SWIM Water Extent - Sentinel-1/2 - Daily

SWIM Water Extent is a global surface water product at 10 m pixel spacing based on Sentinel-1/2 data. The collection contains binary layers indicating open surface water for each Sentinel-1/2 scene. Clouds and cloud shadows are removed using ukis-csmask (see: https://github.com/dlr-eoc/ukis-csmask ) and are represented as NoData. The water extent extraction is based on convolutional neural networks (CNN). For further information, please see the following publications: https://doi.org/10.1016/j.rse.2019.05.0 22 and https://doi.org/10.3390/rs11192330

Statement

The main input datasets are daily Sentinel-2 L2A and Sentinel-1 GRD at 10 m pixel spacing. The Copernicus GLO-30 DEM is included as an auxiliary dataset. For more information please refer to Wieland et. al (2019) (10.1016/j.rse.2019.05.022) and Bereczky et. al (2022) (10.1109/JSTARS.2022.3152127)
