The professional electronic chart for the professional mariner

Professional+ is a global vector chart database that navigators have benefited from for years in the ECDIS and ECS systems. The chart sources are based on official charts (both paper charts and digital charts). The charts, produced by i4 Insight, should only be used as a navigational aid. This data however, facilitates the full functionality of an ECDIS, and is an excellent training choice for navigators before switching from paper to ENC.

To support safe navigation, Professional+ also contains additional information that is updated daily through our online updating service. For example, compatible ECDIS/ECS can display:

  • Worldwide temporary and preliminary notices – provides valid T&P NtMs published by Hydrographic Offices
  • service - helps mariners identify and avoid high-risk areas
  • C-Routes – automatic routing containing more than 6,200 ports

Supported Systems

Our SENC format is supported by the majority of ECDIS and ECS manufacturers.

The SENC format

The charts are converted by i4 Insight to SENC format type approved by DNV, preventing a time-consuming and risky data conversion on board. The main benefit of our SENC format is that installation and updating can be carried out in a fraction of the time compared to other formats. The worldwide database is distributed on one single DVD.


Professional+ is continuously updated by including new charts and new editions of charts and Notices to Mariners issued by the national Hydrographic Offices.

Depending on the customer's need, technical outfit and communication capacity, customers can choose from 3 different options to keep their onboard database updated. See our Licensing page. See our Download Status tab for the latest version list.


Professional+ products provide worldwide coverage in different scales divided into several levels. Dividing into zones and areas allows you to choose coverage based on your specific needs. See this graphically on our Zone Map tab.
