藏东南雅弄冰川末端冰裂隙分布数据集（2022-2023年）

雅弄冰川位于青藏高原东南部岗日嘎布山，是该地区最大的海洋型冰川。受全球气候变暖影响，该区域冰川退缩剧烈。本数据集基于2022年-2023年实地采集的高分辨率无人机正射影像数据和深度学习方法，对雅弄冰川末端表面裂隙进行了提取，继而获取了每条裂隙的走向、长度、宽度和面积等信息。数据集包含...

Yalong Glacier, located in the Gangrigabu Mountains, southeastern Tibetan Plateau, is the largest temperate maritime glacier in this region. Affected by global climate warming, glaciers in this area have undergone drastic retreat. This dataset is developed based on high-resolution unmanned aerial vehicle (UAV) orthophoto data collected in situ from 2022 to 2023 and deep learning methods. Surface crevasses at the terminus of Yalong Glacier were extracted, and information such as the strike, length, width and area of each crevasse was subsequently obtained. The dataset contains...
