Official NOAA ENCs may be obtained from the International Centre for Electronic Navigational Charts (IC-ENC) through a Value Added Reseller Army Corps of Engineers produces Inland ENCs for many U.S. coastal waters and the Great Lakes, which all comply with the International Hydrographic Organization S-57 ENC Product Specification. NOAA maintains complete coverage of NOAA ENCs over U.S. The benefits of NOAA ENCs include: being easy to update offering greater detail than paper charts utilizing layers that can be turned on and off to reduce cluttered displays and remaining correctly oriented at all times.īy offering increased detail and making navigation information more accessible, ENCs can provide an added level of safety for the modern mariner. They display all of the navigation information found on traditional paper charts, while also facilitating real-time ship positioning and helping with collision and grounding avoidance. NOAA ENCs are vector data sets that support all types of marine navigation. They can even be accessed by recreational boaters on smartphones and tablets. Originally designed for large commercial vessels using a sophisticated navigational computer called an electronic chart display and information system (ECDIS), ENCs are now also being used on simpler electronic chart systems and chart plotters on many types of ships. More information on the transition from NOAA paper nautical charts to ENC-based products can be found in the Sunsetting Traditional NOAA Paper Charts document and the Farewell to Traditional Nautical Charts webpage.Įlectronic navigational charts (ENC) are NOAA’s primary nautical chart product. Mariners that prefer paper charts can use NOAA’s Custom Chart application to create charts directly from NOAA ENC data. NOAA is currently in the process of transitioning away from traditional paper nautical charts to focus on producing electronic navigational charts (NOAA ENC ®). They represent one of the most fundamental tools available to mariners. Specifically tailored to the needs of marine navigation, nautical charts delineate the shoreline and display important navigational information, such as water depths, prominent topographic features and landmarks, and aids to navigation.
