Primar Vector charts

In addition to "Raster" charts (image of paper charts), ScanNav allows you to use S-57 vector charts , including Official(*) ENCs from SHOM and other Hydrographic Offices coded in S-63.

Vector charts allow you to query each element of the map for its details. You can for example display the light sectors on the map to know at a glance its range as well as each sector limits, or adapt the sounds according to the tide.

(*) The official ENCs consist in the origin surveys of Hydrographic Offices, unlike "private" vector maps that are reproduced manually by digitizing paper maps, or other sources. This therefore eliminates potential reproduction errors (see the SHOM article on the subject)

International Hydrographic Office Service Hydrographique et Océanographique de la Marine Directly issued by the Hydrographic Offices of the IHO member countries (SHOM for France), they are constantly updated. These updates are made available to users by download from Primar, on a weekly basis.
These are the only vector charts authorized to replace paper charts on merchant and military ships according to the SOLAS convention (Safeguarding human life at sea).

Detailed information on ENCs is available on the SHOM or IHO websites

ScanNav has been a Distributor of Primar (organization responsible for centralizing ENCs from different countries) since 2006, and was the first to introduce Official ENCS on the Leisure market.

We supply both yachtsmen from the Leisure market as well as large groups in the professional market. Thanks to our technical and commercial experience, we are able to provide you with expert support on the subject.
