摘　　要：随着城市建设步伐的加快和基础地理信息应用领域的扩展,国家经济建设和人民群众生活对基础地理信息的需求越来越大,对基础地理信息的现势性和更新频率也提出了更高的要求。因此,对不同精度、不同来源的地理信息数据融合技术进行研究具有十分重要的意义。道路实体是重要的基础地理信息,尤其是铁路、高速、国省道、城市主干道。本文重点围绕道路实体研究数据间的差异性,建立了自动匹配评价指标;并基于FME平台搭建同名匹配、变化检测和增量更新模型,实现了道路实体自动更新和融合,缩短了道路实体更新周期。"十三五"第2轮基础测绘更新项目利用该技术完成了重要道路实体的融合,证明了该技术的可行性和准确性,为新型基础测绘体系的建设提供了技术支撑。With the acceleration of the pace of urban construction and the expansion of the application field of basic geographic information,the national economic construction and people’s life have an increasing demand for basic geographic information,which also puts forward higher requirements for the current situation and update frequency of basic geographic information.Therefore,it is of great significance to study the geographic information data fusion technology with different accuracy and different sources.Road entity is an important basic geographic information,especially railway,expressway,national and provincial road,urban trunk road.This paper focuses on the road entity,studies the differences between data,establishes automatic matching evaluation index,and builds homonymous matching,change detection and incremental updating model based on FME platform,realizes the automatic updating and fusion of road entity,and shortens the updating cycle of road entity Period.The second round of the 13 th five year plan basic surveying and mapping update project uses this technology to complete the integration of important road entities.Through analysis and verification,it proves the feasibility and accuracy of the technology,and provides technical support for the construction of new basic surveying and mapping system.
