摘要
对地观测数据作为国家基础性和战略性资源,在国民经济、社会发展和国家安全中发挥着不可或缺的作用。我国正面临从对地观测"数据大国"向"数据强国"转变的历史新机遇,文章阐述了当前对地观测大数据的发展态势,总结了国际对地观测数据开放共享的现状与趋势,分析了我国对地观测数据开放共享的现状及问题,最后对我国对地观测大数据的开放共享给出了3个方面的建议:①加强数据治理体系建设,夯实对地观测数据开放共享的基础;②制度和技术并重,构建良好的数据共享生态系统;③创新对地观测数据共享服务模式,促进学科交叉、知识发现与综合应用。通过加强数据开放共享工作,以期能够释放我国对地观测大数据的潜在价值,充分发挥对地观测大数据的战略性作用,有效提升我国对地观测大数据的国际竞争力。
Earth observation（EO） data, as the basic and strategic resource of a country, plays an important role in national economy, social development, and defense security, and a new era opportunity of the transition from a ＂great country of data＂ to a ＂strong country of data＂ is coming to China. This paper summarizes the existing conditions and recent trends of opening and sharing of EO data from both international and domestic perspectives, and then analyzes the problems and challenges of opening and sharing EO data in China. Finally, three suggestions are proposed to promote the opening and sharing of China＇s EO data, namely,（1） the construction of data governance system needs to be strengthened to consolidate the foundation for opening and sharing EO data;（2） a sustainable data sharing ecosystem needs to be maintained from regulation and technology;（3） the innovative service modes of data sharing should be created to deepen the application of EO data. By strengthening the data opening and sharing, the potential value of China＇s EO big data can be discovered and the strategic role of EO data can be fully motivated. Therefore, the international competitiveness of China＇s big EO data will be effectively enhanced.
