What is the purpose of using an electronic chart display and information system (ECDIS)?

The purpose of using an electronic chart display and information system (ECDIS) is to assist in navigation and display nautical information. ECDIS serves as a crucial tool for mariners by integrating various data sources to create a comprehensive view of navigational charts, ensuring that navigators have the most up-to-date information regarding water depths, navigation aids, hazards, and other critical features relevant to safe navigation. It enhances situational awareness by allowing for real-time monitoring of the vessel's position, course, and speed, as well as providing safety features like automatic alerts for impending hazards.

The system is designed to improve efficiency and safety in navigation without completely replacing all navigational equipment, as modern navigation still requires traditional methods as backups. ECDIS does not serve entertainment purposes, nor is it specifically designed for measuring the speed of the vessel, which is typically done using separate speed measuring devices.
