Official ENCs
Primar Vector charts

maj: 24-01-2020


In addition to "raster" charts (issued from scan, such as Maptech), ScanNav supports S57 vector charts, including Official ENCs (*) from IHO, coded in S63 format.

In vector charts, each object is known as such, and ScanNav can query each of them to show their details. You can therefore show the sectors of a light to immediately visualize their angle and range.

(*) Official ENCs are the original survey of the hydrographic offices, contrarily to "private" vector charts that have been reproduced manually by digitalizing the paper charts. This therefore eliminates potential human errors in reproduction. (see article from SHOM on this subject)

International Hydrographic Office

Official ENCs (Electronic Navigation Charts) are the charts issued directly from the Hydrographic Offices of the countries member of the IHO (International Hydrographic Office, (SHOM for France)). They are the only vector charts authorized in replacement of paper charts on Commercial and Military ships, according to the SOLAS convention.

Detailed information on ENCs are available on the SHOM web site
or the IHO: http://www.iho.int

ScanNav is a distributor of Primar which is the organism responsible for centralizing ENCs of the different countries.
