Abstract This work aims at providing geoscientists with a new robust shape transform that performs the estimation of a smooth submarine intra-sediment shape from Multi-Beam Echo Sounders data. This shape matches a virtual geodesic interface between mobile and immobile sand, called an osculatory surface. The transform operates through only two non-optional parameters: its scale length and the corresponding degree of the local representations. Application tests addressing different tidal sandbanks are described. Applications to the osculatory tracking of two monitoring zones over fifteen years are also included.

接触面提取应用于海底砂材料监测

摘要 这项工作旨在为地球科学家提供一种新的鲁棒形状变换，该变换可以从多波束回波测深仪数据中估计平滑的海底沉积物内部形状。这种形状与可移动和不可移动沙子之间的虚拟测地界面相匹配，称为接触面。变换仅通过两个非可选参数进行操作：其尺度长度和局部表示的相应程度。描述了针对不同潮汐沙洲的应用测试。还包括在 15 年内对两个监测区进行接触跟踪的应用。
