ARCS Charts are digital versions of the Standard Paper Chart and are available  individually or in folios as shown  in the diagram Folios can be ordered  as Full,  Standard or  Transit. The license period is one year.

Electronic Navigation Charts (ENC’s) are produced by the Hydrographic Offices of a number  of Countries and also  by  private Companies.  Only ARCS charts and ENC’s produced  by National Hydrographic  Offices to the  standard  required  by the International Hydrographic Office are considered  as ‘Official’  ENC’s and accepted for primary  navigation when  Flag State requirements  are also complied with.

The Electronic Chart Display and Information System (ECDIS), installed on board, processes the ENC Data for navigation and in modern vessels  and forms part of an integrated control and information console.  The ENC’s can  also be  used  on  personal (back of Bridge)Computers or PC’s using a compatible Navigation Program.

Requirements-Sufficient official data adequate for the intended passage are installed on the ECDIS. A second type approved  ECDIS  is installed as a backup (or there is a full paper chart backup)

The UKHO is the major producer and supplier of  ARCS and ENC’S for use in modern navigation systems such as ECDIS.

With all Admiralty  Electronic charts/digital products, users have to be  registered. It is a relatively simple Process requiring details of the user.Computer equipment, and the Program being used to display. The Charts/ENCs must be compatible. The first electronic  ‘officially’ recognised charts produced were the  Admiralty Raster Chart System (ARCS).

Please contact us - ‘The Tyneside’  by phone  - email or  Fax for any additional information.
