Chart - C-Map | PC Maritime's partnership with UK Hydrographic Office
Marine Software and Electronic Charts



CAES is the new C-Map partnership with the UK Hydrographic Office. CAES are official S-57 ENC charts supplied by Hydrographic Offices and pre-compiled into C-Map’s type-approved SENC format. SENC format delivers the charts in ready-to-run format, which speeds up and simplifies installation of charts and updates. CM-ENCs meet ECDIS regulations and provide Real Time Updating via email, internet or on DVD.


The C-Map ENC+ Service, a cooperation between C-Map and the Norwegian Hydrographic Service, combines Electronic Navigational Charts (ENCs) from Primar and CM-ENCs to give global ENC coverage from one source. The service ensures that mariners are always navigating with an approved ENC from hydrographic offices, when these are available. If an ENC is not available for any area, the service will notify the navigator (during route planning or navigation) and add in C-Map Professional+ chart data. 

Weekly updating is included in the annual licensing costs.


These are vector charts for commercial navigation, distributed in the CM93/3 format. The Professional+ service is supplied on DVD – you need to check whether your navigation system can accept DVDs. Professional+ can be used in combination with C-Map official ENCs, a concept known as ‘Dual Fuel’. This gives you vector chart coverage in areas not covered by ENC.


There are three different options to keep updated with new charts, new editions and Notice to Mariner updates:

– C-Map Update Service on DVD
– C-Map Update Service Online
– C-Map Update Service Online+
