<p>We have a hierarchy of "importance" for roads, why not for waterways as well? It's like we have nothing between motorway (river) and unclassified (stream).</p>
<p>The problem I see with some of these stream models is that we are starting from the big rivers with no mapping of tributaries in many cases. As detail gets added, it looks like the ratings of all the downstream segments will need to be recomputed. If there is a system that starts with a "1" for the estuary and uses increasing values as you go upstream and pass confluences, that would minimise the recomputations required.</p>

<br /> What's the problem with intermittent flows? I'm not familiar with water<br /> tagging.<br /> <br /> River width is a local property - it can vary lot in different places.

<br /> The width is fine for many small rivers where mapping riverbanks would be<br /> a nonsense and should be respected by the renderer.<br /> But what you ask for seems like tagging for the renderer. Most of the <br /> information is already there, either river width or the geometry determined <br /> by riverbanks.<br /> <br /> Richard<br /> <br /> _______________________________________________<br /> Tagging mailing list<br /> <a href="mailto:Tagging@openstreetmap.org">Tagging@openstreetmap.org</a><br /> <a href="https://lists.openstreetmap.org/listinfo/tagging">https://lists.openstreetmap.org/listinfo/tagging</a></div>
