地理国情监测
geographical conditions monitoring
中科院消息，中国科研团队对外发布了全球首套2020年全球30米空间分辨率下的地表覆盖数据集。
该数据集由中科院空天信息创新研究院研发，反映了全球陆地区域(除南极洲)在30米空间分辨率下的地表覆盖分布状况。
2020年全球30米地表覆盖数据集可免费下载，将为地表覆盖研究和应用提供数据支持。
地表覆盖分布是气候变化研究、生态环境评估及地理国情监测等不可或缺的重要基础信息。
近年来，随着卫星遥感和计算能力的不断发展，全球尺度中高分辨率地表覆盖产品的应用需求日益迫切。
Chinese researchers have released an updated global land cover dataset for 2020 with a resolution of 30 meters, according to the Chinese Academy of Sciences (CAS).
Generated by researchers from the Aerospace Information Research Institute under the CAS, the dataset reflects the landscape distribution of global land areas (except Antarctica) at a spatial resolution of 30 meters.
The global land cover dataset for 2020 with a resolution of 30 meters, which can be downloaded for free, will offer data support for land cover research and applications.
Land cover distribution information is important for climate change research, environmental assessment and geographical conditions monitoring.
With the development of satellite remote sensing and computing capabilities, there is a growing demand for high-resolution global land cover data products.
