The default render should be with connectors below the water bodies. AKA render issue. Possibly there should be some way to force it to render on top, and that would probably need a new tag. The main reason would be to show the navigation route if it is restricted or complicated. Shallow water with a canal, or large complicated reservoir would be 2 examples. This should also be discussed with the openseamap people since it is primary for water navigation and they have the knowledge to give the best input.
I agree using the oneway tag is the wrong approach to show flow direction. Perhaps a flow or current tag. If we want to show that, I think that should also have a separate tag. Basically duplicating the way oneway works. The downside is this would complicate editing and displaying if it was tagged with both. That said, for now using oneway is better than not tagging flow direction. -- Dale Puch On Fri, Feb 18, 2011 at 3:53 PM, Mike N <nice...@att.net> wrote: > On 2/18/2011 3:43 PM, Paul Norman wrote: > >> Here in Canada with the NHN import the portion of streams through lakes >> and >> wider rivers were imported with sub_sea=stream sub_sea:type=inferred >> oneway=yes >> > > There is some disagreement about using oneway=yes, presumably to match the > stream flow.
