摘　　要：针对航渡式水深测量资料海量、条带式分布的数据特点,提出了分块抽稀、区域建模、拼接整合的海底地形DEM建模思路,可有效提高不规则形状水深资料的建模效率,丰富海底地形DEM获取手段。实验证明,该方法具有结构简单、操作便利、内存占用少、计算效率高等特点,能够实现基于航渡式水深数据的海底地形DEM建模。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.
