What does ECDIS stand for?

ECDIS stands for Electronic Chart Display and Information System. This system is vital for modern navigation as it integrates electronic navigational charts (ENC) with various data inputs, providing real-time information for navigators. By using electronic charts, mariners can enhance their situational awareness, improve the efficiency of route planning, and ensure compliance with maritime regulations.

The use of ECDIS has transformed traditional navigation practices, allowing for safer passage by presenting crucial navigational data such as depth, hazards, and weather conditions in a user-friendly digital format. This reduces the reliance on paper charts and enhances the ability to navigate through complex waterways. The ability of ECDIS to automatically update charts with the latest information also plays a significant role in maintaining safety at sea.

The other options refer to different concepts that do not align with the established definition of ECDIS in maritime navigation.
