Harmonized Portrayal of e-navigation-related Information 10

1Introduction 10

2Background 10

3Scope 10

3.1Core Objectives 11



facilitate safe and secure navigation of vessels having regard to hydrographic, meteorological and navigational information and risks; 11

facilitate vessel traffic observation and management from shore/coastal facilities, where appropriate; 11

facilitate communications, including data exchange, among ship to ship, ship to shore, shore to ship, shore to shore and other users; 11

provide opportunities for improving the efficiency of transport and logistics; 11

support the effective operation of contingency response, and search and rescue services; 11

demonstrate defined levels of accuracy, integrity and continuity appropriate to a safety-critical system; 11

integrate and present information on board and ashore through a human-machine interface which maximizes navigational safety benefits and minimizes any risks of confusion or misinterpretation on the part of the user; 11

integrate and present information onboard and ashore to manage the workload of the users, while also motivating and engaging the user and supporting decision-making; 11

incorporate training and familiarization requirements for the users throughout the development and implementation process; 11

facilitate global coverage, consistent standards and arrangements, and mutual compatibility and interoperability of equipment, systems, symbology and operational procedures, so as to avoid potential conflicts between users; and 11

support scalability, to facilitate use by all potential maritime users. 11

While these core objectives appear to be straight-forward, what constitutes e-navigation information and how this information should be portrayed is more subjective. As it pertains to this Guideline, the "e" in e-navigation refers to "...electronic means to enhance berth to berth navigation and related services." As such, the intent is to provide practical guidance on how to achieve a "harmonized presentation" of e-navigation information both aboard and ashore. 11

6OPERATIONAL REQUIREMENTS 17

6.1Voyage Requirements 17



Strategic overview is associated with maintaining overall situational awareness within the surrounding areas. This can include both monitoring and active engagement. 17

Tactical involves more direct action and decision-support within the immediate or designated area. 18

6.2Situation Needs 18



Current situation includes the various phases of navigation during a voyage or can be related to the prevailing conditions. Examples of different navigation phases include open-ocean, coastal, and approach. Prevailing conditions include, daytime vs. nightime transits, calm vs. stormy weather conditions, good vs. poor visibility, light vs. heavy vessel traffic, etc.) 18

Regardless of the current situation, the Task-at-Hand can be the determining factor in what information is crucial to making informed decisions. This includes time-critical information necessary for grounding avoidance, collision avoidance, or maintaining overall situational awareness. 18

7BASIC GUIDANCE ON PORTRAYAL 20

7.1Six basic ways 20



alpha-numeric 20

graph 20

point, line or polygon 20

symbol 20

geo-spatial 20

imagery 20

7.1.1Alpha-numeric 20

7.1.2Graph 20

7.1.3Point, line, or polygon 20

7.1.4Symbol 20

Use consistent symbology across all displays 20

Uniqueness – only one possible meaning 20

Non-ambiguous – ability to determine differences (i.e. distinct) 20

Intuitively obvious – an easily recognized symbol, icon, or pattern 20

Have a basic symbol for different categories. Further attributes should be 20

enhancements (not changes) to the basic symbol. 20

7.1.5Geo-spatial 21

7.1.6Imagery 21

7.2Guiding Principles 21



The data content and format of e-navigation related data should be similar (e.g., GPS/DGPS, AIS ASMs, ENCs, etc.). However, how the data is displayed as ‘information’ depends on the particular tasks, function, and needs of the user. 21

There should be a means to achieve a similar portrayal of e-navigation information on key equipment/systems (e.g., ECDIS and radar). One possible means of achieving this is to have a default e-navigation portrayal mode that could be used to portray navigation-related information in a similar manner to that of shipborne displays. 21

The “portrayal of e-navigation information onboard ships or ashore does not necessarily have to be identical.” However, there is benefit to all users if information is displayed in a consistent and unambiguous manner. This includes the use of standard symbology, icons, and colour schemes. 21

With new types of e-navigation related information becoming available, there will a tendency to add more information to existing navigation displays (e.g., ECDIS and radar). Displaying too much supplemental information can obscure critical information or lead to confusion. 21

Scope of ECDIS 22

Application of these standards 22

Definitions 22

Connections with other equipment 22

Power supply 22

the display is clear and unambiguous 22

there is no uncertainty over the meaning of colours and symbols on the display, [by] establishing an accepted pattern for ECDIS presentation that becomes familiar to mariners and so can be recognized instantly without confusion. 23

Main Document – This describes the Specifications for Chart Content and Display Aspects of ECDIS the in relatively general terms (i.e., methods and requirements). 23

Annex A – The Presentation Library is separate document (see further explanation below), and provides specifies the colours, symbols, symbolization instructions, etc. together with guidance on how an ENC should be displayed on ECDIS. This annex has several components: 23

Part I contains chart objects, and an addendum which is a paper-based description of the symbol library as graphics. 23

Part II contains [recommended] Mariner’s Navigational Objects (e.g.,. own ship symbol, tracks, waypoints, time tags, etc.) 23

The ECDIS Chart 1 is also included with the Presentation Library as a graphic file, and is also available as a collection of the varying objects contained in a special cell in S-57 format containing generic feature objects. 23

Annex B - Specifies procedures for initial colour calibration of displays and the verification of that calibration. 23

Annex C - Specifies a procedure for maintaining the calibration of displays. 23
