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。Aiming at the difference of digital depth mode] quality index between navigational and non-navigational services, the reconstructing digital depth model and the estimating method of quality index were analyzed. The relations 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 demonstrate that quality index of digital depth model between navigational and non-navigational services has a regular change along with the whole deviation value.
