基于CORS的河道测量方法——以娄宋沟河道测量为例

Measurement Method of Riverway Based on CORS——Taking Lousong River Survey as An Example

在一定区域内,GPS连续运行参考站系统(CORS)可向用户提供高精度的实时差分定位信息,深化了GPS在测量工程中的应用层次。以淮水北调娄宋沟河道测量项目为平台,应用CORS测量技术,通过内外业一系列工作,完成了河道测量中带状图、纵横断面图的绘制,为项目施工方案提供准确、可靠的测量资料。并进行了大量的测量数据的处理与分析,表明CORS技术足以高效、精确地完成河道中的测量任务。对类似的河道测量工作有一定的参考价值。

In a certain region,GPS continuously operational reference system (CORS)can simultane-ously provide accurate and real-time differential positioning information for users,whith has been used widely in engineering surveying.In this paper taking Lousong River of Huai River to North Water as the basic platform and Using CORS method,the belt map and vertical &horizontal section were completed through a series of work,and a mass of surveying data were processed and analyzed.The results can pro-vide accurate survey inginformation for measurement tasks efficiently and accurately.The method provides certain reference value for the similar river measurement.
