The structure and content of this third edition has been designed to meet the specific needs of the ECDIS community. This book goes beyond the scope of an ordinary textbook, will serve ECDIS-users, trainers and students alike. The subject is dissected into every detail imaginable.

The target audience includes ECDIS-users (navigators, ship-owners), manufacturers, data providers, hydrographers, maritime authorities, trainers and students.


The book is structured into five major parts, each building sequentially upon the previous:

        Part A (Chapters 1 - 6) introduces the subject and explains the basic fundamentals that make up an ECDIS, ranging from architecture to electronic-chart data structure and methods of display.

        Part B (Chapter 7 - 13) describes the primary functions of ECDIS and its practical use, presenting a comprehensive account of ECDIS use in practice, including its potential, requirements and limitations from the point of view of a navigator. ECDIS functioning is explained based on the ECDIS fundamentals.

         Part C (Chapters 14 - 15) details the means and process of providing the electronic chart data required to use ECDIS worldwide. This includes official services for ENC data provision, distribution and updating.

         Part D (Chapters 16 - 18) discusses ECDIS training. It gives guidance on how to design training courses, including simulator training, supported by ECDIS Demonstration software developed by Transas Marine. The IMO ECDIS training requirements and a cross-reference between training subjects and book chapters are given in the Appendix.

        Part E (Chapters 19 - 24) describes key aspects of ECDIS beyond its practical use, such as adequate backup arrangements, safety issue considerations, regulatory and legal implications, and some economic aspects.

The book concludes with an overview of supplementary information layers and other uses of ECDIS, and an outlook on future development.
