面向城市级服务的地理实体分类方法与建库分析北大核心CSCD

地理实体数据是实景三维结构化和语义化产品,是实景三维建设标准化产品数据。本文在分析自然资源部技术指导文件及各试点城市地理实体建设相关研究和应用的基础上,基于珠海市试验片区实体建库实践经验,提出了面向城市级服务的地理实体分级分类方法,构建了面向应用服务的地理实体数据集。并以院落、建筑物、道路实体等为例,深入分析其数据组织结构,探索了面向国土空间规划和城市精细治理方面的应用研究。

Analysis of geographic entity classification method and database construction for city services

Geographic entity data is a real 3D structured and semantic product, and it is the standardized product data of real 3D construction. Based on the analysis of the technical guidance documents of the Ministry of Natural Resources and the relevant research and application of the construction of geographical entities in the pilot cities, and based on the practical experience of building the database of entities in the pilot areas of Zhuhai city, this paper proposes a classification method of geographical entities oriented to city level services, and constructs a geographic entity data set oriented to application services. Taking courtyards, buildings, road entities, etc. as examples, the data organization structure is analyzed in depth, and application research oriented to land spatial planning and urban fine governance is explored.
