Quality Detection and Control for Paper Chart Production & Updating Based on Standard Quality Database

The production and updating of paper chart is always the theme to the guarantee and improvement of hydrographic chart, in which the quality detection and control is the key to consider. At present, the production of paper chart has already achieved digital mapping with the widespread application of computer technology in the field of marine surveying and mapping. However, it is difficult to ensure the accuracy of the data of paper charts by the traditional quality detection and control methods for paper charts used currently because they have several problems such as much repeated work, low efficiency and a great of waste and so on. Aiming at above problems, a new method of quality detection and control for the production and updating of paper charts based on standard quality database is presented in this paper. This method takes a full account of the digital production technology, and achieves the quality detection and control for paper charts under digital conditions more rapidly and effectively. The prototype system based on the method presented in this paper has been developed, which can be used as a more effective tool than traditional methods to help to detect and control the quality of paper charts.
