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.

The NOAA electronic navigational chart (NOAA ENC) files that may be downloaded from the National Oceanic and Atmospheric Administration (NOAA) are official products. Official ENCs are suitable for navigation under the following regulations and policies, and in the following circumstances:On May 2, 2001, the United States Coast Guard amended the chart carriage regulations to permit government vessels to use electronic charting and navigation systems in lieu of paper charts.On August 15, 2002, the United States Coast Guard issued a statement of policy to bring its regulations into agreement with SOLAS Chapter V (as amended by the changes taking effect July 1, 2002). The policy statement said that, if a ship has an approved ECDIS installed according to SOLAS, Chapter V, the ECDIS will be considered as meeting the ship's nautical chart carriage regulations. The ships that are affected are:U.S.-flagged ships of 150 or more gross tons that engage on international voyages.U.S.-flagged ships certificated solely for service on the Great Lakes and the St. Lawrence River.Foreign-flag ships to which SOLAS, Chapter V, applies that are operating on the navigable waters of the United States.This policy is not applicable to U.S.-flag ships engaged only on domestic voyages. These ships must continue to comply with existing navigation equipment requirements until the chart carriage regulations are formally amended.The NOAA ENC files available from this site are updated for Notices to Mariners on at least a monthly basis. Users are encouraged to check the site frequently and download the latest versions of the files. Notice to mariner updates are either contained in a new edition ENC or an incremental update (also called ENC Revision or "ER" files).
