Ship to shore

ADMIRALTY Vector Chart Service (AVCS) Online supports shore-based maritime decision making, such as vessel tracking, voyage planning and Accident and Emergency incidents; it is not to be used for navigation. AVCS Online users can have confidence in their decision making knowing they are using the same updated images of Electronic Navigational Charts (ENCs) that are used on board their ships, enabling maritime decisions to be made from ashore. 

Widest global maritime ENC coverage

AVCS Online provides access to images from over 16,000 ENCs available at all scales, just like AVCS used on board ships. 

Access world-leading global maritime ENC coverage from national hydrographic offices, following International Hydrographic Organization (IHO) industry S-52 standards. 

Display controls to replicate the on-board experience

AVCS Online provides chart display settings with similar functionality as ECDIS. The inclusion of pick reports enables you to select a feature for more information, replicating the on-board experience from ashore. 

Updated every week

As with AVCS used on board ships, AVCS Online is automatically updated every week, providing confidence that your decisions are made using images of the latest ENCs.

ADMIRALTY Information Overlay, unique extra nav​igational data

AVCS Online includes the ADMIRALTY Information Overlay (AIO),  providing additional passage planning information such as ADMIRALTY Temporary and Preliminary Notices to Mariners for paper charts, where they are not included in the underlying ENC. AIO also highlights navigationally significant differences between ENCs and ADMIRALTY paper charts.
