Tamil Nadu Uses AI, Satellites to Detect Water Encroachments

Tamil Nadu has many ponds, lakes, tanks and reservoirs, but some are being occupied or polluted.

Buildings and other structures can block the paths that carry rainwater into lakes.

This can make flooding worse during the rainy season.

It can also leave less water available during summer.

The state government has created two computer systems to watch these water bodies.

The systems use satellite pictures, maps and artificial intelligence.

They can notice changes in water areas and possible construction.

Officials receive alerts so they can check the locations on the ground.

The tools can also help identify sewage and garbage pollution.
