摘要
为缩短规划道路数据的更新周期,提高数据质量,实现数据共享,设计开发了北京市规划道路数据管理系统。研究了规划道路中线条件编号表的设计以及规划道路中线点属性表中曲线标识、曲线位置、非正常曲线标识设置情况;实现了曲线元素计算、派生红线图形编辑和规划道路中线图形输出。系统通过了专家鉴定,并被北京市测绘设计研究院等多家单位使用,实际应用证明,本系统设计合理,达到了预期目的,产生了良好的社会经济效益。
With the purpose of shortening planning road updating period and prompting data quality so as to realize data sharing, the authors designed and developed the planning road data management system in Beijing, studied the design of centedines of planning road condition coding table and curve identifier, curve position identifier, and normal curve identifier in point attribute table of planning road, realized the functions of curve element calculation, and derived redline graph editing and graph output on planning road centerlines. Having been approved by the experts, the system is used in Beijing Institute of Surveying and Mapping. It is proved that the system is well designed and can realize the expected aim and produce better social and economical efficiency.
