摘要
为了解决多波束无验潮水深测量Caris数据处理中垂直基准模型的构建问题,基于EGM2008模型,通过插值算法建立了测区范围内深度基准面的大地高模型。通过实例讨论了构建深度基准面的大地高模型的步骤和方法。结果表明:该模型构建方法正确,模型内符合精度为3cm左右,外符合精度为10cm左右,能够满足区域范围内多波束无验潮水深测量的需要。
In order to solve the problem of building the vertical datum model in the CARIS data processing of the multibeam bathymetric survey without tidal observation.Based on EGM2008 model and through the interpolation algorithm, this paper introduces the establishment of the geodetic datum of chart datum within the scope of measurement area.This paper discusses the steps and methods of the building model by instance.The results show that the method of building model is correct, and its inner precision is about 3cm. Its outer precision is about 10cm.It can satisfy the needs of the regional bathymetric survey without tidal observation.
