摘　　要：在航道测量中,水下地形测绘是一项重要的工作。与传统RTK测量相似,在进行水下地形点的测量时通过RTK获取测量点水面三维坐标,结合测深仪测得的实时水深,组合计算出的水下地形点三维坐标。通过水深测量得到的真实水底地形,能为航道的整治研究、内河航运、码头建设和防洪防灾等提供必需的地理信息。In waterway survey,underwater topographic mapping is an important work.Similar to the traditional RTK survey,the three-dimensional coordinates of the water surface of the underwater topographic point are obtained by RTK,and the three-dimensional coordinates of the underwater topographic point are combined with the real-time water depth measured by the sounder.The real underwater topography obtained by bathymetry can provide necessary geographic information for waterway regulation research,inland navigation,wharf construction,flood control and disaster prevention.
