多波束数据质量等值线的水深不确定度表征法

Isoline Representation Method of Multibeam Sounding Data Quality Based on Total Vertical Uncertainty

采用不确定度理论进行评估是目前多波束测深数据质量的一个新的研究热点。基于国际海道测量标准(S-44),分析了适用于海道测量数据处理的不确定度评估方法;提出了基于多波束测深数据水深不确定度的数据质量等值线表征法。通过采用实例进行分析与评定表明,该方法为准确直观地评估多波束测深数据质量提供了理论依据和参考。

The methods of estimating multibeam data quality based on uncertainty is becoming a new hotspot presently. On the basis of the IHO Standards for Hydrography（S-244）, the evaluating methods of uncertainty for Hydrography data processing were analyzed, and the isoline representation method of multibeam sounding data quality was put forward. Experimental results indicated that the method for describing and evaluating the uncertainty of multibeam sounding data was credible.
