Copernicus High Resolution Water Snow and Ice Monitoring: Water and Ice Cover by Sentinel-2 (WIC S2) 20m

The Sentinel-2 Water and Ice Cover (WIC S2) product is generated in near real-time at European scale, based on optical satellite data from the Sentinel-2 constellation. The product provides the water and ice extent, including snow-covered or snow-free ice on water bodies (rivers and lakes), at a spatial resolution of 20 m x 20 m.
WIC S2 is one of the products of the pan-European High-Resolution Water Snow & Ice portfolio (HR-WSI), which are provided at high spatial resolution from the Sentinel-2 and Sentinel-1 constellations data from September 1, 2016 onwards.
The WIC S2 product is distributed in raster files covering an area of 110 km by 110 km with a pixel size of 20 m by 20 m in UTM/WGS84 projection, which corresponds to the Sentinel-2 input L1C product tile. Each product is composed of separate files corresponding to the different layers of the product, and another metadata file.

哨兵二号（Sentinel-2）水陆冰覆盖（WIC S2）产品基于哨兵二号（Sentinel-2）星座的光学卫星数据，以近实时模式在欧洲全域生成。该产品可提供水陆冰覆盖范围，涵盖河流、湖泊等水体上的积雪覆盖冰体与无积雪冰体，空间分辨率为20米×20米。
WIC S2是泛欧洲高分辨率水陆雪产品组合（High-Resolution Water Snow & Ice portfolio, HR-WSI）旗下产品之一，该产品组合自2016年9月1日起，依托哨兵二号（Sentinel-2）与哨兵一号（Sentinel-1）星座的卫星数据，提供高空间分辨率的相关成果。
WIC S2产品以栅格文件形式分发，单幅文件覆盖110千米×110千米范围，像素尺寸为20米×20米，采用UTM/WGS84投影，与哨兵二号输入的L1C产品分幅保持一致。每份产品由对应产品不同图层的独立文件，以及一份元数据文件共同组成。
