摘　　要：多波束采集的海底地形数据具有海量性与冗余性特征,海量的多波束数据不利于海底DEM构建与水深图生产。因此,对于离散的多波束测深数据,行之有效的抽稀算法在多波束测深数据处理与水深图制图中尤为重要。本文介绍了常用的数据抽稀软件南方CASS、Fledermaus以及CARIS的原理与方法,并对比分析了各个软件的数据抽稀结果,在一定程度上为后续的科学研究与工程建设提供参考。Multi-beam bathymetric data have the characteristics of massive quantity and redundancy,which are not conducive to the construction of seabed DEM and bathymetric chart production.Effective thinning algorithm is particularly important in multi-beam bathymetric data processing and mapping.The principles and methods of commonly used data thinning software are introduced in this paper,including CASS,Fledermaus and CARIS.In addition,the thinning results of each software are compared and analyzed.This paper provides a reference for the follow-up scientific research and engineering construction.
