JRC Global Surface Water
Global Surface Water Explorer. 30 m surface water occurrence and change since 1984.
Where and how often water was present on the surface, from every Landsat scene since 1984: occurrence, change, seasonality, recurrence, transitions and maximum extent. Tiles are 10° × 10° and named by their north-west corner.
