    强降雨诱发群发性滑坡的影像解译及标注数据集

    Remote Sensing Image Interpretation and a Labeled Dataset for Rainfall-Induced Clustered Landslides

    • 摘要: 强降雨常引发空间密集的群发性滑坡,严重威胁生命与基础设施安全,其快速识别对灾害响应与风险评估至关重要。尽管深度学习在遥感滑坡检测中表现突出,但针对强降雨诱发群发性滑坡的高质量标注数据仍然匮乏,制约了模型性能提升与泛化能力验证。为此,本研究构建了一个基于高分辨率遥感影像的降雨诱发群发性滑坡标注数据集。该数据集选取2024年发生在中国中东部的三次强降雨诱发的典型群发性滑坡事件为研究对象,制定统一的滑坡解译规则,基于3m分辨率的PlanetScope卫星遥感影像开展滑坡识别与人工解译,并对解译结果进行裁剪与筛选。最终形成一个包含3190幅512×512像素大小的降雨诱发群发性滑坡样本及其标注数据集,每幅影像平均包含约19处滑坡。数据集包含三部分文件:(1)基于PlanetScope遥感影像裁剪的滑坡灾后影像文件;(2)人工解译生成的滑坡标签文件;(3)用于深度学习模型训练与验证的掩膜文件。在部分典型区域对滑坡解译结果进行了验证,通过与无人机航摄影像解译结果(336处滑坡)进行对比,本研究识别出365处滑坡,其中误报45处、漏报16处,误报主要集中于人工边坡、裸露岩体和冲沟,整体精度较高。该数据集的构建为强降雨诱发群发性滑坡的智能识别、灾害评估与模型泛化研究提供了重要的数据支撑。

       

      Abstract: Intense rainfall commonly triggers spatially clustered landslides, posing serious threats to lives and infrastructure. Rapid and accurate identification of these events is critical for emergency response and risk assessment. Although deep learning has achieved strong performance in remote-sensing-based landslide detection, high-quality annotated datasets tailored to rainfall-induced clustered landslides remain limited, constraining model improvement and generalization assessment. This study constructs a high-resolution remote-sensing labeled dataset for rainfall-induced clustered landslides. The dataset covers three representative clustered landslide events triggered by intense rainfall in central and eastern China in 2024. A unified interpretation protocol was established, and landslides were manually interpreted from 3 m-resolution PlanetScope imagery. The interpretation results were cropped and screened to produce 3,190 image patches of 512 x 512 pixels, each containing an average of approximately 19 landslides. The dataset includes post-event image patches cropped from PlanetScope imagery, manually interpreted landslide label files, and corresponding mask files for deep-learning model training and validation. Validation in representative areas was performed by comparison with UAV-based interpretation results (336 landslides). In the corresponding areas, 365 landslides were identified, including 45 false positives and 16 missed detections. False positives were mainly associated with artificial slopes, exposed bedrock, and gullies, indicating overall high annotation accuracy. The dataset provides an important data foundation for intelligent identification, hazard assessment, and generalization studies of rainfall-induced clustered landslides.
