National Mission for Clean Ganga (NMCG) has partnered with board Survey of India, to facilitate the Ganga rejuvenation task under Namami Gange programme by using Geographic Information System (GIS) technology. Through the project, NMCG aims to strengthen planning and implementation at national, state and local levels.
The project includes use of Digital Elevation Model (DEM) technology which ensures accurate data collection which is important aspect for river basin management planning. DEM technology enables identification of entire topography of area. It supports decision-making process by easily making available data for policy makers. Critical hotspots are also easily identified through this technology.
Significance of GIS technology for Namami Gange programme
It will also ensure decentralisation. The data collected and subsequent actions can easily be shared with local public through geo portals and mobile apps. It will also enable people to send their feedback up to national level thereby providing interactive and transparent platform. It will map all types of other institutions from the source outlet to the public drainage network for effective discharge management. The high resolution GIS enabled data will also help in regulating proposed protected and regulatory zones along banks of river.
