Glacial Lakes Detection Dataset
收藏资源简介:
Glacial lake outburst floods (GLOFs) are a major threat to the local communities and important infrastructures in the high mountain regions. Early detection of glacial lakes can prevent these disastrous events. Towards this end, we collected Sentinel 2 true color scenesof High-Mountain Asia (HMA) region using glacial lakes inventory of this region. It covers an area of 2080.12 km2 with nearly 30,121 glacial lakes. After data collection, we retained 1200 cloud free true color images and manually generated their ground truth masks. The train and test sets contain 1000 and 200 images, respectively. The dataset covers lakes with different shapes, sizes and radiometric signatures.
冰湖溃决洪水(Glacial Lake Outburst Floods, GLOFs)是高山区当地社区与重要基础设施面临的主要威胁。对冰湖开展早期探测,可有效防范这类灾难性事件的发生。为此,我们基于该区域的冰湖名录,收集了高山区(High-Mountain Asia, HMA)的Sentinel 2真彩色影像场景。该数据集共涵盖约30121个冰湖,总面积达2080.12平方千米。数据采集完成后,我们筛选保留了1200幅无云真彩色影像,并手动生成了对应的真值掩膜(ground truth masks)。训练集与测试集分别包含1000幅和200幅影像。本数据集覆盖了形态、尺寸与辐射特征各异的冰湖。
