高分二号卫星获取的可可西里羌塘自然保护区西侧光学遥感影像

封面图像为高分辨率多传感器细粒度分类标准数据集的数据，呈现的是高分二号卫星于2024年5月21日在青海省可可西里羌塘自然保护区西侧获取的遥感光学影像。图像生动展现了羌塘自然保护区的生态面貌，山脉地形高亢起伏，纹理细节清晰可见，图像中白色部分为高原上少数海拔超过6000 m的积雪山峰。中国科学院空天信息创新研究院赛博智能团队依托高分系列遥感卫星，构建了高分辨率多传感器细粒度分类标准数据集—“空天·四象”，并面向全球开放共享。旨在推动遥感智能解译技术向多模态联合与细粒度识别方向发展，支撑了首个百亿级遥感跨模态基础模型“空天·灵眸”的构建，并连续7年支持国际高分大赛、GRSS DFC等遥感智能赛事开展，显著提升了国产卫星数据成果的全球影响力。

Remote sensing image of the western side of Kekexili Qiangtang Nature Reserve obtained by GF-2 satellite

 The cover image is from the high-resolution multi-sensor fine-grained dataset, presenting remote sensing images captured by the GF-2 satellite on May 21, 2024, on the west side of the Qiangtang Nature Reserve in Kekexili, Qinghai Province. The image vividly depicts the ecological landscape of the Qiangtang Nature Reserve, with high and undulating mountain terrain and clear texture details. The white part of the image is a few snow capped peaks on the plateau with an altitude exceeding 6000 m.The AICyber Team of the Aerospace Information Research Institute，Chinese Academy of Sciences has built a high-resolution multi-sensor fine-grained dataset - AIR-SET , which is open and shared globally. It aims to promote the development of remote sensing intelligent interpretation technology towards multimodal joint and fine-grained recognition. Also, it supports the construction of the remote sensing foundation model, which is called RingMo, and supports the organization of some remote sensing intelligent competitions such as IEEE GRSS DFC, Gaofen Challenge, etc., significantly enhancing the global influence of domestic satellite data.
