| Abstract: | Aimed at the multibeam sounding data of single sea route, a method for block thinning, zone modeling and splicing integration is presented in the paper. The method can not only improve building submarine DEM of anomalous multibeam sounding data effectively, but also enrich the measures of acquiring the data of submarine DEM. By the experiment, the method is proved to have the characteristics of simple structure, convenient operation, small footprint and high efficiency, which turns the construction of submarine DEM of multibeam sounding data into reality. |
