摘要

摘要电子航海图（ENC）可以使用现有的纸质海图进行编制，以提高其对世界海洋的覆盖率。但是，在ENC上分配符号的过程中，在某些情况下，软件会将相同的符号用于不同的纸质图表符号。这最终可能危及海上安全。针对这个问题，本文描述了一种开发新工具的方法，该工具补充了使用纸质图表高效生产ENC。首先，ENC产品是使用CARIS S-57 Composer生产的。考虑到在编译过程中分配符号的困难，引入了一个新的web应用程序SYMO EXPERT。它是使用Firebase实时数据库和React应用程序开发的。编制了一份问卷，以收集有关使用SYMO EXPERT的时间因素和准确性的数据。结果表明，它支持用户有效地选择相关符号，准确率高达98%。

Resolving problems in symbol identification in compilation of electronic navigational charts utilising paper charts

Abstract Electronic navigational charts (ENCs) can be compiled using existing paper charts to improve their coverage of the world's oceans. However, in the process of assigning symbols on ENCs, in some cases the software uses the same symbol for different paper chart symbols. This could ultimately compromise maritime safety. Addressing this issue, this paper describes a methodology for developing a new tool that complements the efficient production of ENCs using paper charts. First, the ENC product was produced utilising CARIS S-57 Composer. After considering the difficulties in assigning symbols through the compilation process, a new web application named SYMO EXPERT was introduced. It was developed using Firebase Realtime Database and React app. A questionnaire was prepared to collect data about the time factor and accuracy of using SYMO EXPERT. Results showed that it supports the users in selecting relevant symbols efficiently with an accuracy of up to 98%.

期刊介绍： The Journal of Navigation contains original papers on the science of navigation by man and animals over land and sea and through air and space, including a selection of papers presented at meetings of the Institute and other organisations associated with navigation. Papers cover every aspect of navigation, from the highly technical to the descriptive and historical. Subjects include electronics, astronomy, mathematics, cartography, command and control, psychology and zoology, operational research, risk analysis, theoretical physics, operation in hostile environments, instrumentation, ergonomics, financial planning and law. The journal also publishes selected papers and reports from the Institute’s special interest groups. Contributions come from all parts of the world.
