ABSTRACT: A Guideline on the Harmonised Portrayal of e-Navigation-related Information was recently completed by IALA. The purpose of this Guideline is to provide guidance regarding the presentation and display of e-Navigation-related information. The basic, over-riding premise of this Guideline is that shipborne and shore-based equipment, systems, and services should portray e-Navigation-related information to all users (both onboard and ashore) in a consistent manner. However, since e-Navigation is an evolutionary process, this goal-based guideline describes over-arching objectives to be achieved, while freedom to innovate is left to both developers and users. An explanation is provided about key aspects of the Guideline. In particular, a website has been established to show examples of useful ways to portray e-Navigation information for current as well as some future types of equipment, systems, and services.
