Scientists in India will soon start mapping the Ganges river, the largest, yet one of the most polluted rivers in the country.
Under the project, headed by the national surveying agency, the Survey of India, 3D maps of the topography of the river and the human settlements around it are prepared using Lidar instruments.
The final map is to be available by the end of the next year.
monitoring of the river cleaning works “The high-resolution map will help us in keeping tabs on sources of pollution and taking quick corrective measures. Such scientific map is necessary for the effective execution and monitoring of the river cleaning works,” Rajeev Ranjan Mishra told The Times of India.
The project is to cost 870 million rupees (US$12.7 million), which is a small fraction of the 200 billion rupees plan, the Namai Gange, that the government has started to save the river.
“Right now, we do not even have a simple topography of the basin,” Vinod Tare of the Indian Institute of Technology in Kanpur, who has been associated with the river rejuvenation projects, told Nature.
