Seamark Attribute Index

This index lists the items in the S-57 & S-101 Attribute catalogues and their OSM tag names.

Each attribute has links to the page that (hopefully) describes the tagging of the objects that use that attribute. For unclear or missing tag instructions, the underlying tagging schema is described at Seamark Tagging Schema.

A similar index of S-57/S-101 objects that use these attributes is at Seamark Objects
