S57 chart managing with C-MAP charts
Licence system used by the C-MAP
The licence system with C-MAP is based on serial numbered CD-ROMs and Authorisation Codes received from C-
MAP Norway A/S. You select either required C-MAP Areas or Zones and your Electronic Chart System generates
an User Code based on your selection, the serial number of the serial numbered C-MAP CD-ROM and the Hardware
Identifier of your Electronic Chart System. You send the User Code to C-MAP Norway A/S and they send to you an
Authorisation Code. You enter the received authorisation code into the system and then you can load and convert
the CM-93 charts into your system.
How to get started with C-MAP charts
1. Select automatic conversion into the SENC and setting of Display and Approve Update dates
automatically. See "How to make conversion into SENC and set display date automatically
with C-MAP charts" on page 453.
2. Define your subscription of C-MAP charts. See "How to define subscription of C-MAP charts"
on page 439.
3. Load C-MAP charts by CD catalog. See "How to load C-MAP charts from a CD into the
system" on page 444.
How to keep up to date your C-MAP charts
At regular intervals C-MAP will reissue its charts to keep them up-to-date. There are neither edition number nor
update number in C-MAP charts, so the system recognises changed charts using issue date of the chart.
The procedure of loading the reissue is the same as loading of the C-MAP charts first time. If loaded chart is already
in the hard disk with older issue date, the system loads selected newer chart automatically. Other possible messages
when loading C-MAP charts are explained in the end of the chapter "How to load C-MAP charts from a CD into the
system" on page 444.
If you get a new release of a C-MAP CD-ROM, proceed as follow:
1. Select automatic conversion into the SENC and setting of Display and Approve Update dates
automatically. See "How to make conversion into SENC and set display date automatically
with C-MAP charts" on page 453.
2. Load C-MAP charts by CD catalog. See "How to load C-MAP charts from a CD into the
system" on page 444.
