searching for tag waterway:sign i have found CEVNI Notice Marks used in European Inland Waterways

maybe use these tags in replacement of one from Freitonne

Yes, for now, as principle, let's stay the closer possible to OpenSeaMap when it makes sense.

[yohanboniface]

I suggest to display them only at zoom 18, what do you think?

[yohanboniface]

Humm, in Chalon-sur-Saône, I see a "no_u_turn" sign, which is not is the CEVNI list. Do you think it's "no_turning"?

[ClaudeMa]

yes it is "no_turning" in freitonne extention the vale is "no_u_turn"
ok for rebdering at zoom 18

@ClaudeMa I've pushed a first version, but it appears that the values we have in db do not fit the icons names of the CEVNI list. Do you know a way to get the mapping between both?

Damn, it seems that OpenSeaMap uses seamark:* and not waterway:sign.
I'm not really big fan of the idea of using seamark as a generic tag, but I think we have to stay close to OpenSeaMap to help the OSM database and usages keep consistent.
seamark:type = 107.099 nodes (http://taginfo.openstreetmap.org/keys/seamark%3Atype)
waterway:sign = 8.215 nodes (http://taginfo.openstreetmap.org/keys/?key=waterway:sign

• ft_symbol = 1 747 nodes (http://taginfo.openstreetmap.org/keys/ft_symbol#overview)
• seamark:type = 127 737 objects (http://taginfo.openstreetmap.org/keys/seamark%3Atype)
• waterway:sign = 9 244 (http://taginfo.openstreetmap.org/keys/?key=waterway:sign)
• List of Freitonne symbols (with OSM tags)

using OpenSeaMap's transparent seamark tiles as an overlay makes more sense to me!
