@anderslund Would using S-101 maybe help with this as it has the styles available as well (and is the next-gen)? I have to admit I haven't looked into actual S-57 or S-101, but have looked into S-124 (navigational warnings) and S-421 (route exchange) quite a bit and have written a plugin for QGis to display S-421 (version 2 that is to be released) routes according to the portrayal catalog (without taking into account turn radius' etc).

@anderslund Yes they do. But it's interesting to look at this project and at the same time follow the discussions of device manufacturers and how they see things.

@anderslund Just out of interest, have you looked into the S-100 portrayal catalogue for the styles that are used there?

Because then the visualisation would be exactly the same as on official navigation equipment (ECDIS etc). Just a thought as there a lot of the symbology would already exist (svg:s etc) but then also colors etc that suit exisiting charts.
