|used for waterways to build a unique object for each river|
|Tools for this tag|
The purpose of waterway relations is to have an object for each river. Common tags like references, wikipedia pages, and international names only need to be added once. However each segment should still have a tag name=* with the main name to describe the most common local name for each section.
|waterway||[river, stream, canal, drain, ditch]||Subtype of the waterway relation similar to waterway=* |
Hint: If the waterway starts as a stream and becomes larger, then use the tag of the largest waterway (e.g. river). This is purely informational, the stream members still need their own waterway=* tag.
|name||*||Name of the waterway |
The international name tags name:en=*, name:de=*, ... are recommended for large waterways. When a river gets multiple names (f.e. because it passes in multiple language regions), use all different names in the name tag, ordered from source to mouth, and split by hyphens. The individual sections can still get their localised name for that section.
