Sentinel-2 Wildfire Change Detection (S2-WCD)

Abstract The Sentinel-2 Wildfire Change Detection (S2-WCD) dataset is a specialized collection of multispectral satellite images created to support the development and evaluation of wildfire change detection models. Comprising 41 image pairs with a resolution of 1066 × 1066 pixels, the dataset includes both pre-event and post-event scenes captured across Europe and Oceania. Each image pair is accompanied by pixel-level ground truth masks that identify areas affected by wildfires. The dataset covers 26 significant wildfire events from January 2021 to September 2023 in countries such as Australia, France, Greece, Italy, Portugal, and Spain, ensuring diverse geographical representation. By providing high-quality, accurately labeled data, S2-WCD facilitates the training of deep learning models, improving the accuracy and reliability of wildfire damage assessment and aiding effective disaster management efforts.

摘要：哨兵二号野火变化检测（Sentinel-2 Wildfire Change Detection, S2-WCD）数据集是专为支持野火变化检测模型开发与评估而构建的专用多光谱卫星影像集。该数据集包含41组图像对，分辨率为1066×1066像素，涵盖欧洲与大洋洲地区采集的灾前、灾后场景。每一组图像对均配有像素级地面真值掩膜，用于标记受野火影响的区域。数据集覆盖2021年1月至2023年9月间发生的26起重大野火事件，涉及澳大利亚、法国、希腊、意大利、葡萄牙及西班牙等国家，具备丰富的地理多样性。凭借高质量、标注精准的数据，S2-WCD可助力深度学习模型的训练，提升野火损毁评估的准确性与可靠性，为高效开展灾害管理工作提供支撑。
