摘要
GPS-RTK技术和数字测深仪在水下地形测量中的结合,能够实现在计划线上按距离或时间间隔自动采集水下地形点的三维坐标,不必进行验潮改正,数据成果可直接应用到专业绘图软件中成图。因其采集数据的密度高又保证了成图精度,极大的提高了测量效率。
Based on the cordination of GPS-RTK technology and digital sounder in underwater topographic survey,underwater topographic point 3D coordinates can be acquired automatically according to the distance or time interval on planning line,which does not need tide correction.The data results can be directly applied in the professional drawing software to produce map,which not only improves the work efficiency,but also ensures the mapping accuracy because of its high density of data gathering.
