Entire stretch of the Ganga to be mapped using GIS technology 

The Survey of India will soon embark on a massive exercise to map the entire stretch of the Ganga using Geographic Information System (GIS) technology. The resultant high-resolution maps will help authorities monitor activities around the river better. Pollution hotspots and effluent discharge outlets can thus be monitored along the river for about 10 kilometres on either side. The entire process, from mapping to final submission, is expected to take around 15 months.
