【Other systems】 MBSB DL : 0: 多波束测深数据具有海量存储的特点，而目前国内工程上较为常用的测量绘图软件难以实现对海量数据的绘图和计算，因此，对多波束测深数据进行抽稀具有重要的现实意义。在抽取多波束水深数据时主要考虑到两点，首先要求抽取出的数据是真实的水深值，而不是插值后的结果，其次要求抽取后的水深点的空间位置分布均匀，因此我们选择等网格间距抽取。-Multibeam bathymetric data mass storage characteristics, more commonly used in domestic engineering surveying and mapping software currently difficult to achieve drawing and calculation of the mass data, therefore, the multibeam bathymetric data Rarefy to have important practical significance. In extracting the multibeam bathymetric data taking into account the two points, the first requirement is extracted data is a true depth value, instead of the interpolation results after second, require the spatial position of the point after decimation depth distribution uniformity, so we choose other network grid spacing extract.
