[talk-au] How to tag reaches (segments of a waterway)?
I would like to map some named reaches (straight portion of a stream or river, as from one turn to another;) part of a major river. The river (e.g. http://www.openstreetmap.org/?lat=-33.50134lon=150.8778zoom=15layers=M ) currently has both a riverbank area drawn, and a way down the middle of the river. To make things even more complicated, the way running down the middle of the river has both waterway tags and administrative boundary tags. I'm thinking the ideal way to map this (reaches + river + admin boundary) would be split the way into segments for each reach, tag each segment as waterway=reach, name=Foo Reach, then collect up the river segments into a relation which contains waterway=river, name=Bar River, and just leave the riverbank area as is. Not sure what to do with the admin boundary tags though. I'm not sure what's best though. Any thoughts? Thanks. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

Re: [talk-au] How to tag reaches (segments of a waterway)?
The historical map I'm getting the information from calls them ... Reach. According to http://en.wikipedia.org/wiki/Reach_%28geography%29 Most generally, a reach is any length of a stream between any two points. I can't think of a better term myself, so unless there are any other suggestions I'll use reach for the time being.

Re: [talk-au] How to tag reaches (segments of a waterway)?
Hi, 'linear network water flow' should suffice. ... it's been recommended to tag it as 'directional=yes' where it's just a line in the direction of the water. .. if it's unknown 'directional=unknown'. You could put 'oneway=yes' but don't let the talk-ca list know about it as some people will get all excited about it. ... it'll just add a nice arrow across the river, and make it look good. cheers, sam On 4/9/11, Andrew Harvey andrew.harv...@gmail.com wrote: The historical map I'm getting the information from calls them ...

Agree and include the river banks as part of the relation. Leave all the admin boundary out of it and remove any waterway tags from the admin boundary. You should not need the river way down the middle if the river banks have been mapped. Cheers Ross ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

You should not need the river way down the middle if the river banks have been mapped. Bearing in mind reach is also the nautical term for a tack, is it worth considering Andrew's source map might be documenting the lines of sailing between navigation markers (or indeed landmarks) which are no longer even well-known? [Disclaimer: I-am-not-a-sailor.] They may not even document current-day navigation channels, if that part of the river required dredging to keep such open in the past. In other words I am wondering whether it might be best to add the new names completely independently of both the waterway and the administrative boundary. Maybe create a tag like waterway:navigation, perhaps for the new feature, perhaps? Justification for independence: these things are straight segments which rationalise a natural (i.e. curved) waterway for boating purposes... therefore are not the waterway itself. Similar argument for them not being the administrative layer (although they might be - can this be checked in any way?)

My 2c.
Stuck in my mind is Madmen's Bend at Hay, which refers to a part of
the river, and it is not a /reach/, but also warrants its name
recording as the sign nearby is recording the name.

Have we got some other word for the smaller part of the waterway?
