记者今天（25日）从自然资源部获悉，目前我国已有近300个地级以上城市完成建筑三维模型建模。在 支撑城市更新、服务百姓生活、赋能数字经济等方面发挥了重要作用。 近300个城市 完成城市三维模型构建 自然资源部表示，目前我国已经实现了实景三维实体数据采集、空间身份编码等核心技术的自主可控， 初步构建了以数智化建模生产、实体化集成管理、知识化服务应用为主要特征的实景三维技术体系。 自然资源部国土测绘司副司长廖安平：2025年底左右，我们将初步建成实景三维中国。目前数据要素已 成体系、成规模，已经完成近300个地级以上城市建筑物三维模型生产。 目前，福州新区"智脑"项目已经打造了188平方公里实景三维数据底座，能够总览新区地上地下、室内 室外全立体空间，构建了新区全景、规划蓝图等五大专题应用平台。 实景三维技术，简单来说就是运用遥感、大数据、云计算、智能感知等现代技术，在虚拟的数字世界 中，创建出与现实场景几乎一模一样的三维模型，从而为智慧城市建设、城市精细化管理、应急救援等 各项工作提供三维空间底图。 自然资源部国土测绘司副司长廖安平："十五五"期间，我们将持续推进实景三维数据处理的自动化、智 能化，打通应用服务 ...

Group 1 - The core viewpoint of the news is the significant progress made in the construction of a three-dimensional digital China, driven by the Ministry of Natural Resources through various stages of pilot exploration, localized application, comprehensive deployment, and accelerated empowerment [1][2] - The supply of data elements has been continuously enhanced, with 7.35 million square kilometers of digital elevation model data produced, 7.9 million square kilometers of basic geographic entity data completed, and 21 versions of orthophoto data with sub-meter/2-meter resolution covering the entire land territory of the country [1] - A total of 310 cities at the prefecture level and above have initiated three-dimensional city construction, resulting in approximately 110,000 square kilometers of urban three-dimensional model data produced [1] Group 2 - The technical standards and systems have been increasingly refined, comprising a technical standard system that includes technical outlines, 25 technical documents, and several national and industry standards, covering the entire construction process from design to quality control [2] - The application of three-dimensional digital China is expanding, with over 100 application scenarios across 22 categories, including disaster prevention, smart security, cultural heritage protection, land spatial planning, and online tourism [2] - The Ministry of Natural Resources plans to accelerate construction, focus on application, and build an ecosystem to support the development of high-quality geographic spatial data sets, aiding in natural resource management and land spatial planning [2]
