GPS技术在公路测量中的综合应用

随着交通事业的发展,公路建设工程日益增多,由于线路长、构造物多,以及测量、施工要求质量高、时间紧,传统的测量方法已不能满足新的要求,为此,迫切需要高精度、快速度、低费用、不受地形通视等条件限制、布设灵活的控制测量方法,GPS系统在这方面充分显示了它的优越性,因此在公路建设中得到广泛的应用。基于此,对GPS的特点及其在公路测量中的应用作了说明。

Synthetic Application of GPS Technique to Highway Survey

Along with the development of traffic business,the highway construction engineering increases increasingly.Because of route being long,construction thing being many,and the quality of survey construction requirement being high,the traditional survey method can't has already satisfied the new demands,so the new survey method is of active demand,which it has high precision,quick speed and layout agile,fee lower and not to restrict terrain intervisibility,that is GPS system.It shows well its superiority in this aspect and so gets the broad application in highway construction.This article mainly introduces the characters and the application of GPS.
