The Electronic Chart Display and Information System (ECDIS) is a geographic information system for voyage planning and route monitoring to support the safety navigation of ships at sea. And in response to the latest revision of the International Convention for the Safety of Life at Sea (SOLAS), the International Maritime Organization (IMO) enforced the mandatory installation of the ECDIS by July 2017 according to vessel’s category.(Requirements for the equipment and operation qualification are subject to approval from the country with which the ship is registered and recommendations from the classification society of the ship.)
The ECDIS onboard a ship uses information from the automatic identification system (AIS) and superposes the images with navigational chart information, thus accurately displaying dynamic information on other ships around. Also the ECDIS plays central roles in the safe navigation of the ship and provides safety functions, including the generation of warnings when the ship approaches dangerous areas. The ECDIS is useful for marine accident avoidance and serves as equipment indispensable to the safe navigation of ships.
