| 摘 要： | 针对航海用数字水深模型DDM和非航海用DDM所采用的质量评估指标的不同,分析了DDM的重建过程与质量指标的评估方法,理论推导了航海用DDM所用深度保证率、深度表达度和非航海用DDM所用中误差之间的关系,并通过试验海区验证了航海与非航海用DDM质量指标随DDM的整体偏差值变化而变化的规律。

| Abstract: | Aiming at the difference of digital depth model quality index between navigational and non-navigational services, the reconstructing digital depth model and the estimating method of quality index were analyzed. The rela-tions among probability of an adequate depth, representiveness of depth of navigational services and root mean square error of non-navigational services based on digital depth model were derived. Experimental results demon-strate that quality index of digital depth model between navigational and non-navigational services has a regular change along with the whole deviation value. |
