[OSM-newbies] Help -- How to use waterway=riverbank

[Dave F.]

  Hi Charlotte

This page may help:

http://wiki.openstreetmap.org/wiki/Tag:waterway%3Driverbank

As it says you should still include a way tagged as waterway=river to 
indicate the flow direction. This can be changed in Potlatch if 
necessary by selecting the way & clicking the arrow icon in the bottom 
left of the screen.
On this way I also include a width=* to suggest the width of the river, 
but as this is rendered, if this isn't accurate & not dead centre of the 
riverbanks it may overlap with them.

As you suggest, it's best to divide it up into smaller sections. I try 
to place them next to river crossing, but as yours is very wide that's 
probably doesn't occur very often.

Often it helps to send a permalink (bottom right of the webpage map) of 
the area your working in so the others can take a look.

Hope that helps

Dave F.
