142:(IMO) have begun a transition to a new suite of standards that is targeted to exist as a unified, interactive suite of products and standards within the S-100 Universal Hydrographic Data Model. Within this model an updated standard for the production and publishing of ENCs is under development; The S-101 product specification. At present Hydrographic Authorities must only produce and publish data to the S-57 product specification, from here that published data can be certified as an ENC. Only ENCs can be used within ECDIS to meet the

In the future, the ENC will be part of a product specification family which is based on the "IHO Universal
Hydrographic Data Model", known as S-100. The product specification number S-101 has been assigned to the ENC. ENCs are now being produced under the S-100 standard and it is envisaged that S-100

ECDIS (as defined by IHO Publications S-57 and S-52) is an approved marine navigational chart and information system, which is accepted as complying with the conventional paper charts required by
Regulation V/19 of the 1974 IMO SOLAS Convention. as amended. The performance requirements for ECDIS are

The term "ENC" typically refers to "Electronic
Navigational Chart," which is a standardized format used for digital navigation charts. While there are variations and different specifications within ENC charts, they generally serve similar purposes across different regions and organizations. Here are

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

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

Overlay ENC charts are used to provide additional layers of information over a base ENC. They may include thematic overlays such as environmental data, fishing zones, or military exercise areas, allowing mariners to overlay different types of information on a single chart display. These categories

Route ENC charts are used for planning and navigating specific routes, such as ferry routes, shipping lanes, or other designated passages. They may include additional information relevant to the designated route, such as traffic separation schemes or recommended tracks. Overlay ENC (OVL-ENC):

ENCs will replace S-57 data sets by the 2030s. The new ENC standards include greater data layers allowing for enhanced navigation formats, such as S-129 on Under Keel

Regional ENC charts cover specific geographic regions and are tailored to the needs of vessels operating within those areas. They may include localized navigation aids, safety information, and specific hydrographic data relevant to the region. Port ENC (P-ENC):

Official ENC charts are those that are officially produced and maintained by national hydrographic offices or other authorized agencies. They are updated regularly to reflect the latest survey data and navigational information. Base ENC (B-ENC):

Port ENC charts focus specifically on harbor and port areas. They provide detailed information on berthing facilities, channels, depths, and other navigational aids within ports to aid safe navigation and maneuvering. Route ENC (RTE-ENC):

ECDIS provides continuous position and navigational safety information. The system generates audible and/or visual alarms when the vessel is in proximity to navigational hazards. Military versions of ECDIS are known as
