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.

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.

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, 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.

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 provide an accurate high-resolution shoreline compiled from imagery of PORT OF WILMINGTON, NC . This vector shoreline data is based on an office interpretation of imagery that may be suitable as a geographic information system (GIS) data layer. This metadata describes information for both the line and point shapefiles. The NGS attribution scheme 'Coastal Cartographic Object Attribute Source Table (C-COAST)' was developed to conform the attribution of various sources of shoreline data into one attribution catalog. C-COAST is not a recognized standard, but was influenced by the International Hydrographic Organization's S-57 Object-Attribute standard so the data would be more accurately translated into S-57.

Spatial information on the arrangement of geological features, habitats and living marine resources on the seabed are often the foundation for decision-making in ecosystem management and ocean planning. Collecting information on the seabed depths and geomorphology is an expensive operation requiring airborne platforms like satellites, planes or drones, or small vessels to large research ships. Coordinating these data needs and data collection efforts will better leverage collective resources and meet shared goals. To help enable this coordination, in 2020 the National Oceanic and Atmospheric Administration (NOAA) National Centers for Coastal Ocean Science (NCCOS) developed a spatial framework, process, and online application to identify common data collection priorities for seafloor mapping, sampling, and visual surveys along shore and offshore of the Southeast United States (North Carolina, South Carolina, and Georgia). Twenty-five representatives from federal and state agencies, academic institutions, and non-governmental conservation groups, designated seafloor mapping priorities using an online prioritization tool. Participants allocated virtual coins across 5 km x 5 km grid cells to denote their organization’s regions of seafloor mapping needs. Grid cells with more coins were higher priorities than cells with fewer coins. Participants also reported why these locations were important and what data types were needed. Results were analyzed and mapped using statistical techniques to identify significant relationships between priorities, reasons for those priorities and data needs. These data are the summarized results from this project and can also be viewed in an online web map (https://noaa.maps.arcgis.com/apps/webappviewer/index.html?id=04cdd2a68c4f427f893f2042f326dc80). Several common areas of interest were identified in the spatially explicit analysis of the responses. Nearshore surfzone along Georgia, South Carolina, and North Carolina were highlighted by several agencies and organizations interested in sediment and sand resources as well as potential for rocky reef habitats. Inshore estuarine areas were highlighted by state agencies and conservation groups interested in monitoring change in managed areas like National Estuarine Reserves. On the outer continental shelf, areas near Blake Plateau off South Carolina and the continental shelf break off North Carolina were identified by federal agencies and conservation organizations as areas of sensitive habitats or historically significantly shipwrecks and maritime resources. The seafloor mapping prioritization approach described in the Buckel et al. (2021) report associated with these data provides recommendations to organizations charged with mapping the seabed for navigation and commerce as well as resource assessments and management. Already, the priority areas identified in this exercise are being used by NOAA to focus planned seafloor mapping missions. Furthermore, the outcomes from this regional exercise contribute into a National Mapping Prioritization under the lead of NOAA to coordinate mapping activities across the entire US EEZ. Together, these quantitative seafloor mapping prioritization approaches will enable improved coordination and more efficient allocation of resources needed to conduct seafloor mapping providing data to support environmental stewardship, safe navigation and commerce.
