高速铁路工程数据空间化方法研究
Research on Engineering DataSpacing Method of High￣Speed Railway
摘要
Abstract
Achieving a space￣based high￣speed railway engineering data was necessary for the production and upda￣ting 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 engi￣neering data of Wuhan￣Guangzhou high￣speed railway with some existing images and collected vector data.关键词
