field survey would then bring out the geographical information of each locality. The information on the utility networks would be provided by the different Government departments, the officials said. The map would be on a scale of 1:1000.

The Utility Mapping Division of the National Informatics Centre, the nodal agency for the exercise, will provide logistical support. The Planning Commission has allotted funds for the hardware and software for the map, the server and the connectivity.

Altitude information

NIC officials said that the map would also provide altitude information of each point in the city.

Preparing the base map alone would cost over Rs. 1 crore at the rate of Rs. 60,000 a sq. km., the officials added.
