摘要

摘要与测深数据相关的不确定性的估计对于确定数据采集的质量至关重要。该估计基于协方差传播，考虑了经典的测深地理参考模型。文献中充分描述了使用总传播不确定性（TPU）模型估计不确定性。在该模型的基础上，本研究分析了海底形态对测点不确定性值的影响。加深对海底对测深数据不确定性值的影响的理解，将改进对海底表面以及海底结构的处理和解释。

An Empirical Study of the Influence of Seafloor Morphology on the Uncertainty of Bathymetric Data

Abstract The estimation of the uncertainty related to bathymetric data is essential in determining the quality of the data acquisition. This estimation is based on the covariance propagation considering the classical sounding georeferencing model. The estimation of the uncertainty using the Total Propagated Uncertainty (TPU) model is well described in the literature. Developing on this model, this study introduces an analysis of the morphological influence of the seafloor on the uncertainty value of the sounded points. Advancing the comprehension of the influence of the seafloor on the uncertainty value of the bathymetric data would improve the processing and interpretation of the seafloor surface as well as the structures present on the seafloor.
