中巴经济走廊冰湖溃决洪水事件数据集（2010-2022年）

本数据集基于历史冰湖灾害资料，基于Landsat、Sentinel、Planet等中高分遥感卫星影像，依据冰湖面积、湖泊沉积，溃口、残留坝体、洪水冲刷与堆积等特征，校验研究区历史冰湖灾害资料的真实性与可靠性。借助遥感技术与平台提取冰湖面积、水量、坝体、影响范围等相关参数，修正或补充事...This dataset is developed based on historical glacial lake disaster records, and utilizes medium-to-high resolution remote sensing satellite imagery from Landsat, Sentinel, Planet and other satellite series. It validates the authenticity and reliability of the historical glacial lake disaster records in the study area by referencing features including glacial lake area, lacustrine sediments, breach points, residual dams, flood scouring and sediment accumulation. Relevant parameters such as glacial lake area, water volume, dam structures and impact scope are extracted via remote sensing technologies and platforms, to revise or supplement the ...
