A4.2 Chart Subscription Service

A4.2.1 C-MAP service
There are three different services available through C-MAP Cartographic service that can be used in FURUNO
ECDIS FEA-2x07. Two of them are using CM-93/3 format. These data sets contain two databases:
CM-ENC (SENC delivery), Official Electronic Navigational Charts distributed by C-MAP on DVD.
Global Chart Database, which is available on CM93/3 professional CD-ROM. This database contains chart
data original produced both by C-Map and Hydrographic Office.
Global Chart Database, which is available on CM93/3 professional+ DVD. This database contains chart
data original produced both by C-Map and Hydrographic Office.
Note: CM-ENC is available. If you change CD-ROM service to DVD service, you need to also have a new license
for the DVD service. Contact your chart agent or C-MAP for details.
Additionally, the previous CM-93/2 Global Chart Database is compatible for use with the FEA-2x07.
A4.2.2 What is SENC delivery?
ENCs can be distributed as ENC delivery or SENC delivery. Both deliveries can be used in FEA-2x07.
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 charts are loaded into ECDIS. For more information, see section
8.6 "S57 Chart Service from an RENC"
In SENC delivery charts are converted from ENC to SENC before delivery to onboard and loading to ECDIS. A
CM-ENC delivery is SENC delivery.
Important notice!
If you are using both services (ENC and SENC deliveries) having the same chart name loaded into ECDIS 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 updates 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 ECDIS before loading charts from new
delivery.
When using any C-MAP chart, the indication "Non ENC Data" appears at the upper right corner on the ECDIS
display.
