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.
