UKHO launches Admiralty Information Overlay

The Overlay brings the convenience and completeness of Admiralty paper charts into digital navigation.

It includes all Temporary and Preliminary Notices to Mariners (T&P NMs) and provides additional navigationally-significant information from UKHO’s electronic navigational chart (ENC) validation programme.

The Overlay is displayed as a single layer on top of the basic ENC. It will be available free of charge as part of the Admiralty Vector Chart Service (AVCS) and within Admiralty Value Added Resellers’ services.

The Hydrographic Office says that it has developed the new Overlay to give seafarers an easy way to view the information they need - in addition to the standard chart - to navigate safely and compliantly. It should make passage planning simpler and safer by clearly showing where important Temporary or Preliminary changes may impact a voyage.

It will also give seafarers the same consistent picture of the maritime environment on their Electronic Chart Display and Information System (ECDIS) as they have always had with the Admiralty paper chart.

UKHO is working with major ECDIS manufacturers to ensure that the Overlay can be displayed on their systems - Transas is the first to announce compatibility, with others expected to follow soon.
