HR-VSGeo Series Dataset

Dataset Summary

The HR-VSGeo Series dataset contains high-resolution Synthetic Aperture Radar (SAR) imagery, suitable for tasks such as object detection, semantic segmentation, and image classification. The data is collected from Google Earth and the Gaofen-3 satellite. Annotation work was carried out by the EOC (Elites of CUMT) Lab at China University of Mining and Technology and other collaborators.
