One picture of every frontier.

River levels, heat stress, sea state, official alerts and response teams on a single map, with the source and time of every number one click away.

The Trinetra console's Today page: a tile for each live product, a map of India with river stations, heat-risk towns, fishing harbours and response alerts, and a list of the places that need attention and why.
The console home, with live data from today's run. Simulated layers are labelled.

Built for the hour that matters.

See it early

Each river is read against its own 29-year record, so a rise shows up as unusual for the date, days before it becomes a flood.

About Varuna

Respond safely

Recommendations weigh travel time against wind, rain, river flow and heat, so the fastest team is also a safe one to send.

Areas each team can reach in 5, 10 and 20 minutes. Simulated sector on the Ichamati.

About Gati

Every query, view and decision is sealed into a hash-chained ledger that an auditor or a court can verify line by line.

We watch rivers, weather and the sky. Never people.

No profiles, no scores

Trinetra analyses events, places and conditions. It does not profile or score any person, and private names in public records are withheld.

Every number has a source

Each reading shows where it came from and when. Anything simulated is marked as simulated, everywhere it appears.

Every action is on the record

Sensitive work needs a declared purpose and a second approver, and every step lands in a ledger anyone with access can verify.
