High Resolution Layers - Water and Wetness

High Resolution Layers (HRL) are raster data with 10m (20m for change layer) and 100m spatial resolution, which are part of the Copernicus Land Monitoring Service. The Water and Wetness product contains 2 data sets: Water and Wetness (WAW) and Water-Wetness-Probability-Index (WWPI). Data is created by semi-automatic procedures over satellite imagery every 3 years.
