GPS-RTK在山区高速公路纵横断面测量中的应用

Application of GPS-RTK in Longitudinal Section Measurement of Mountain Highways

文中以江西某高速公路纵横断面测量为例,利用GPS-RTK技术对该高速公路进行纵横断面的测量,并采用CASS绘图软件和纬地数据转换插件,将纵横断面测量数据,转换为纬地数据。研究结果表明,GPS-RTK技术可以满足高速公路设计的精度需求。

Taking the longitudinal section measurement of a certain expressway in Jiangxi Province as an example, by measuring the longitudinal section using GPS-RTK technology, and using CASS drawing software and latitude data conversion plug-in, the longitudinal section measurement data can be converted into latitude data.The results show that GPS-RTK can meet the precision requirements of highway design.
