3. What is ECDIS ?
ECDIS is an advanced navigation information system for use in ships.
It has been developed to lighten considerably the navigation workload, freeing the mariner for other important navigation-related tasks such as maintaining a safe lookout and for collision avoidance.
It is a real-time decision aid, which provides the navigator with accurate and reliable information about a ship’s position and its intended movements in relation to charted navigational features

4. IMO MODEL COURSE FOR ECDIS

5. MAIN FUNCTIONS OF ECDIS
Navigation: determination of the position and course of the ship, execution of course alternation,
Monitoring: constantly checking information from instrument displays and the environment in order to detect any irregularities,
Route Planning: pre-determination of the course and speed in relation to the waters to be navigated and the task to be performed,
Route Monitoring: continuous surveillance of the ship’s sailing in relation to the pre-planned route and actual conditions,
Collision Avoidance: detection and determination of the motion and heading of other objects; execution of manoeuvres to avoid dangerous situations,
Manoeuvring: handling of the vessel to obtain the desired position, heading or speed,
Docking: manoeuvring the vessel alongside a berth,
Documentation: recording data and events for statistical and legal purposes.

6. MAIN FUNCTIONS OF ECDIS
to contribute to safe navigation,
to come to assistance in decision-making,
to reduce the navigational workload,
to execute in convenient and timely manner at least all navigational routines currently maintained on the paper chart,
to be legal equivalent to the paper nautical chart required by regulation V/27 of the SOLAS Convention.

7. SOLAS, Chapter V Regulation 2, paragraph 2:
“Nautical chart or nautical publication is a special-purpose map or book, or a specially compiled database from which such a map or book is delivered, that is issued officially by or on the authority of a Government, authorised Hydrographic Office or other relevant government institution and is designed to meet the requirements of marine navigation”

8. SOLAS, Chapter V
Under Regulation 19, paragraph all ships shall have nautical charts and nautical publications.
ECDIS with official ENCs may be accepted as meeting the chart carriage requirements.

9. COMPLETE SYSTEM FOR NAVIGATION WITHOUT PAPER CHART
Requirements to:
Computer (Including screen and keyboard)
Software (Meets the requirement of the S52 standard for presentation)
ENC (Electronic Nautical Chart)

10. COMPONENTS OF ECDIS

11. ECDIS Electronic Chart Display and Information System (ECDIS)
means a navigation information system
which, with adequate back-up arrangements
can be accepted as complying with the up-to-date chart required by regulation V/20 of the 1974 SOLAS Convention,
V/27
by displaying selected information from a system electronic navigational chart (SENC) with positional information from navigation sensors
to assist the mariner in route planning and route monitoring
and by displaying additional navigation-related information.

12. ENC Electronic Navigational Chart (ENC) means the database
standardised as to content, structure and format
issued for use with ECDIS
on the authority of government-authorized hydrographic offices.
The ENC contains all the chart information necessary for safe navigation,
and may contain supplementary information in addition to that contained in the paper chart (e.g. sailing directions),
which may be considered necessary for safe navigation

13. SENC System Electronic Navigational Chart (SENC) means a database
resulting from
the transformation of the ENC by ECDIS
for appropriate use,
updates to the ENC by appropriate means,
and other data added by the mariner.
It is this database that is actually accessed by ECDIS for the display generation
and other navigational functions,
and is the equivalent to an up-to-date paper chart.
The SENC may also contain information from other sources.

14. Electronic Charts Two Categories of Display
ECDIS
ECS
Two types of Electronic Charts
Raster
Vector

15. What is a chart in SOLAS? Effective 1 July 2002
Chapter V regulation 2.2:
Nautical chart or nautical publication is a special-purpose map or book, or a specially compiled database from which such a map or book is derived, that is issued officially by or on the authority of a Government, authorized Hydrographic Office or other relevant government institution and is designed to meet the requirements of marine navigation.

16. SOLAS V Chart Carriage effective 1 July 2002
Chapter V regulation
Nautical charts and nautical publications to plan and display the ship’s route for the intended voyage and to plot and monitor positions throughout the voyage; an Electronic Chart Display and Information System (ECDIS) may be accepted as meeting the chart carriage requirements of this subparagraph;
Chapter V regulation 27
Nautical charts and nautical publications, such as sailing directions, lists of lights, notices to mariners, tide tables and all other nautical publications necessary for the intended voyage, shall be adequate and up to date.

17. BEFORE ECDIS

18. How it will work? Charts will be stored on CD-ROMs and called Digital Nautical Charts. Electronic navigational charts are of two varieties: raster and vector.

19. PAPER CHARTS
fixed scale sheet,
fixed symbol definition,
fixed symbol arrangement and application with respect to North,
limited paper size,
limited types and amount of information,
limited number of colours and combined use.

20. ELECTRONIC CHART fixed display size, fixed resolution,
variable display scale,
variable types and amount of information,
various orientation with respect to North,
various symbol arrangement and application,
various symbol definition,
various number and use of colours.

21. The Basic Difference
Raster charts are simply bitmap images created by scanning a paper chart
Vector charts portray charted features as points, lines, or areas with amplifying information (attributes) found in an associated database

22. Raster Model
Shoreline
Water
Land
Vector Shoreline

23. Raster Chart’s Advantages and Disadvantages
Looks like the map.”/ Standard Appearance
Dumb Map: Very Little Ability for Automated Analysis
Less Efficient Storage
Zoom function restricted by pixel size
Much Easier/Cheaper/ Faster to Produce

24. Vector Chart’s Advantages and Disadvantages
Approximate look of the map/ User-Defined Appearance
Smart Map: Can Allow Very Powerful Automated Analysis
More Efficient Storage of Information
Zoom function not restricted
Time/Manpower Intensive to Produce

25. AFTER ECDIS

26. Ship/Shore communication
Required information for any voyage

27. CHART UPDATING

28. CD-ROMs including vector charts S-57, issued by RENC Primar: BASE CD - with full set of charts and weekly edited UPDATE CD – with updates (corrections)

29. IMPROVED ECDIS /ECS Dynamic information
Temporary changes in navigation objects (Beacon light is out, buoy has moved, underwater work etc)
Weather information
Sea level information
Routing system
AIS (Automatic Identification System)
VTS information
