OCPN Vector Charts are licensed and sourced from chart providers like Hydrographic Offices. These - non free - charts give OCPN access to up-to-date and proven charts for areas where those are not available for free.
The charts are delivered in an encrypted format optimized for OpenCPN and are requiring the corresponding oeSENC plug-in. They appear like all the other vector charts in S-57 format and can be quilted and managed identically.
Same as in the case of the S-63 plug-in, the operational part is managed by an outside entity, o-charts.org. The charts are available at its web shop.
Install the plug-in, enable it at Options | plug-ins and create your system identifier file from “Preferences” The plug-in will report the path to the file. For Windows and macOS systems a copy is created directly on the desktop.
The downloaded set contains a text file with information about the set, the license key, the EULA and the chart “blob” itself.
Each time you will use the charts from the set, a pop-up will inform you about the licensing period of the charts and you will have to accept the terms of use. These are requirements from our licensors.
One additional license for back-up purposes is included and can be generating by the user when required.
Until the solutions are in place we cannot recommend to use the combination W10/oeSENC.
