摘　　要：在加快新型基础测绘体系建设、推进基础地理信息数据库向无尺度基础地理实体数据库转变的过程中,地理实体数据建设成了一个需要深入研究的问题。其中,地理实体模型构建及存储管理是一个重点内容。为了实现这一目标,立足省级新型基础测绘建设,通过试点探索,提出基于图元的地理实体数据模型,依托模型建立研究区地理实体数据,并利用关系图谱实现地理实体数据的表达与可视化。研究成果已在江苏省新型基础测绘体系数据库建设中得到应用。In the process of accelerating the construction of a new basic surveying and mapping system and transitioning from a basic geographic information database to a scale-free basic geo-entity database,the construction of geo-entity data has become a topic that requires in-depth research.Among them,the construction and storage management of geo-entity models are key aspects.In order to achieve this goal,based on the provincial-level construction of a new basic surveying and mapping system,a geo-entity data model based on entities is proposed through pilot exploration.The geo-entity data of the experimental area is established relying on the model,and the relationship graphs are used to express and visualize geo-entity data.The research results have been applied in the construction of the Jiangsu Province's new basic surveying and mapping system.
