SWIM Water Extent is a 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.2019.05.022 and https://doi.org/10.3390/rs11192330

SWIM Water Extent

Surface Water Inventory and Monitoring (SWIM) Water Extent provides open surface water bodies as identified by an automated processing chain. The water segmentation is derived with sensor-specific pre-trained deep neural networks from high-resolution Sentinel-1 and Sentinel-2 satellite images.
