NOAA Electronic Navigational Chart |
The Office of Coast Survey (OCS) produces NOAA Electronic Navigational Charts (NOAA ENCŪ) to support the marine transportation infrastructure and coastal management. NOAA ENC®s are in the International Hydrographic Office (IHO) S-57 international exchange format, comply with the IHO ENC Product Specification and are provided with incremental updates, which supply Notice to Mariners corrections and other critical changes. NOAA ENC®s are available for free download on the OCS website. To download NOAA ENCs in the S-57 format for navigational purposes, please click here.
The NOAA ENC® supports 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 ENC®s support real-time navigation, as well as the collision and grounding avoidance needs of the mariner, and accommodates a real-time tide and current display capability that is essential for large vessel navigation. NOAA ENC®s also provide fully integrated vector base maps for use in geographic information systems (GIS) that are used for coastal management or other purposes.
For technical questions about the NOAA ENCŪs, the format or the
standards involved; and for questions related to production scheduling
or cartographic content of the NOAA ENCŪs, please click
