Tags for Nautical Chart Features
The following is a list of valid keys and values of tags used for nautical charts. Only tags with these keys will be interpreted by the various nautical chart renderers.
The tags described in these pages may be placed on any node, way (open or closed) or multi-polygon. The direction of ways making up a multi-polygon, either inners or outers, is not important. Only relations with at least one member with role outer and whose outer members form at least one closed area can be processed.
All tag keys and values are based on elements defined in the object and attribute catalogues of IHO S-100. The six-letter mnemonics used in that standard have been replaced by words or underscore separated English phrases for human readability. The format of tags is described in Seamark tagging schema.
