Pioneering 3D Mapping of the Ganga River Corridor

The National Mission for Clean Ganga, under the Ministry of Jal Shakti's Namami Gange programme, has embarked on a groundbreaking aerial LiDAR survey to develop a '3D digital twin' of the Ganga river corridor. This ambitious project will cover the stretch of the river from Ballia in Uttar Pradesh to Farakka in West Bengal, encompassing four states.

With the use of cutting-edge geospatial technologies such as manned aircraft, drones, photogrammetry, and geotagged videography, the initiative aims to identify and digitally document critical data including drainage outfalls, confluence points, and floodplains along the river.

This data will not only provide a precise mapping of drains and confluences but also help in pinpointing pollution hotspots and refining wastewater interception planning. It represents a foundational shift towards data-driven river management, enabling authorities to better prepare for monsoons and design riverfront infrastructure that operates in harmony with the river.
