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 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 459.
