Accuracy Analysis of Bathymetry for Prototype Observation of the Yangtze River Waterway
In order to scientifically and reasonably analyze the bathymetry results of the prototype-observation of the Yangtze River waterway,the accuracy indexes of the bathymetry results of the Yangtze River waterway should be achieved according to different technical standards are demonstrated.The importance of the mean error indicator is highlighted,and the correlation between the mean error and the tolerance and uncertainty specified by different specifications and standards is derived.An experiment for evaluation of the accuracy of the bathymetry in the observation network is designed.The experimental results show that the bathymetry results of the prototype observation of the Yangtze River waterway can achieve centimeter level accuracy,far exceeding the requirements of relevant specifications and standards.
