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.

NOAA's Electronic Navigational Charts (NOAA ENCs) have been developed to support the marine transportation infrastructure and coastal management. The NOAA ENCs are in S-57, a data standard developed by the International Hydrographic Organization (IHO) to be used for the exchange of digital hydrographic data. NOAA ENCs can be used in Geographic Information Systems, (GIS) allowing for broader public access. Many GIS's, however cannot read an ENC's native S-57 format to address this problem. NOAA's ENC Direct to GIS web portal provides comprehensive access to display, query, and download all available large scale NOAA ENC data in a variety of GIS/CAD formats for non-navigational purposes using Internet mapping service technology. Nautical chart features contained within an NOAA ENC provide a detailed representation of the U.S. coastal and marine environment. This data includes coastal topography, bathymetry, landmarks, geographic place names and marine boundaries. Features in an NOAA ENC are limited in that they only represent the geographic region that is depicted in that particular NOAA ENC. By aggregating nautical features from all NOAA ENCs in the creation of GIS data, a contiguous depiction of the U.S coastal and marine environment is achieved.

Electronic Navigational Charts (ENC) are vector data sets that support all types of marine navigation. 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 and by recreational boaters. NOAA ENCs help provide real-time ship positioning, as well as collision and grounding avoidance.The NOAA Chart Display Service renders NOAA Electronic Navigational Chart (ENC) data with "traditional paper chart" symbols, labels, and color schemes familiar to those who have used NOAA paper nautical charts or the NOAA Custom Chart application.NOAA ENCs comply with the International Hydrographic Organization ENC Product Specification. ENCs are produced around the world by many different countries’ national hydrographic or charting agencies. NOAA maintains more than 1,000 NOAA ENC® datasets over U.S. coastal waters and the Great Lakes.Free updates for NOAA ENCs are available weekly, which provide critical changes as well as the routine addition of newly compiled data, such as hydrographic or shoreline surveys. The NOAA Weekly Chart Updates page shows the areas that have changed on each ENC since its last new edition was published.ENCs also provide vector base maps for use in geographic information systems (GIS) that are used for coastal management and other purposes. The NOAA ENC Direct to GIS service supports extracting ENC data into GIS supported formats.Note: This layer is a feature service, which means it can be used for visualization and analysis throughout the ArcGIS Platform. This layer is not editable.

NOAA Electronic Navigational Charts (NOAA ENC®) are in International Hydrographic Organization (IHO) S-57 format, which is the standard used for the exchange of digital hydrographic data. NOAA ENC Online optimizes the viewing of the entire ENC suite, using the display rules defined by the IHO S-52 Specifications for Chart Content and Display Aspects of ECDIS.

The NOAA Chart Display Service (NCDS) renders NOAA electronic navigational chart (NOAA ENC®) data with “traditional paper chart” symbology in online and offline applications for which a basemap of nautical chart data is desired, including GIS, web-based, and mobile mapping applications.The service uses symbols, labels, and color schemes familiar to those who have used NOAA paper nautical charts or the NOAA Custom Chart application. NCDS is available as Esri REST Map Service, OGC Web Map Service (WMS), and MBTiles formats.The ENC data in the service are updated weekly and include all of the latest Notice to Mariners corrections.

NOAA, National Ocean Service, Office of Coast Survey, Marine Chart Division is responsible to build and maintain a suite of more than 1000 nautical charts that are used by commercial and recreational mariners to navigate the United States and U. S. territory waters safely.A Nautical Chart is a graphic portrayal of the marine environment. They are used to lay out courses and navigate ships by the shortest and most economically safe route. They can also serve as base maps for resource management and shoreline development planning by state and local government.Charts depict the _location of the shoreline, minimum water depths, aids to navigation, hazards to navigation, the nature and form of the coast, water depths, the general character and configuration of the sea bottom, the rise and fall of the tides, protected areas, and the characteristics of the Earth's magnetism.The suite of charts is compiled and maintained with data provided by federal, state, and private partners such as the National Ocean Service elements, United States Coast Guard, United States Army Corps of Engineers, United States Power Squadron Auxiliary, Port Authorities.The charts are currently available as Lithographically printed paper charts, Electronic Raster Nautical Charts (RNCs), up-to-date paper charts (printed with print on demand technology), and are now offered as Digital Vector Electronic Nautical Charts (ENC).The NOAA RNCs are electronic images of the NOAA paper charts. The NOAA RNCs were productized with a successful Cooperative Research and Development Agreement (CRADA) with private sector partner BSB Electronic Charts, a subsidiary of Maptech, Inc. Andover, Massachusetts. As of November 1, 2005 the NOAA RNC's are available for free download via the NOAA website.

The National Oceanic and Atmospheric Administration (NOAA) Electronic Navigational Charts (ENC), found in the A-16 National Geospatial Data Asset Portfolio, 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. The NOAA ENC will support all types of marine navigation by providing the official database for electronic charting systems, including the Electronic Chart Display and Information System. NOAA ENCs will also provide fully integrated vector base maps for use in geographic information systems that are used for coastal management or other purposes. The NOAA ENCs are in the International Hydrographic Office S-57 international exchange format and comply with the ENC product specification. The ENC Harbor map service displays data compiled for ENC products with a scale range from street level (1:5,000) to town level (1:50,000).The ENC data used within this application will be updated weekly. This map layer is not intended for navigation purpose.Thumbnail image courtesy of: Kartverket

Ship wrecks and obstructions in the ocean have long been a hazard to navigation and construction, and a point of interest to archeologist, recreational divers, fisherman, educators and explorers. Locating hazardous wrecks and obstructions is part of the ongoing NOAA charting process. The exact position of many wrecks is difficult to determine because of changes in the environment, varied survey methods, and human error. Some wrecks are intentionally placed in the ocean to serve as artificial reefs or for disposal. Others pose a health and environmental threat from their cargo. Ownership and control over wrecks and obstructions is governed by a collection of state and federal regulations, the Abandoned Shipwreck Act, National Historic Preservation Act, and the National Marine Sanctuaries Act. These data are a synthesis of two sources - the NOAA Office of Coast Survey's 2016 Automated Wreck and Obstruction Information System (AWOIS), and the NOAA Electronic Navigational Charts (ENC). Not included were those records that were clearly identified as natural features such as rocks, shoals, and trees. Features are recorded as either a wreck, wreck area, obstruction, or unknown.

These data depict the occurrence of submarine cables in and around U.S. navigable waters. The geographic extent of these data is greater than the dataset provides. The purpose of these data products are to support coastal planning at the regional and national scale. These data are derived from 2010 NOAA Electronic Navigational Charts (ENCs) and 2009 NOAA Raster Navigational Charts (RNCs). Abandoned cables, or cables that have been removed may appear within this dataset. Features defined as cables were compiled from the original sources, exclusive of those features noted as 'cable areas'. Please note that this may not include all fiber optic, transmission cables from alternative energy projects, or other more recent cables in place. For the AOA suitability modeling, the cable data included is considered CUI, therefore the publicly available NOAA Charted Submarine Cables is presented here for visualization purposes.

Two ENC display services provide simple HTTP interfaces for user applications to request geo-registered nautical chart images from NOAA databases for display in online and offline applications for which a basemap of nautical chart data is desired, including GIS, web-based, and mobile mapping applications.

The chart images are rendered from the latest NOAA electronic navigational chart (NOAA ENC®) data. The ENC data and the chart images derived from it are updated weekly. Each display service portrays the ENC data with a different symbology set.

The ECDIS Display Service uses symbology developed by the International Hydrographic Organization (IHO) for the display of ENC data on Electronic Chart Display and Information Systems (ECDIS) that large ocean- going vessels and many smaller commercial ships use for navigation. This symbol set is commonly referred to by its IHO specification number, "S-52," or as "ECDIS symbology."

The ENC Viewer portrays ENC data using this ECDIS symbology.

Geometry shown for Shipping Fairways Lanes and Zones in Florida only. Shipping zones delineate activities and regulations for marine vessel traffic. Traffic lanes define specific traffic flow, while traffic separation zones assist opposing streams of marine traffic. Precautionary areas represent areas where ships must navigate with caution, and shipping safety fairways designate where artificial structures are prohibited. Recommended routes are predetermined routes for shipping adopted for reasons of safety. Areas to be avoided are within defined limits where navigation is particularly hazardous or it is exceptionally important to avoid casualties and should be avoided by all ships or certain classes of ships. Shipping Lanes and Regulations layer was created by extracting ENC (.000) files published by NOAAs Office of Coast Survey, Marine Chart Division (NOAA OCS). The web service was developed by CSDL/OCS/NOAA. Data will be refreshed weekly.
