摘要:

实景三维中国建设是落实数字中国建设战略、推进国土空间治理现代化、加快测绘地理信息转型升级的一项重要举措,既是今后数十年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。本文介绍了实景三维中国建设的基本思路,从4D产品到实景三维、从数据供给到时空赋能、从数字化到数智化;提出了实景三维中国总体技术架构,包括由地理实体、地理场景、地理实景等组成的产品体系,以提供时空连接、时空计算、时空智能服务为目标的服务赋能体系,以数智化生产、实体化管理、知识化服务为重点的数智技术体系;继而讨论了实景三维中国的主体技术,包括实体化建模、立体化重构、真实化描述和知识化服务等;最后从推动实景三维中国与“五位一体”总体布局深度融合的角度,探讨了实景三维赋能数字经济、数字治理、数字生活、数字文化、数字生态文明等5个应用场景。为切实做好实景三维中国建设与应用,今后还应加强战略谋划,推动科技创新,促进跨界融合。

Abstract:

China has launched recently its national 3D mapping program to build 3D realistic geospatial landscape model (3DRGLM), and has been considered as an important step towards establishing Digital China and transforming our geospatial industry. It is a huge spatio-temporal information engineering with many complex technical and management factors, and is becoming a challenging task for governmental agencies and academy societies. The paper has introduced the motivation and fundamental concepts of the 3DRGLM, i.e., moving from traditional 2~2.5D cartographic products to 3D realistic geospatial landscape products, from simple data supply to spatio-temporal empowerment, from digital to intelligentized mapping. The overall architecture of national 3DRGLM was then proposed and it has a number of key components, such as the data product system for generating geospatial entities, geospatial scenes and realistic geospatial scenes, the service system designed to support spatio-temporal connection, computing, and intelligence, as well as its digital-intelligentized hybrid technological support system. The 3DRGLM has some special key technological issues, including geospatial entity modeling, stereo reconstruction of muti-dimensional real space, realistic description and geospatial temporal knowledge service. Finally, this paper discussed five typical application scenarios of 3DRGLM, including application of 3DRGLM in digital economy, digital governance, digital living, digital culture, and digital ecological civilization. In order to achieve a successful establishment and an in-depth application of national 3DRGLM, it is necessary to carry out strategic planning, enhance scientific and technological innovation and promote cross-border and multi-disciplinary collaboration.
