摘　　要：针对采用基础地理信息要素数据进行基础地理实体转换生产中存在数据源格式多样、转换工作量大、语义化困难、地理实体三维信息缺失的问题,实现基础地理信息要素数据快速实体化转换及应用,本文设计了一套转换生产流程,应用ETL技术进行数据转换,应用知识图谱和地理信息系统(GIS)空间运算进行实体关系语义化,应用多源高程数据采集基础地理实体三维信息,最终实现快速转换生产基础地理实体数据的应用场景。本方案经生产验证,生产流程和技术可行,满足生产精度要求,且实体化速度快,可应用于多种应用场景。In the cnversion production of fundamental geo-entity data using the fundamental geographic information elements are confronted with various formats,large amount of data,difficult semantic translation,lack of 3D information and so on.A set of production process is designed to realize the rapid materalization production and application of fundamental geographic information elements in this paper.Through the application of ETL technology for data conversion,knowledge graph and geographic information system(GIS)spatial operation for semantic processing of entity relationship,multi-source elevation data for acquisition of fundamental geo-entity 3D information,it has achieved the rapid convert production and application of fundamental geo-entity data.The production process and technology have been proved to be feasible which meet the requirements of production accuracy and obtain fundamental geo-entity data more efficient,and can be applied to a variety of using scenarios.
