摘要
当前,GPS平面控制网已经得到了广泛的运用,但是GPS高程却运用得不够。本文就南京建立高精度似大地水准面,将GPS RTK测量数据,应用似大地水准面解算软件求算高程,代替传统的水准测量,达到了一般工程和大比例尺测图的高程精度要求,提高了工效、降低了生产成本的应用试验进行了介绍。
Now GPS plane network is wide applied, but GPS height is used little. In this paper, some problems are introduced such as the building of high precise quasi-geoid of Nanjing city, used to compute height with GPS RTK data, meeting the requirement of engineering and large scale mapping. The method advances work efficiency and reduces cost of production.
