摘要
随着全球定位系统(GPS)的广泛应用,使港口工程大范围、高精度的水深测量成为可能,水位改正是港口工程水深测量中的必要工序,在处理实时水深测量数据时必须慎重选择合理的水位改正方法。根据多年港口工程水域测量的实践经验,提出3种实用性较强的水位改正方法,有利于提高感潮水域港口水深测量的精度和数据处理效率。
Since Global Positioning System （GPS） is widely applied in the world, water-depth measurement may satisfy the requirement of higher precision and larger measuring range. The water level correction is a necessary process of water-depth measurement of harbor engineering. The water-level correcting method should be carefully selected so as to process real-time data on water depth measurement. By summarizing the experiences on water area measurement of harbor engineering over years, three water-level correcting methods are proposed due to their higher practicability, which can improve the efficiency of processing water level measuring data and the precision of harbor wnt,~r-A,~,,~h
