测深仪结合GPS在水文站大断面测量中的应用初探

Study on Combining the Depth-with GPS for Measuring the Large Sections of Hydrometric Stations

利用梧州水文站实测点和大断面的空间几何关系,对船载HD370型测深仪结合GPS采集数据进行后处理分析研究。结果表明,测深仪结合GPS数据可应用于绘制大断面成果。

this paper analyzed and studied the data collected by the shipborne HD370 Echo sounder, combined with GPS. When analy- zing the above data, the geometric spatial relations between the Wuzhou hydrometric station and its associated large section are utilized. The results indicates that the above data can be used for drawing the large section.
