地理國情監(jiān)測
geographical conditions monitoring
中科院消息，中國科研團隊對外發(fā)布了全球首套2020年全球30米空間分辨率下的地表覆蓋數(shù)據(jù)集。
該數(shù)據(jù)集由中科院空天信息創(chuàng)新研究院研發(fā)，反映了全球陸地區(qū)域(除南極洲)在30米空間分辨率下的地表覆蓋分布狀況。
2020年全球30米地表覆蓋數(shù)據(jù)集可免費下載，將為地表覆蓋研究和應(yīng)用提供數(shù)據(jù)支持。
地表覆蓋分布是氣候變化研究、生態(tài)環(huán)境評估及地理國情監(jiān)測等不可或缺的重要基礎(chǔ)信息。
近年來，隨著衛(wèi)星遙感和計算能力的不斷發(fā)展，全球尺度中高分辨率地表覆蓋產(chǎn)品的應(yīng)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.
