GPS高程测量在水利测绘工程中的运用

Application of GPS Elevation Measurement in Water Conservancy Surveying and Mapping Engineering

近些年来我国水利工程项目规模日益扩大,科学技术的发展给水利测绘工程的改革带来了巨大动力。GPS这一全球定位系统能够准确地接收地球上人造卫星的信号,并发射出电波,准确测量目标地点的实际数值,有效解决传统测量效率低、精度低的弊端,体现出测量工作的准确性和高效性。本文将介绍GPS高程测量在水利测绘工程中的实际应用,并针对当前GPS高程测量存在的误差进行分析,就测量方面提出有效措施以增进GPS高程测量的效率和水准。

In recent years,the scale of water conservancy engineering projects in China has been expanding,and the development of science and technology has brought great impetus to the reform of water conservancy surveying and mapping engineering.GPS is a global positioning system that can accurately receive the signal of artificial satellites on the earth,and emit radio waves to accurately measure the actual value of the target location,which effectively solves the drawbacks of low efficiency and low accuracy of traditional measurement,and reflects the accuracy and efficiency of measurement work.This paper will introduce the practical application of GPS elevation measurement in water conservancy surveying and mapping engineering,analyze the errors of current GPS elevation measurement,and propose effective measures to improve the efficiency and level of GPS elevation measurement.
