本数据集是2017—2021年格陵兰冰面水系产品，反映了格陵兰冰面水系的时空变化特征，空间分辨率为10 m，时间分辨率为逐年。本数据集为整数型栅格数据，栅格值1代表冰面水系，栅格值0代表非冰面水系。数据集存储格式为GeoTIFF格式，总数据量为3272.9 MB。本数据集基于Sentinel-2卫星遥感影像与多空间尺度遥感信息提取方法生产。与人工解译结果对比验证表明本数据集总体制图精度优于85%。本数据集反映了中高分辨率卫星遥感影像在格陵兰冰面水文研究中的应用潜力，提升了对冰面融水输送与存储等关键水文过程的理解。This dataset is a supraglacial drainage network product of Greenland spanning 2017 to 2021, which reflects the spatio-temporal variation characteristics of supraglacial drainage networks over Greenland. It has a spatial resolution of 10 m and an annual temporal resolution. This dataset is stored as integer raster data, where a raster value of 1 represents supraglacial drainage networks, and a value of 0 represents non-supraglacial drainage areas. The dataset is stored in GeoTIFF format, with a total data volume of 3272.9 MB. This dataset was produced using Sentinel-2 satellite remote sensing imagery and multi-spatial-scale remote sensing information extraction methods. Validation against manual interpretation results shows that the overall mapping accuracy of this dataset exceeds 85%. This dataset demonstrates the application potential of medium-to-high resolution satellite remote sensing imagery in supraglacial hydrological research over Greenland, and enhances the understanding of key hydrological processes such as supraglacial meltwater transport and storage.
