摘要
公路线形是公路路线设计、建设过程中的一项重要指标,是公路改扩建过程中重要的原始资料。运用局域差分GPS对线形资料不完善的低等级公路进行线形恢复来获取线形资料是公路改扩建工程与先进技术的结合,说明了改扩建中运用局域差分GPS技术恢复公路线形的方法以及提高其精度和可靠性需要采取的措施。
This paper illustrated the method of using local area differential GPS technology to recover the highway alignment in the reconstruction, and it also put forward the measures need to be taken for improving its accuracy and reliability.
