公路横断面测量是公路测量的一个重要组成部分,目前的测量方法还仍在使用老办法,外业工作量大,且测绘精度不易保证。为了有效地绘制横断面图,我们在仪器设计、制造与应用方面,采用了一种新方法,并 Highway cross-section measurement is an important part of highway survey, the current measurement methods are still using the old method, the workload of the field, and mapping accuracy is not easy to guarantee. In order to effectively draw the cross-sectional view, we adopted a new method in the design, manufacture and application of instruments, and
