基于地理实体的道路交通空间数据库设计与建设

道路交通是城市最重要的基础设施,但现阶段道路交通空间数据往往重视空间表达,忽略管理特性,针对上述问题,本文提出基于地理实体的道路空间数据库建设思路。通过分析空间特征、研究数据构成,提出了道路交通实体模型,进行了地理实体空间数据库设计,最后阐述了基于地理实体思想的空间数据建库流程,并探讨了边界确定、交叉口归属等问题的解决思路。

Design and Construction of the Road Spatial Database Based on Geographic Entity

The road is the most important infrastructure in the city , but the spatial data of the road always focus on the spatial charac-teristics and ignor the management characteristics .Aiming at the above problems ,this paper proposes the road spatial database con-struction ideas based on the geographical entity .After the analysis of spatial characteristics and the research on the data structure , this paper establishs the geographic entity model , design the spaital database , and discusses the spatial data acquisition process .Besides, this paper also discusses the solution of the boundary determination and the ownership of road intersection .
