NOAA Electronic Navigational Charts (ENC)

Description

The Office of Coast Survey (OCS) has been involved in the development of a NOAA Electronic Navigational Chart (NOAA ENC) suite to support the marine transportation infrastructure and coastal management for a number of years. The NOAA ENC will support all types of marine navigation by providing the official database for electronic charting systems (ECS), including the Electronic Chart Display and Information System (ECDIS). NOAA ENCs support real-time navigation as well as collision and grounding avoidance needs of the mariner, and accommodate a real-time tide and current display capability that is essential for large vessel navigation. NOAA ENCs will also provide fully integrated vector base maps for use in geographic information systems (GIS) that are used for coastal management or other purposes. The NOAA ENCs are in the International Hydrographic Office (IHO) S-57 international exchange format and comply with the ENC Product Specification.

21 Individual NOAA ENCs may be downloaded from the Chart Downloader for NOAA ENC. The NOAA ENCs distributed here are a geo-referenced database(s) of NOAA nautical chart features and their attributes, published by NOAA in the format of the International Hydrographic Organization S-57 Standard, "IHO Transfer Standard for Digital Hydrographic Data." NOAA updates the ENCs for Notice to Mariners on a weekly basis (timing of their availability is not guaranteed). NOAA ENCs are an official product of NOAA. https://charts.noaa.gov/ENCs/ENCs.shtml

0 The NOAA Custom Chart application enables users to create their own customized charts directly from the latest NOAA ENC data. These charts contain all the same information as ENCs, but it is presented using the same symbols and colors used on traditional paper nautical charts. NCC outputs geospatially referenced Portable Document Format (PDF) files All recreational and professional mariners are encouraged to use NOAA's premier navigational product, the electronic navigational chart (ENC) for their primary means of navigation. NCC uses the latest up-to-date NOAA ENC data to create customized charts and these charts are especially useful for voyage planning and situational awareness. https://devgis.charttools.noaa.gov/pod
