摘要
地理实体是新型基础测绘产品体系中的核心成果,是推动基础测绘工作转型升级的关键。结合新型基础测绘青岛试点工作,并依据高精地图对道路要素表达的要求,设计了道路高精地理实体的分类与代码,探讨了道路高精地理实体的生产作业流程、道路要素矢量采集方法,按照智能导航对道路要素语义化表达的要求,设计了道路高精地理实体之间的关联规则,结合青岛试点某试验区,介绍并展示了道路高精地理实体生产的主要工作思路和成果,可为其他城市试点工作提供参考。
Geo-entity is the core achievement in the new fundamental surveying and mapping product system and is the key to promote the transformation and upgrading of fundamental surveying and mapping work.Combined with the pilot work of new fundamental surveying and mapping in Qingdao,and on the basis of the high accuracy map requirements for road element expression,this paper designs the classification and code of road high-accuracy geo-entities,discusses the production process and the vector acquisition method of road high-accuracy geo-entities.According to the requirements of road elements of intelligent navigation semantic expression,it designs the rules of association between the road high-accuracy geo-entities.Combined a pilot area in Qingdao,it introduces and shows the main work ideas and achievements of road high-accuracy geo-entity production,providing reference experience for pilot work of other cities.
