The ADMIRALTY ECDIS Service includes ENC data from:
The ENCs used in the ADMIRALTY ECDIS Service meet SOLAS chart carriage requirements when kept up-to-date and used within an ECDIS with suitable backup.
The Admiralty ECDIS Service is available in 36 regional folios as shown below. Each regional folios is available in these levels of coverage:
Transit - the ENCs and ARCS charts required for safe transit, including key ports of refuge and bunkerage ports.
Standard - the ENCs and ARCS charts required for operational use, including all key ports and approach charts.
Full - all available ENCs and ARCS charts.
Only one level of coverage should be purchased for each regional area.
Note: A small number of ENCs produced by Hydrographic Offices cannot be made available in the ECDIS Service.
Please contact us to get pricing for ECDIS Service coverage that will meet your needs.
The ADMIRALTY Information Overlay helps bridge crews identify areas of possible uncertainty and risk at the crucial passage planning stage. Displayed as a digital data set over charts, the overlay contains all Temporary & Preliminary Notices to Mariners (T&P NMs) and additional preliminary information that is specific to ENCs, such as reported navigational hazards that have been incorporated into paper charts.
The Overlay can be displayed on compatible ECDIS equipment and in ADMIRALTY e-Navigator Planning Station. An up to date list of compatible equipment can be found here. The ADMIRALTY YouTube Channel also contains a number of ECDIS specific installation Films that can guide you through installing and updating AIO. These can be accessed here.
How to use the ADMIRALTY Information Overlay
The Overlay is designed to be displayed on top of a standard ECDIS chart display and can be switched on and off without changing the underlying chart.
As the user zooms in or out, the ECDIS will automatically select charts of a suitable scale and the Overlay features relevant to that selected chart. For example, a Temporary NM that applies only to a large scale chart will not be displayed when smaller scale charts of the same area are being used.
T&P NMs - All ADMIRALTY T&P NMs that are in force are included in the Overlay. Each NM is displayed as a simple red polygon (usually rectangular) with red hatched fill which indicates the area affected by the NM. Each NM carries the same NM number that is used in the ADMIRALTY Notices to Mariners Bulletin.
The full text of the NM is included as an associated text file which can be displayed by selecting the 'Temporary Notice to Mariners' or 'Preliminary Notice to Mariners' feature in the ECDIS Pick Report. Any associated diagrams can also be viewed through the Pick Report.
EP NMs - ENC P (EP) NMs contain additional information that is specific to ENCs and cannot be published as a standard ADMIRALTY T&P NM. These NMs are displayed in the same way as T&P NMs, as a simple red polygon (usually rectangular) with red hatched fill which indicates the area affected by the NM. Each NM is allocated a unique EP NM number.
The full text of the NM can be viewed in the ECDIS Pick Report against the Information attribute. Where additional information is needed to explain the NM an associated picture file displays an image showing the ENC superimposed over the current paper chart information.
Compatible Display Systems
All type approved ECDIS (Electronic Chart Display and Information Systems) and many unofficial ECS (Electronic Chart Systems) are compatible with the Admiralty ECDIS Service.
Due to the growth in the number of ENCs (Electronic Navigational Charts) available worldwide, some older ECDIS suffer from performance issue when installing Admiralty ECDIS Service. Please consult your equipment manufacturer if your ECDIS was installed before January 2009.
