C-MAP vector format
The C-MAP charts require a contract with applicable provider. There are two types of
C-MAP charts; C-MAP ENC SERVICE, which are officially recognized charts, and C-
MAP PROFE, which are charts from a private source and cannot be used
as a substitute for paper charts under any condition. To emphasize this point these
charts are called "Non-ENC" charts in this manual.
Note: Some eToken dongles from the FEA-2xx7 can be used with this system. These
are labeled "JeT FURUNO XXXXX". Contact your dealer for details.
This ECDIS accepts the following C-MAP chart types: ENC SERVICE, PROFES-
, ENC+ SERVICE and ADMIRALTY ENC SERVICE.
C-MAP ENC SERVICE charts comply with the IHO's (International Hydrographic Or-
ganization's) S-57 Edition 3 product specification. When used in the chart radar, the
ENC data improves the safety of navigation at sea. When used in an ECDIS, the ENC
data improves the safety of navigation at sea.
What is ENC delivery?
ENCs can be distributed as ENC delivery or SENC delivery. Both deliveries can be
used in this system.
In ENC delivery, charts are distributed directly from source like PRIMAR, IC-ENC,
JHA, etc. They are delivered onboard in ENC format (using S-57 and S-63) then the
charts are installed into the system.
In SENC delivery, charts are already converted SENC before delivery and then in-
stalled into the system. A C-MAP ENC delivery is SENC delivery.
Important notices on ENC delivery
• If you are using both services (ENC and SENC deliveries) having the same chart
name installed into the system through both deliveries, priority of displaying the
chart is in ENC delivery.
• Chart updates for ENC delivery are only for charts of ENC delivery and chart up-
dates for SENC delivery is only for charts of SENC delivery. You have to keep
charts up-to-date separately.
• If you change from ENC delivery to SENC delivery, remove old charts from the sys-
tem before installing charts from new delivery.
