摘要
针对上海世博会对黄浦江航道核心水域高精度海底地形的需求,采用SeaBat8125多波束测深系统对该区域进行了全覆盖测量。通过潮汐基准面归算、潮汐改正精度内符合检验、原始数据各项改正、除噪处理及测深误差分析等几个步骤,得到基于吴淞零点的最终水深成果。各项检验表明,此次多波束测深成果质量满足实际需求。
To meet the requirements of the high-precision marine floor topography at the central water-area of the main channel of the Huangpu-river during the Shanghai World＇s Fair,the central water-area was completely coverage surveyed by the SeaBat8125 multi-beam bathymetric sounding system.After several corrections such as the reduction of the tidal datum plane,the self-calibration of the tidal correctional precision,the corrections aiming at the original data and the noise rejection,etc,the sounding achievement at zero point of Wu-song was obtained.Several testing results showed that the sounding achievement using the SeaBat8125 multibeam bathymetric sounding system satisfied the actual demand.
