AVCS - Admiralty Vector Chart Service

The Admiralty Vector Chart Service (AVCS) brings together Electronic Navigational Charts (ENCs) from HOs around the world with new ENCs produced by UKHO in co-operation with foreign governments to provide the most comprehensive, official, worldwide nautical chart coverage available.


Quality Controlled 

The UKHO has instituted a programme of assessment by its professional cartographers to compare the content of ENCs to the relevant national paper charts. Any navigationally significant discrepancies identified are then investigated and resolved with the producing nation. No other electronic chart service in the World offers this level of reassurance.

Carriage Compliant

AVCS only contains ENCs that meet 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.
