| Abstract: | The principle and the process of GPS RTK in underwater topography measuring are introduced,and the impairing aspects of RTK in construction based on the application of depth souder in water conservancy projects is analyzed.Some relative measures are suggested to ensure the quality effectively and to avoid re-measuring to the maximum extent. |
