In response to your feedback, we have made new changes to our AVCS Online service to better meet our customers’ needs for shore-based, non-navigational decision making. Find out more about AVCS Online and how it can benefit your navigational planning experience.

What is AVCS Online?


AVCS Online is a shore-based viewing service of the official ADMIRALTY Vector Chart Service (AVCS) – the world’s leading maritime chart service used on board most ships trading internationally.

AVCS Online has been created to use as an aid to navigation, supporting shore-based maritime decision making, including tasks such as vessel tracking, voyage planning and accident and emergency incidents. It provides access to images of over 18,000 fully up-to-date Electronic Navigational Charts (ENCs) – the widest coverage available. This includes all available scales and coverage of 4,000 of the largest ports worldwide.

To replicate the experience of using an Electronic Chart and Display Information System (ECDIS), AVCS Online also offers full control over layers with display controls and pick reports. .

Shore-based planning with confidence

AVCS Online is offered as an online viewing service to help you make planning decisions with confidence. By accessing images of AVCS ENCs from your web browser, you can see exactly what your crews are seeing on the ECDIS on board their vessel - enabling harmonised, seamless decision making between ship and shore.

Bringing the benefits of AVCS to shore-based crews

Bring the benefits of AVCS from ship to shore, with world-leading coverage compiled from national hydrographic offices across the globe, using official standards set by the International Hydrographic Organization (IHO).

By using official ADMIRALTY ENCs for shore-based support (instead of unofficial alternatives) this will help safeguard Safety of Life at Sea (SOLAS) navigation for your crews.

Offering images of the latest ENCs

Through AVCS Online, you can access images of the latest ENCs, without the need for any manual updating. While these cannot be used for on-board navigation or route checking, AVCS Online offers images of the same carriage-compliant ENCs available in AVCS  to support safety of life at sea. These can be used as an effective aid to navigation to support shore-based maritime decisions, to enable shared decision making between ship and shore.


ADMIRALTY Information Overlay

AVCS Online includes the ADMIRALTY Information Overlay (AIO), providing additional passage planning information such as ADMIRALTY Temporary and Preliminary Notices to Mariners (T&P NMs) in a clear overlay.
