What is the primary function of the Electronic Chart Display and Information System (ECDIS)?

The primary function of the Electronic Chart Display and Information System (ECDIS) is to display navigational information on electronic charts. This system serves as a vital tool in modern maritime navigation by integrating data from various sources such as GPS, radar, and other navigational sensors. ECDIS enhances situational awareness for navigators by providing real-time updates on the vessel's position and surrounding maritime environment, allowing for informed decision-making. It also includes functionalities like route planning, monitoring of safe water and hazards, and compliance with maritime regulations. By utilizing electronic charts, ECDIS helps streamline navigational processes, reduce human error, and improve overall safety at sea.
