An Electronic Navigation Chart (ENC) is a digital representation of maritime navigation charts used by ships and boats. ENCs provide essential information about water depths, navigational aids, and potential hazards, helping mariners navigate safely. They are standardized and produced according to the International Hydrographic Organization (IHO) specifications. ENCs are typically displayed on electronic devices such as Electronic Chart Display and Information Systems (ECDIS). These systems allow for real-time updates and integration with other navigational data, enhancing situational awareness. The use of ENCs improves efficiency and safety in maritime navigation, reducing the risk of accidents at sea.
