摘要
在山区高程控制测量中,采用GPS测量高程配合全站仪测量三角高程导线的方法代替几何水准测量的方法,得出各测站点的高程。工程实例分析表明:该方法测量精度高而且可靠,完全能满足山区高程控制测量的要求,大大提高了工作效率。
In the altitudecontrol surveying of mountainous areas, the method of geometric leveling is replaced by the method of GPS altitude control surveying and trigonometric leveling with total station instrument, through which we can get elevation of every test site. Engineering case analysis shows that the method is very accurate and credible, which can entirely meet the requirements of the ahitudecontrol surveying in mountainous areas and efficiency is improved greatly .
