高速铁路工程数据空间化方法研究

Research on Engineering DataSpacing Method of High-Speed Railway

为了满足地图生产和更新需要,设计了高速铁路缓和曲线和圆曲线的解算坐标系,推导了相应的解算公式,并通过判断车站、桥梁和隧道所属的投影带进行相应的坐标解算,从而实现了高速铁路工程数据的空间化。在此基础上,通过对武广高速铁路工程数据空间化后得到的地理坐标与现有的影像和采集的部分段数据进行对比分析,验证了文中所提高速铁路工程数据空间化方法的可用性和正确性。

Achieving a space-based high-speed railway engineering data was necessary for the production and updating of maps. The coordinate system and formulas for solving the coordinate of ease curve and circular curve in a high-speed railway were designed and derived, and the coordinates of stations, bridges and tunnels were calculated through judging the belonging projection. The availability and correctness of the approved methods and formulas were verified through the experimental analysis comparing the geographic coordinates obtained by spacing the engineering data of Wuhan-Guangzhou high-speed railway with some existing images and collected vector data.
