摘　　要：针对天地图融合矢量数据和母库矢量数据异构和同步问题,该文选择安徽省为实验区域,从生产流程约束和工程技术控制双重角度,提出了天地图融合矢量数据与母库矢量数据双向增量自动同步更新问题的解决方法,主要内容为融合方案配置与实现、增量变化检测模型和要素全生命周期管理3个关键环节的处理流程和方法。经过安徽省的数据检验,该流程和方法初步实现了单要素在全生命周期范围内的可追溯管理,基本解决了融合矢量数据和母库矢量数据双向增量自动同步问题,满足天地图融合矢量数据和母库矢量数据相互转换的要求,为天地图数据同源异构处理任务提供一种灵活的可选方案。To solve heterogeneous and synchronous update issues of fusion vector data and base vector data of map world,this paper chooses Anhui Province as the research area,starting from the dual perspectives of management mechanism and technology control,propose a solution to solve two-way automatic synchronization between fusion vector data and base vector data of map world,including configuration and implementation of the fusion scheme,Incremental change detection model and the whole life cycle management of the features.After the data of Anhui Province are verified,the method of this article preliminarily implements the traceability management of each feature within the full life cycle,it designed to solve the problem of two-way automatic synchronization problem between the fusion vector data and the base vector data of map world,satisfies the requirement of the data conversion between the data of the fusion vector data and the base vector data of map world,and provides a flexible alternative scheme for homologous and isomerism vector data processing tasks of map world data.
