Dehradun (Uttarakhand): Amid Unplanned and uncontrolled construction in the name of development driving Joshimath to the brink of sinking, the state Disaster Management department tasked to mitigate the crisis does not have a base map of the subsidence-hit region. The department has now written a letter to the state's Information Technology Development Agency (ITDA) to make a contour map for them to help them devise its future course for the affected region.
The letter written by the Additional Chief Executive Officer of Uttarakhand State Disaster Management Authority, Savin Bansal to Nitika Khandelwal, Director of ITDA on January 24. Nitika Khandelwal said, "the preparation of contour maps is usually done by the Survey of India or the Uttarakhand Space Application Center (USAC). However, we have taken efforts to prepare a contour map using drones."
Professor MPS Bisht, former director of USAC says, "a base map of any area is required during a disaster or any natural calamity. Every geographical information of the area is integrated on this map." While the natural topography makes places like Joshimath vulnerable to land subsidence, the pressure of human activity has exacerbated it, after which Joshimath started facing frequent landslides, he said.
