Admiralty Vector Chart Service (AVCS)

Taking you safely into the future of marine navigation, AVCS brings together electronic navigational charts (ENCs) from the UKHO and hydrographic offices. Please contact us for specific coverage & pricing.

AVCS Overview:

The Admiralty Vector Chart Service (AVCS) brings together Electronic Navigational Charts (ENCs) from national Hydrographic offices around the world and new ENC coverage produced by UKHO in co-operation with Foreign Governments to provide comprehensive, official, worldwide coverage.

Compliant:

AVCS contains only ENC data that meets SOLAS Carriage Requirements for use within Electronic Chart Display and Information Systems (ECDIS).

Quality:

AVCS meets customer requirements for a comprehensive, world-wide, full carriage compliant electronic chart service. AVCS continues to develop in response to customer feedback through an ongoing programme of enhancements. UKHO has instituted a programme of assessment by its professional cartographers where the content of the ENC is compared to relevant national paper charts. Any navigationally significant discrepancies identified are then investigated and resolved with the producing nation. No other electronic chart service offers this level of reassurance.

Carriage Compliant:

The Admiralty Vector Chart Service only contains ENC data that meets Safety of Life at Sea (SOLAS) Carriage Requirements for use within Electronic Chart Display and Information Systems (ECDIS).

ENCs:

Electronic Navigational Charts (ENCs) are digital vector charts produced to the International Hydrographic Organization's (IHO's) standards (S57 Version 3.1 and ENC Product Specification). They are referred to World Geodetic System 1984 Datum (WGS84) and are regularly updated with official update information distributed digitally.

Hydrographic offices do not take any responsibility for the accuracy or reliability of privately produced, unofficial charts.
