Seamark tagging

This is the index of the items in the S-57 & S-101 Object catalogues and their OSM tag names. Each object has links to the page that describes the tagging of that particular object.

An additional overview for the selection of S-101 categories of objects can be found here: seamark categories of objects(en).

The complete index of S-101 attributes for the objects is at: seamark attributes.

Data on current object usage: seamark object usage

Object index

The value of the seamark:type=* tag is the object type and can be used in seamark:<object type>:<attribute> tags.
