摘要
介绍了GPS高程转换的多项式曲线拟合模型在矿区变形监测观测线中的应用,编制了相应的高程转换程序并以实例加以验证,将拟合高程和水准测量高程进行比较,得出了在矿区一定范围内用GPS测量代替四等水准测量是可行的,从而大大地节省了人力、物力、财力,提高了工作效率。
It introduces the polynomial curve fitting model of GPS height transformation's application in mining deformation monitoring observation line,organizes the corresponding program of the height transformation and uses the example to verify,compares the fitting height with leveling height and obtains that GPS survey can replace the fourth leveling within a certain range.It greatly save manpower,material resources,financial resources and improve work efficiency.
