Electronic Chart Display and Information Systems (ECDIS) is a computer-based navigation system used on ships. It integrates electronic navigational charts with various data sources, such as GPS and radar, to provide real-time information about a vessel's position and surrounding environment. ECDIS enhances safety by allowing mariners to visualize their route and identify potential hazards. ECDIS is recognized as a standard for maritime navigation and is often required by international regulations. It helps streamline the planning and monitoring of voyages, making it easier for crews to comply with safety protocols and maritime laws, such as those set by the International Maritime Organization (IMO).
