The combined Water and Wetness product is a thematic product showing the occurrence of water and wet surfaces over the period from 2009 to 2015. This layer is based on multi-temporal and multi-seasonal optical high-resolution Landsat data, image coverages (HR IMAGE2009, HR IMAGE2012 and HR IMAGE2015 from the ESA DataWare House, DWH), the Copernicus space and contributing Missions (SPOT, IRS), whereas HR IMAGE2015 serves as geometric reference for all satellite data. In addition, this layer is also based on radar information (Sentinel-1 data) with a geometric resolution of 10m on a pan-European basis. Hence, a multitude of optical and SAR imagery is ingested over a prolonged time series of 7 years. The main Water and Wetness (WAW) product with defined classes of (1) permanent water, (2) temporary water, (3) permanent wetness and (4) temporary wetness.
