Seabed DEM Construction Based on Uncertainty

    Graphical Abstract
    • 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.
