丝绸之路沿线重点区域洪扎河流域冰川编目数据集（1990-2020年）

采用波段阈值法和人工修正相结合，基于Landsat历史卫星影像汇编了丝绸之路沿线重点区域洪扎河流域1990~2020年间4个时期（1990s, 2000s, 2010s, 2020s）的大于2km2的冰川编目。数据质量得到了高分辨率图像多次解译结果的验证、缓冲区误差估计方法评价和多个...

Adopting a combined approach of band thresholding and manual correction, we compiled glacier inventories with an area greater than 2 km² for the Hunza River Basin, a key region along the Silk Road, using historical Landsat satellite imagery across four periods (the 1990s, 2000s, 2010s, and 2020s) from 1990 to 2020. The data quality was validated using multiple high-resolution image interpretation results, evaluated via buffer zone error estimation methods, and multiple...
