摘要
针对公路测量的特点,阐述了利用GPS实施基本测量的原理,介绍了高程拟合在公路测量中的应用情况,经实例验证得出:拟合出的正常高,可以满足公路带状地形大比例测图精度的要求,在地势平坦地区,其精度也达到了Ⅳ等水准测量的精度要求。
In light of the characters of highway surveying,this paper illustrates the principle to implement surveying by GPS,introduces the application condition of height fitting in highway surveying,and gets the normal height proved by practice,which can satisfy the requirement of vast scale mapping accuracy of highway banded topography and achieves the accuracy requirement of Ⅳ grade leveling survey in the district with flat topography.
