【摘要】 综合考虑水深点不确定度信息和距离对格网节点的影响,提出了利用不确定度和距离联合确定权函数方法构建海底数字高程模型(DEM)。利用不确定度信息传递模型和海底DEM格网分辨率选取标准,在DEM精度和数据容量之间保持平衡,为生成多种形式、满足多种需要的海洋数字产品提供了基础。更多还原

【Abstract】 The effect of soundings uncertainty information and distance to grid nods is considered,a technique of Submarine digital elevation model(DEM) construct method from multibeam data by weight function which combine uncertainty information and distance is presented,which have preferable precision.Uncertainty propagation model and DEM grid resolution standard give chance preserving suffice raw information of soundings,and provide the base of product multiform ocean numeric productions.更多还原
