Digital charts and publications


ADMIRALTY Digital Charts

The Admiralty digital chart service offers the world’s most complete official maritime chart coverage. The digital charts can be supplied in two distinct formats.


The ADMIRALTY raster chart service uses the same imagery and symbols as found on the Admiralty Standard Navigation charts, thus providing the mariner with a familiar feel to the traditional paper charts. This, combined with accurate satellite positioning provided by an electronic chart system (ECS) or ECDIS navigation system, can provide the mariner with situational awareness and a tool to better understand critical information when most required.

Weekly updates, provided either via CD or the internet, ensure that the mariner or shore-based company has access to complete and up-to-date information. Having the updates loaded electronically saves time and reduces the chances of errors that can occur with the manual updating of paper charts.

The ARCS charts can be licensed on a chart-by-chart basis thereby providing flexibility in your ordering of charts as you only license what you need!

The ADMIRALTY Vector Chart Service (AVCS) is the most comprehensive, official, digital maritime chart service in the world; with over 13,800 Electronic Navigational Charts (ENCs) from hydrographic offices around the world, packaged and quality assured by the UKHO into a single value-added service.

The most comprehensive global coverage available

AVCS provides the most extensive official coverage, allowing ships to navigate on ECDIS for the entirety of most major routes on a single chart service. This coverage includes 4,000 of the biggest and busiest ports worldwide, of which we offer unique coverage for over 150.

100% official, certification provided

All ENCs in AVCS meet the mandatory chart carriage requirements of SOLAS Chapter V, with certificates provided for local inspection.

All AVCS customers will also receive weekly ENC updates by internet download, email, or disc. Installing the latest updates on a regular basis supports safe navigation and compliance with flag and port state requirements.

Operates on all ECDIS makes

AVCS is delivered in industry standard S-63 / S57 formats, guaranteeing compatibility with all ECDIS sold today – even in a mixed fleet.

AVCS S-63 Edition 1.1 also meets the latest authorized data protection standard from the International Hydrographic Organization (IHO), designed to reduce the risk of both data piracy and the distribution of unofficial, dangerous ENCs to the mariner.

Free unique ADMIRALTY Information Overlay feature

To help bridge crews recognize areas of possible navigational vagueness and risk at the crucial passage planning stage, all AVCS customers receive the unique ADMIRALTY Information Overlay (AIO) at no extra cost. Combining all UKHO Temporary and Preliminary Notices to Mariners (T&P NMs) for all ADMIRALTY Standard Nautical Charts, and ENC Preliminary Notice to Mariners (EP NMs), AIO is displayed as a single layer on top of an ENC.
