Aircraft likely to be used for mapping Ganga basins pollution free

News:

• Fitted with powerful cameras, Special Purpose Aircraft may soon fly over the Ganga to survey the river as it courses through five states for a geospatial mapping of its basin to rid it off the pollution and encroachment.
• The survey would be conducted under the ambitious ‘Namami Gange’ programme of the NDA Government which aims at rejuvenating the highly polluted holy river.
• NMCG, which functions under the Union Ministry of Water Resources, River Development and Ganga Rejuvenation, is in discussions with the Survey of India and Indian Space Research Organisation for the purpose.
• The authorities are also contemplating using an advanced laser technique called LIDAR, a visual system that uses reflections from a laser to map the terrain, for the survey.
