What is an Electronic Navigational Chart (ENC)? Electronic Navigational Charts (ENC), also known as digital vector nautical charts, are data sets to support all types of nautical navigation. An electronic navigational chart or ENC is an official database created by a national hydrographic office for use with an Electronic Chart Display and Information System (ECDIS). An electronic nautical chart must conform to standards stated in the International Hydrographic Organization (IHO) Publication S-57 before it can be certified as an ENC. Only ENCs can be used within ECDIS to meet the International Maritime Organization (IMO) performance standard for ECDIS. ENCs are available for wholesale distribution to chart agents and resellers from Regional Electronic Navigational Chart Centres (RENCs). The RENCs are not-for-profit organizations made up of ENC-producer countries. RENCs independently check each ENC submitted by the contributing countries to ensure that they conform to the relevant IHO standards. The RENCs also act collectively as one-stop wholesalers of most of the world's ENCs.
IHO Publication S-63 developed by the IHO Data Protection Scheme Working Group is used to encrypt and digitally sign ENC data. Chart data is captured based on standards stated in IHO Publication S-57, and is displayed according to a display standard set out in IHO Publication S-52 to ensure consistency of data rendering between different systems. IMO adopted compulsory carriage of ECDIS and ENCs on new high speed craft from 1 July 2010 and progressively for other craft from 2012 to 2018.

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

Sources and publication of Nautical Charts
A nautical chart is a graphic representation of a sea area and adjacent coastal regions. Depending on the scale of the chart, it may show depths of water and heights of land (topographic map), natural features of the seabed, details of the coastline, navigational hazards, locations of natural and human-made aids to navigation, information on tides and currents, local details of the Earth's magnetic field, and human-made structures such as harbours, buildings, and bridges. Nautical charts are essential tools for marine navigation; many countries require vessels, especially commercial ships, to carry them. Nautical charting may take the form of charts printed on paper (raster navigational charts) or computerized electronic navigational charts (ENCs). Recent technologies have made available paper charts which are printed "on demand" with cartographic data that has been downloaded to the commercial printing company as recently as the night before printing. With each daily download, critical data such as Local Notices to Mariners are added to the on-demand chart files so that these charts are up to date at the time of printing.
Nautical charts are based on hydrographic surveys. As surveying is laborious and time-consuming, hydrographic data for many areas of sea may be dated and are sometimes unreliable. Depths are measured in a variety of ways. Historically the sounding line was used. In modern times, echo sounding is used for measuring the seabed in the open sea. When measuring the safe depth of water over an entire obstruction, such as a shipwreck, the minimum depth is checked by sweeping the area with a length of horizontal wire. This ensures that difficult to find projections, such as masts, do not present a danger to vessels navigating over the obstruction.
Nautical charts are issued by power of the National Hydrographic Offices in many countries. These charts are considered "official" in contrast to those made by commercial publishers. Many hydrographic offices provide regular, sometimes weekly, manual updates of their charts through their sales agents. Individual hydrographic offices produce national chart series and international chart series. Coordinated by the International Hydrographic Organization, the international chart series is a worldwide system of charts ("INT" chart series), which is being developed with the goal of unifying as many chart systems as possible.
There are also commercially published charts, some of which may carry additional information of particular interest, e.g. for yacht skippers. (SOURCE: wikipedia - NAUTICAL CHARTS)

In addition to the ECDIS equipments used by large ocean-going vessels, ENCs (Electronic Navigation Charts) can also be used in a growing variety of electronic chart systems (ECS), chart plotters, and mobile devices by professional mariners and leisure craft owners alike
While the use of Digital Nautical Charts (ENCs) is increasing - use of Paper Nautical Charts is in dramatic decline...
ENC data is produced by many countries and used by mariners around the world. In addition to the ECDIS equipment used by large ocean-going vessels, ENCs can also be used in a growing variety of electronic chart systems (ECS), chart plotters, and mobile devices by professional mariners and leisure craft owners alike.
Use of ENCs also enables real-time vessel positioning and automated alarms or indications of unsafe conditions during voyage planning and while underway – safety features that paper charts cannot provide. The IHO has developed a new “S-101 ENC”7 that will eventually replace the “S-57 ENC” data currently used for navigation. The new ENC product specification enables interoperability with a growing family of maritime related products that comply with the IHO’s S-100 Universal Hydrographic Data Model. As hydrographic offices, including NOAA, start to produce S-101 format ENCs in the coming years, some systems will likely use the ENC as a “base map” over which other S-100 based products, such as marine protected areas, navigational warnings, surface currents, and other types of data, might be displayed. These are clear indications that ENCs are already an important part of the marine navigation “ecosystem” and will be even more so in the future.
Whilst ENC (electronic nautical charts) use is increasing, the use of traditional paper nautical charts is decreasing. Sales of NOAA paper nautical charts have dropped nearly 60% since 2010, sustaining a downward trend that started over two decades ago (see Figures below). The IHO Nautical Cartography Working Group documented similar declining sales of paper charts published by many other hydrographic offices around the world in their “Future of the Paper Nautical Chart Final Report”, released in August 2020.
(Stats figures by N.O.A.A.) - NOAA has distributed paper nautical charts exclusively through commercial print -on-demand partners since 2014. Sales of both lithographic and print-on-demand paper charts have been declining for over two decades as the sales stats above demonstrate. Guided by these trends, NOAA initiated a program to phase out its traditional paper nautical charts and their corresponding raster chart products and services
