| 摘 要： | 分析了海底地形测量成果的多源异构和海量特性,指出合理构建交叉点不符值数列是开展数据质量评估及精化处理的关键。为避免格网法结果自身失真可能对评估造成的不确定性,充分准确挖掘交叉点不符值所隐含的粗差及系统性偏差等信息,提出应基于三角网构建海底地形曲面并计算全部水深交叉点不符值。结果表明,交叉点不符值数列构建结果具有唯一性,基于此可对海底地形成果可能隐含的误差作进一步探测并削弱。

| Abstract: | The multi-source heterogeneous and magnanimous characteristics of the bathymetric surveying products are analyzed,therefore the design of the cross point discrepancy array is the key step to the data quality assessment and the data purification.To avoid the uncertainty of the data assessment using the gridding method,the gross errors and systematic deviation included in the cross point discrepancy must be accurately acquired.So the triangulation nets are applied in the construction of the bathymetric surveying curves,and the cross point discrepancy of the depth is calculated in this paper.The result shows that the design of the cross point discrepancy array is unique and the errors included in the cross point can be detected and weakened on this basis. |
