摘　　要：无论是近海海洋测绘还是内陆水域测绘,水下地形测量都是基础手段,其形成的水下地形数据为港口建设、水利工程、抗洪防汛、水域综合治理等工作提供基本的数据支撑和保障。随着GNSS技术和似大地水准面精化技术的发展,无验潮模式开始广泛应用在各领域水下地形测量作业中。文章结合工程实践经验,分析了无验潮模式水下地形测量误差的形成过程,并对此提出了减小误差的优化方法,为开展水下地形测量提供有益借鉴。Whether offshore marine mapping or inland water mapping,underwater topographic survey is the basic means,and the underwater topographic data provide basic data support and guarantee for port construction,water conservancy projects,flood control,comprehensive management of water areas and so on.With the development of GNSS technology and quasi-geoid refinement technology,the non-tidal model has been widely used in underwater topographic survey in various fields.Combined with practical engineering experience,this paper analyzes the formation process of underwater topographic survey error in nontidal mode,and puts forward an optimization method to reduce the error,which provides a useful reference for underwater topographic survey.
