Surface Water Topography · NASA / CNES

The Surface Water and Ocean Topography satellite maps 75-mile-wide swaths of every lake, river, and ocean simultaneously — the first time scientists can observe how water moves across the entire surface of Earth. For the first time, flood forecasting models can see where the water is going, not just where it has been. A fundamental change in how we manage water for billions of people.
