Theia Surface Water S2 Instant Watermask

The Theia Sentinel-2 Surface Water - Level-2B dataset provides rasterized water detection data from Sentinel-2 MultiSpectral Instrument, along with appropriate flags.

This dataset is also available at Level-3 with monthly and annual syntheses in the Theia Sentinel-2 Surface Water Monthly Synthesis- Level-3B and Theia Sentinel-2 Surface Water Yearly Synthesis- Level-3B datasets respectively.

The dataset was generated using the SurfWater Processing Chain.

The Theia Sentinel-2 Surface Water - Level-2B dataset is organized into the original Sentinel-2 UTM Tiling Grid provided by Copernicus. Each of these tiles nominally contains data over 100 km x 100 km.
