Abstract

Based on the current quality detection methods and development direction of digital chart, a Chart quality detection method based on depth range constraints in isobath zones was proposed for a large number of water depth points and isobates on digital chart. Firstly, in view of the defects existing in the current quality detection method, the current different quality detection methods are compared and analyzed. Then, the logical error of the chart data is studied. Through experimental calculation, the weight of the depth range extraction is determined. The experimental results show that the proposed method can effectively improve the accuracy of logical detection.
