自然资源部：近300个城市完成城市三维模型构建

Core Insights - The Ministry of Natural Resources of China has reported that nearly 300 cities at the prefecture level and above have completed 3D building modeling, which plays a significant role in urban renewal, public service, and empowering the digital economy [1][5]. Group 1: Technological Advancements - China has achieved self-controlled core technologies such as real-world 3D data collection and spatial identity coding, establishing a technical system characterized by intelligent modeling production, integrated management, and knowledge-based service applications [3]. - The Deputy Director of the Land Surveying and Mapping Division, Liao Anping, stated that by the end of 2025, China aims to initially establish a "3D China," with data elements already systematized and scaled [5]. Group 2: Applications and Future Plans - The 3D reality technology utilizes modern technologies like remote sensing, big data, cloud computing, and intelligent perception to create nearly identical 3D models of real-world scenes, forming a nationwide "one network" for sharing and applying 3D data [7]. - Future plans include leveraging advancements in artificial intelligence, large models, and spatiotemporal computing to further expand the application scenarios of 3D reality technology across various industries [7].
