Abstract

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%.

解决利用纸质海图编制电子海图时的符号识别问题

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%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
