基于ARX的纵横断面数据与设计线位相对定位的实现

The Realization of Relative Positioning Based on ARX Between Vertical and Cross Section Data and Design Line

基于工程测量中断面数据处理检查所遇到的问题,采用ObjectARX二次开发工具编写了相应的ARX程序,即根据地形图上给定的设计线位,将文本格式的断面数据读入到地形图中,即将各断面高程点展点到地形图上,实现断面点与相应的设计线位相对定位,从而实现每个断面点在地形图中的绝对定位;本程序经在一些道路工程中的应用,收到了较好的效果,为断面数据检查提供一种直观方便的方法。

According to the problems that encountered in the section data processing checks,the program based on the ObjectARX re-development tools has been wrote.According to the design line in the topographic map,section data of the text-format Data is read into the topographic map,Each section elevation point can be viewed in the topographic map,to achieve relative positioning between section points and the corresponding design line,and then achieve absolute positioning for each section point in the topographic map;According to application of the program applied to some Road engineering,it achieves bette results and provides an intuitive and convenient way to check for the section data.
