Ecdis licensing and updating of chart data and system software

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.

Most national institutions are members of the International Hydrographic Organization (IHO) which has developed a set of standards covering collection of chart data and production of charts.

It could be said that the development was one of many made possible by rapidly improving computer technology that had earlier allowed the introduction of automatic radar plotting aids (ARPA) on to the navigation bridge of commercial ships.

Initial systems were developed by individual manufacturers with little collaboration and to diverging standards as there was no performance standard to comply with.

Charts for use with ECDIS on SOLAS vessels must have been produced by a national hydrographic office using these standards.

With regard to ECDIS the most important of these standards are S-52 presentation library which contains all the symbols colours and lines styles required to recreate the ENC on the ECDIS screen and S-57 which includes a description of the data format, product specification for the production of ENC data, and an updating profile.

Despite there being no requirement to install the early systems onboard SOLAS vessels, several ship operators were willing to act as pioneering guinea pigs in the field.
