Electronic Navigation Chart (ENC)

An Electronic Navigation Chart (ENC) is a digital map used by mariners to navigate safely. It provides detailed, up-to-date information about water depths, coastlines, navigational aids, hazards, and other essential data. ENC is used with electronic chart display and information systems (ECDIS), replacing paper charts, enabling real-time updates and precise plotting of a vessel’s position. This technology enhances safety, efficiency, and situational awareness during maritime navigation by integrating geospatial data into a digital format that supports advanced route planning and monitoring.
