Electronic Chart Display and Information System (ECDIS) is a specialized navigation system used on ships. It combines electronic charts with navigation data, allowing ship officers to visualize their position, course, and surrounding environment.

The ECDIS course focuses on using ECDIS to maintain safe navigation. It covers various aspects of using the system, including interpreting charts, planning routes, and responding to emergencies.

To join the ECDIS course, you need some prior knowledge of navigation, including experience using navigation tools, and basic computer skills.

The course includes a final exam that assesses your understanding of ECDIS. This exam is a combination of theoretical and practical components.

To pass the ECDIS course, you need to achieve a minimum score of 60% on the final exam.

The ECDIS course curriculum is a joint effort between the Ecole Nautique, Antwerp Maritime Academy, and VDAB Maritieme Opleidingen. This collaboration enhances the quality and relevance of the course.

The ECDIS course focuses on equipping individuals with the skills and knowledge to effectively use ECDIS as part of safe navigation practices.

The ECDIS course combines theory with practical exercises, providing a well-rounded learning experience. This approach ensures students develop both theoretical understanding and practical application.

ECDIS can display radar information, but it should not affect the displayed nautical charts (ENC) in a negative way.

Integrated radar data that overlays the electronic chart, providing a permanent radar fix.

The radar image and position data are automatically adjusted to account for the difference between the ship's position and the radar antenna.

If the radar image of fixed objects doesn't match the ENC data, it might indicate an error in the ECDIS's positioning system, potentially in the geodetic datum.

The scale and orientation of the radar image and the electronic chart should match to provide a unified view.

A digital representation of a nautical chart used in ECDIS.

Performance standards for ECDIS were first defined in 1995 by IMO Resolution A.817 (19).

The primary function of ECDIS is to contribute to safe navigation, and its use should reduce navigational workload compared to paper charts.

ECDIS became mandatory for high-speed craft after a 2005 decision by IMO.

In 2009, IMO agreed to a program introducing the compulsory carriage of ECDIS for most types of merchant ships, starting from 2012.

SOLAS Chapter V was amended in 2002 to include provision for electronic means of navigation to meet chart carriage requirements.

The International Maritime Organization (IMO) is the UN agency responsible for maritime safety and environmental protection.

A symbol displayed on an ECDIS chart when there's insufficient data to fully represent a feature. It's indicated by a default symbol with a question mark.

A special type of feature in an ENC representing features without a specific object. Its definition is accessible via the Pick Report.

A simplified representation of a navigational aid on an ECDIS chart. It aims to be distinct and easy to distinguish on the screen.

The symbols used for buoys and beacons in ECDIS charts can be displayed in either traditional chart format or in a simplified format.

A type of buoy symbol for lateral, cardinal, isolated danger, and safe water buoys featuring a sloping topmark in the buoy's most distinctive color.

The simplified buoy symbol for special mark buoys is yellow.

The simplified symbol for mooring buoys resembles the traditional paper chart installation buoy symbol.

When an ENC doesn't have enough information to display a specific buoy symbol, a filled grey circle is used as the default.

Newly installed ECDIS equipment must meet the latest performance standards.

The international agreement setting the standards for training, certification, and watchkeeping of seafarers.

A detailed model course developed by the IMO for the operational use of ECDIS.

IMO Resolution A.694(17) establishes general requirements for shipborne radio equipment and electronic navigational aids, including ECDIS, to be part of the Global Maritime Distress and Safety System (GMDSS).

This IMO document highlights the differences between RCDS (Radar Chart Display System) and ECDIS.

This IMO document provides guidance on transitioning from paper charts to ECDIS navigation.

These IMO guidelines address ergonomic considerations for bridge equipment and layout, including ECDIS.

This IMO resolution establishes performance standards for the presentation of navigation-related information on navigational displays, including ECDIS.

This IHO document specifies detailed requirements for chart content and display aspects of ECDIS.

This IHO standard defines the transfer format for digital hydrographic data used by ECDIS.

True north is a geographical reference point, while gyro north is the direction indicated by a gyroscope. When overlaying radar data on electronic charts (ENCs), the rotation difference between true north and gyro north needs to be accounted for.

Sea stabilization refers to adjusting the display to compensate for boat movements on the water, while ground stabilization keeps the display fixed relative to the earth's surface. These settings can affect how effectively the radar overlay aligns with the electronic chart.

The scale of a map or chart represents the ratio between the distance on the map and the actual distance on the ground. Radar range determines how far the radar can detect objects. It's important for scales and radar ranges to be compatible for accurate overlays.

Electronic Chart Display and Information Systems (ECDIS) use priority layers to organize information. Radar data is displayed in priority layer 7, meaning it's less important than other chart information.

The relationship between different data layers in ECDIS can make it difficult to display too much information in one place. For example, if the radar overlay is not easily distinguishable, it can be confusing for mariners.

ECDIS prioritizes chart information over radar data. This means that chart data will always be visible, even when radar information might be obscured or hidden.

To prevent information overload in ECDIS, there is a radar off-switch. This allows mariners to temporarily disable radar data from the display.

To ensure consistent overlay of radar data on electronic charts, Hydrographic offices are encouraged to use standard scaling principles. This table highlights the standard scale recommendations for various radar ranges.
