Time series of Inland Surface Water Dataset in China (ISWDC)

The Inland Surface Water Dataset in China (ISWDC) maps the water body larger than 0.0625 km² in the terrestrial land of China for the period 2000–2016, in 8-day temporal and 250 m spatial resolution. It is closely correlated with the national reference data with the determinant coefficients (R²) greater than 0.99 in 2000, 2005, and 2010, and possess very good consistency, very similar change dynamics, and similar spatial patterns in different regions with the GSW dataset. The ISWDC data set can be used for studies on the inter-annual and seasonal variation of the surface water systems. It can also be used as reference data for other surface water data set verification and as input parameter for regional and global hydro-climatic models.中国内陆地表水数据集（Inland Surface Water Dataset in China, ISWDC）绘制了2000-2016年间中国陆地范围内面积大于0.0625平方千米的水体，其时间分辨率为8天，空间分辨率为250米。该数据集与2000、2005及2010年的国家参考数据高度相关，决定系数（R²）均大于0.99；同时与全球地表水（Global Surface Water, GSW）数据集在不同区域均具备极佳的一致性、高度相似的变化动态与空间分布格局。该数据集可用于地表水系统的年际与季节变化研究，亦可作为其他地表水数据集验证的参考数据，还可作为区域及全球水文气候模型的输入参数。
