perhaps you followed the S-63 thread in this forum. This project
is underway in order to give OpenCPN users access to official vector charts - the S-57 charts in the encrypted S-63 distribution format like those prduced by kartverket and distributed by PRIMAR.
We made progress and the technical skeleton is in place.
OpenCPN in this moment is an OEM manufacturer of the IHO and has the right of using S-63 charts legally.
We are working now on the user interface and the organisational parts
One part will be a Webshop, where the UserPermits will be issued and where the user shall access to charts.
So the webshop will be in place in not a too far time. We just have to fill it.
Don't expect gratis charts. This is a political decision of the Hydrographic offices (and the governments they belong to) have taken and the actual policy of "austerity" does not help to change this posture.
Nethertheless there is a clear consciousness at the distributors and the Hydrographic offices that theie business model is not satifsying the leisure seafarer. They are focussed on comercial shipping
and infrastructures, including military usage of course.
We would be happy to discuss with kartverket if they see a possibilty to deliver differentiated chart packs to OpenCPN users. OpenCPN we be able to handle this.
