Subject: [OSM-newbies] Help -- How to use waterway=riverbank
Hello everyone,
I've been mapping the Little Colorado River, which, despite
its name, is rather large, bank to bank. When it's not encased in a
canyon--such as when it gets close to joining the big
Colorado--it's a typical Western U.S. river: a quarter-mile wide
and a foot deep. So, in the places where it is wide, I've been
mapping it as two riverbanks. However, it sometimes renders as a
large area of water, covering places that are not under water.
I know we are not supposed to map for rendering, but this
result makes me think that I am doing something wrong.
So, what is the correct way to handle
waterway=riverbank? Do we join the two banks from time to time (as
I have done to try to correct the problem)?
The area I have mapped is in northern Arizona, around the
towns of Cameron and Winslow.
Thanks in advance for your help.

Charlotte Just looking at
http://www.openstreetmap.org/edit?lat=35.87738&lon=-111.4111&zoom=17 .
To summarise the points which have been made already, and to add
some of my own.
Lets take, as an example, the bit of the river to the east of the
bridge in Cameron. This is currently made up of 4 ways (two long
ways of the real riverbank, and 2 which cross the river) .
You should either:
a) make all 4 ways into one way forming a closed area;
or b) add all 4 ways to a relation, each way with the role "outer"
and tag the relation with "type=multipolygon","waterway=riverbank",
"name=Little Colorado River".
In addition, ideally, there should also be a central way drawn in
the direction of the river flow, and tagged as "waterway=river"
Also where the river crosses under the bridge, the western part ,and
the eastern part should share the same small section of way, so that
the two areas butt up against each other rather than having the
short section of waterway=river between them( unless the river
really does narrow at that point).
David
