ENC stands for Electronic Navigation Chart, which refers to a digital representation of a maritime area used for navigation purposes. It is an electronic replacement for traditional paper nautical charts and is primarily used in marine navigation systems.
An ENC provides accurate and up-to-date information about various aspects of the maritime environment, including water depth, contours, aids to navigation, hazards, and other relevant features. It is typically created and maintained by hydrographic offices or other authorized entities responsible for chart production.
ENCs offer several advantages over paper charts, including the ability to display real-time vessel position, automated route planning, and the integration of other electronic navigational aids such as Automatic Identification System (AIS) data. They can be displayed on Electronic Chart Display and Information Systems (ECDIS) or navigation software installed on computers or specialized navigation devices.
To ensure the accuracy and reliability of ENC data, international standards and specifications have been established, such as those provided by the International Hydrographic Organization (IHO) and the International Electrotechnical Commission (IEC).
ENCs are widely used by professional mariners, including commercial shipping companies, naval forces, and recreational boaters. The availability and use of ENC data contribute to safer and more efficient navigation, reducing the risk of accidents and improving voyage planning.
