Semantic segmentation of river ice image serves as a critical technological foundation for hydrological monitoring and ice flood early warning system. Current publicly available river ice datasets predominantly utilize UAV-captured image and ground-based photographic observations. To address the limitations of spatial coverage in existing datasets, we present NWPU_YRCC_GFICE - a satellite remote sensing dataset constructed from multi-spectral GF-2 satellite images. The dataset innovatively categorizes river ice into six fine-grained classes across freeze-thaw cycles and covers river ice data from Yellow River (Ningxia-Inner Mongolia section) spanning the past 10 years. We further establish a comprehensive deep learning benchmark, which evaluates 33 state-of-the-art segmentation models and two improved segmentation models based on YOLO and Segformer architecture, separately. Experiments are conducted on the NWPU_YRCC_GFICE dataset and three public river ice datasets (NWPU_YRCC_EX, NWPU_YRCC2, and Alberta river ice segmentation dataset). The proposed models exhibit excellent performance, surpassing the state-of-the-art methods. The presented NWPU_YRCC_GFICE dataset and benchmark enriches the river ice dataset and favors in promoting fine-grained river ice segmentation research from satellite view.
