| 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。

| Abstract: | 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. |
