Extension of Coding CEVNI Signs and Marking for European Waterways

Abstract

This paper presents a new method of coding for signs and marking, which is based on the extension of signs and marking described in Annexes 7 and 8 of the European Code for Inland Waterways (CEVNI). Being members of three European expert groups, we have proposed these new codes of waterway signs and marking and recommend them for cases where they can be efficiently used. The main goal is to enable the use of these codes in databases, GIS systems and Web applications for efficient maintenance of waterway information. In addition, they will also contribute to international data exchange for creating standardised electronic messages described by ERI and NtS working groups. The intention is not to amend the existing coding from the Inland ECDIS Standard, which was developed for creation of Electronic Navigation Charts (ENCs). For example, the use of these new codes is tested through the Web GIS application for presentation of inland waterway signs and marking on the Danube River in Croatia. The application examples concern automatically generated reports on the position, characteristics and functioning of different waterway signs and river navigation marking located on the digital map.
