今年9月，我市新一批优化营商环境创新应用场景发布，市规划和自然资源局浦口分局申报的《低 空新质生产力构建营商环境新范式》案例入选。该局探索低空经济技术和实景三维建设深度融合，首次 实现"三维规划核实""不动产远程查验"等创新应用场景，为项目快速落地注入强劲动力。 浦口区海科新寓安置房建设已近尾声，在规划核实阶段，传统现场核查在面对规模大、楼栋多、楼 层高的项目时，面临着效率低、难度高、信息获取不全面等挑战。 市规划和自然资源局浦口分局相关负责人介绍，借助"一网统飞"平台，工作人员可以提前进行无人 机航线规划，并在飞行过程中实时监控现场作业情况，提出业务需求。完成飞行测绘后，再生成实景三 维数据。精细化的实景三维模型可全方位、无死角地真实呈现项目竣工现状，让核实与审批更高效。 "相比过去，我们需要准备的纸质材料减少了，现场核实的工作量也大大减少。"代建单位南京中交 江北城市开发有限公司报件负责人表示，规划核实程序的创新，为企业完成竣工验收争取了时间，让企 业感受到政府部门的服务效率和良好的营商环境。 "这么快就完成查验了？"近日，浦口区某地产项目提出在建工程抵押登记申请后，等来的不是查验 人员，而是可以抵押登记 ...

Core Insights - The Ministry of Natural Resources and the National Data Bureau announced the selection results for the 2025 innovative application cases of real-scene 3D data, with two cases from Shaanxi Province successfully included [1][2] Group 1: Real-Scene 3D Data Applications - The "Real-Scene 3D Empowering Comprehensive Management of Silted Dams in Shaanxi Province" utilizes high-precision digital elevation models and sub-meter resolution imagery as the foundation for 3D geographic scenes, enabling comprehensive lifecycle management of silted dams [1] - The project has played a significant role in the management of 9,374 medium and large silted dams across the province, providing essential data support and platform capabilities for "one dam, one policy" management [1] Group 2: Ecological Protection and High-Quality Development - The "Real-Scene 3D Supporting Ecological Protection and High-Quality Development in the Yellow River Basin of Shaanxi Province" integrates various technologies such as satellite remote sensing, drone surveying, 3D laser scanning, and multi-beam underwater measurement to create a multi-level, multi-scale real-scene 3D data foundation [2] - This initiative has established an integrated regulatory system covering the entire network from provincial to local levels, facilitating scenario-based, visual, and process-oriented services for governance, protection management, and decision-making in the Yellow River Basin [2] Group 3: Future Directions - The Shaanxi Provincial Surveying and Mapping Geographic Information Bureau plans to continue developing real-scene 3D technology, guiding local practices, and expanding applications in farmland protection, spatial planning, cultural heritage protection, and disaster prevention [2]

Core Viewpoint - The integration of new technologies such as surveying and remote sensing is essential for the digital preservation and utilization of cultural heritage, allowing it to thrive in the digital realm while addressing its historical and contextual significance [1][2]. Group 1: Digital Cultural Heritage - Digital cultural heritage refers to the results of digitizing cultural assets, including images, videos, audio, and models, as well as the comprehensive use of technologies like surveying, geography, and artificial intelligence for information retention, processing, management, and application [1]. - The narrow definition of digital cultural heritage focuses on the digitization outcomes, while the broad definition encompasses integrated technologies for data, analysis, services, and application systems [1]. Group 2: Challenges and Solutions - The current 3D models produced in the cultural heritage digitization industry face challenges such as lack of interactivity, dynamic simulation, and effective spatiotemporal empowerment [2]. - The application of real-scene 3D technology is crucial for creating three-dimensional information products that are spatially, physically, and realistically represented, which can enhance the activation and utilization of cultural heritage [2]. Group 3: Practical Applications - The team led by Hou Miaole has collaborated with various institutions to establish multi-layered semantic models for cave heritage, addressing different needs such as archaeology, protection, and utilization [3]. - The practical work includes the digitalization and virtual restoration of the Dazu Rock Carvings, emphasizing the importance of having spatiotemporal semantic information for intelligent virtual restoration [2][3].

Core Points - The Ministry of Natural Resources reports that nearly 300 cities in China have completed the construction of 3D building models, which play a significant role in urban renewal, public service, and empowering the digital economy [1][2] Group 1: 3D Modeling and Technology - China has achieved autonomous control over core technologies such as real-world 3D data collection and spatial identity coding, establishing a 3D technology system characterized by intelligent modeling, integrated management, and knowledge-based applications [2][3] - By the end of 2025, the goal is to establish a preliminary version of "Real Scene 3D China," with nearly 300 cities having produced 3D models of buildings [2][3] Group 2: Applications in Urban Management - The implementation of 3D technology in Fuzhou has empowered over 60 fields, particularly in urban management, allowing for comprehensive perception, dynamic monitoring, and intelligent analysis of urban spatial information [4][5] - Fuzhou's smart management platform utilizes real-time 3D maps to provide detailed insights into urban infrastructure, including streetlights and manholes, enhancing operational efficiency [4][5] Group 3: Water Management and Emergency Response - The integration of 3D models in Fuzhou's water system management allows for real-time monitoring and simulation of water levels, significantly improving flood response times and water quality management [6][7] - The scientific scheduling system for water management has led to an 88% peak flood reduction rate and a 50% decrease in average drainage response time, achieving a 98% compliance rate for river water quality [7]
