Product details

Name	High Resolution Layer - Water & Wetness
Acronym	WAW
Description	The product was first produced in 2015 replacing the previous 2012 separate "permanent water" and "wetland" products. The new combined Water and Wetness product is a thematic product showing the occurrence of water and wet surfaces over the period from 2009 to 2015, and 2012 to 2018 respectively. This layer is based on multi-temporal and multi-seasonal optical high-resolution satellite imagery. In addition, this layer is also based on radar information (Sentinel-1 data) with a geometric resolution of 10m on a pan-European basis. A multitude of optical and SAR imagery is used, covering a prolonged time series of 7 years, which aim at capturing the intra-annual dynamics as much as possible within a given area and lead to one image composite per season (each season covered by 3 months) and year during the observation period. They form the basis for the following products: 1) The main Water and Wetness (WAW) product with defined classes of permanent water, temporary water, permanent wetness and temporary wetness. 2) The additional expert product: Water & Wetness Probability Index (WWPI). This product is available at 20m (2015) / 10m (2018) and 100m (both years) spatial resolution.
