What are ENC/S57?
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.

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. These are fully vectorised charts using the best available data for the area.

Are these 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).

Note:If used with a non-type apoproved ECDIS system then they do not meet carriage requirements..

Can I use S57/ENC data ?
Yes if you have an ECDIS system or any charting system that is able to use Electronic Navigational Charts (EMCs) this includes seaPro 3000.
