摘要
通过对沧州地区GPS拟合高程与水准高程的精度对比分析,提出了利用GPS观测值加已知高程点拟合求待定点高程的方法,为GPS技术代替四、五等水准测量方法积累了经验。
The technic of GPS elevation hasn＇t been fully used in surveying.This paper analyses the precision of the GPS planned （拟合） elevation and the trditional level elevation with a lot of data and my experience accumulated in many working years. These analysis provide technical reference for the theory-adding GPS measuring value to the known point to get the elevation of the unknown point.So the technic of GPS may take the place of lower grade leveling.
