3D maps on anvil for six cities

- Survey of India wants to execute Munda plan for Ranchi, Dhanbad

A Union government entity made a strong pitch in Ranchi on Tuesday to carry out 3D mapping of the state capital and five other Jharkhand cities, a move that promises to help planners keep up with the changing needs of an ever-growing urban population.

A team of Survey of India officials, led by surveyor general S.S. Rao, presented the key features of such maps to state planning secretary Avinash Kumar and other officials who are also considering them for Jamshedpur, Dhanbad, Hazaribagh, Bokaro and Dumka.

During his presentation, Rao said 3D mapping — detailed maps that takes into consideration every natural or manmade detail of a particular area — would equip the state with data for planning various development works.

These maps, he added, would be particularly helpful for departments like IT, revenue, road construction, transport, urban development and planning, in addition to civic bodies like Ranchi Municipal Corporation.

“3-D mapping of important cities of Jharkhand, including the state capital, had been planned by former chief minister Arjun Munda. Survey of India has shown interest in the job,” Kumar told newspersons after Rao’s presentation at Nepal House.

“We will take a decision on who will do the job for us soon,” he added.

GIS or 3D mapping takes into account every detail of a chosen area enabling town planners to decide on specific projects, be it residential or industrial, that are best suited for various localities. The maps record natural resources, cultural resources, streams, roads, streets and houses.

“The mapping not only suggests land-use patterns, but also earmarks areas to be set aside for civic amenities like sewerage and drainage systems. It also marks out areas for green zones and open spaces,” said an official of Survey of India.

All the six cities for which 3D mapping was being considered were fast growing. Thus, the maps can be expected to help the cities use land resources optimally. “These cities can be developed properly as the map would help developers visualise it in its entirety,” he added.

The state planning and development department, which is handling the project, had invited expressions of interest from prospective agencies, government or private, with experience of at least five years in geographic information system (GIS), 3D mapping, urban planning and other related fields.

Officials declined to reveal how many agencies had shown interest for the job.

Among the other Survey of India officials who were present during Tuesday’s meeting were additional surveyor general (Dehradun) Major General R.C. Padhi, additional surveyor general (eastern zone) Major General M. Mohan and additional surveyor general of Jharkhand Geo-Spatial Data Centre Major General B.D. Sharma.
