摘要
利用网络RTK导航定位、测深仪测深进行水下地形测量,结合使用水上测量软件进行实时数据采集和数据后处理,探讨了水下地形测量的一种新方法,并分析了测量成果的精度与粗差处理等有关的几个问题。
With the use of the network RTK navigation and depth-sounder in the underwater topographic survey,and combined with the hydropro for real-time data acquisition and data processing,this paper research on a new method of underwater topographic survey,and amalyzes some problems about the accuracy of measuring success and gress errors handling.
