Hephaestus
收藏资源简介:
Hephaestus数据集由国家天文台的天文、空间应用与遥感研究所创建,是首个大规模、手动标注的InSAR数据集,专注于全球火山监测。该数据集包含19,919个单独的Sentinel-1干涉图,分为216,106个InSAR补丁,涵盖44个全球不同火山。数据集的创建过程涉及多学科专家团队,包括地球观测科学家、地质学家、地球物理学家和计算机科学家,共同进行数据标注。Hephaestus数据集的应用领域广泛,旨在解决火山状态分类、地面变形语义分割、InSAR图像质量评估等问题,为地球物理研究和地质灾害缓解提供支持。
The Hephaestus dataset was developed by the Institute of Astronomy, Space Applications and Remote Sensing under the National Astronomical Observatories. It is the first large-scale, manually annotated InSAR dataset focused on global volcanic monitoring. This dataset comprises 19,919 individual Sentinel-1 interferograms, which are split into 216,106 InSAR patches, covering 44 distinct volcanoes across the globe. The creation of the Hephaestus dataset involved a multi-disciplinary expert team consisting of Earth observation scientists, geologists, geophysicists and computer scientists, who jointly carried out data annotation. The Hephaestus dataset has broad applicability, targeting tasks including volcanic state classification, semantic segmentation of ground deformation, and InSAR image quality assessment, providing support for geophysical research and geological disaster mitigation.
