摘要
对GPS高程拟合在铁路线路工程测量中的应用进行了探讨,该方法具有毋须通视,经济实用,精度较高,实时效益提高等优点,结合工程实际,研究了高程曲面拟合模型平滑连接法,以满足长大线状工程勘察初期采用GPS高程测量精度的规范要求。
The paper explores the application of GPS height models in engineering survey,indicates the light of sight is not needed by adopting the method,which is economical and practical,with high accuracy and improvement timely efficiency,and researches the smooth connection method of the height curve fitting model,so as to meet the regulation’s demand for adopting GPS height accuracy in the primary period for long and large route projects.
