摘　　要：生产基础地理实体,构建基础地理实体数据库,是当前新型基础测绘和实景三维中国建设的核心任务。本文围绕基础地理实体数据生产,以EPSE平台为例,结合广州市具体实践,详细介绍了基于已有数据转换和基于地理场景数据生成的二维形式表达基础地理实体数据生产,以及标签单体化、切割单体化、重建单体化等三维形式表达的基础地理实体数据生产,并重点分析存量数据转换生产模式和一体化增量数据生产模式的关系和差异,为其他城市开展基础地理实体数据生产提供借鉴和参考。The production of fundamental geographic entities and the construction of fundamental geographic entity databases are the core tasks of the current new fundamental surveying and mapping and real scene 3D China construction.This paper focuses on the production of fundamental geographic entity data and takes the EPSE platform as an example,combined with the production practice in Guangzhou,this paper introduces in detail the production of fundamental geographic entity data in two-dimensional form based on existing data conversion and geographic scene data generation,as well as the production of fundamental geographic entity data in three-dimensional form such as label,cutting and reconstruction monomer.The relationship and difference between stock data conversion mode and integrated incremental data production mode are analyzed,which can provide reference for other cities to carry out fundamental geographic entity data production.
