The ECDIS Manual - 2019 edition

This new edition of the ECDIS Manual is an up-to-date guide to the use of electronic chart display and information systems. It sets out the current regulatory resolutions and compliance requirements and then looks in detail at the use of electronic charts and ECDIS software and functions.

Understanding ECDIS and selecting the right ECDIS solution is vital for ensuring the safe and precise navigation of a vessel on track, and on time. The ECDIS Manual, written by and for ECDIS navigators, draws on the knowledge of leading ECDIS experts and manufacturers, as well as calssification societies and NGOs, to support a vessel's transition to digital navigation in accordance with IMO, IHO, Flag State, PSC, ISM, SMS and SIRE requirements.


This publication is a comprehensive guide to the use of ECIDS systems. It outlines the history and development of digital navigation and provides detailed explanations of electronic charts and operating systems, supplemented by over 500 screenshots and colour images. It includes familiarisation checklists for a number of different systems, as well as the CIRM GL-001 Guideline for ECDIS Performance Test Procedure. The book also summarises the contributory factors in several ECDIS-related incidents.
