| 摘 要： | 当前国家大力推动数字化发展，推进数字经济、数字社会、数字政府建设，驱动生产、生活和治理方式的全面深入变革，对基础测绘产品与服务提出了新的更高要求。针对这一重大需求，自然资源部提出实景三维中国建设，研制能客观真实地反映人类生产、生活和生态空间的实景三维信息产品，构建能与现实三维空间实时互联互通的数字三维空间，为数字中国提供新一代的三维时空信息框架，提供高质量时空信息产品与高水平时空信息服务。这既是今后一个时期国家和地方基础测绘的重大任务，也是一项涉及因素复杂、技术难度极大的科技工程。要切实做好这项重要工作，应深化科学认知，厘清技术逻辑，明确基本定位，做好顶层设计。分析了实景三维中国建设的发展背景，讨论了其基本定位和总体技术逻辑，提出了主要的技术实现路径。

| Abstract: | Digital development has been vigorously promoted in China to drive a comprehensive and in-depth change in production, life and governance through the construction of digital economy, digital society and digital government. It has put forward new and higher requirements for basic surveying and mapping products and services. Recently, the Ministry of Natural Resources of the People's Republic of China issued a notice to promote the construction of 3D realistic geospatial scene of China, aiming to develop new 3D geo-spatial information products which can describe and represent the real 3D spaces of industrial production, living environment and ecological development. The construction of such 3D realistic geospatial scene of China will lead to a 3D digital space which can be well connected with the real geo-spatial space through real-time inter-connection, and will provide a new generation of spatiotemporal information framework for the development of digital China. It is not only a major task for national and local basic surveying and mapping agencies in the next few decades, but also a challenging scientific and technological initiative where several complex factors and technical problems remain to be solved. This paper analyzes the background and problems, discusses the development directions and general technical logic, and conductes the major technological path. |
