I found out today by reading the tagging that waterfalls are only points. I then fixed a waterfall that I'd tagged as a way. The waterfall at the mouth of Ogden Canyon (Ogden, Utah) is long enough that I had tagged it as a way. Should a proposal be made to be able to tag waterfalls this way?
Also, Niagara (for instance) is a wide waterfall. This should be tagged as a way as well, but with a different rendering.
- We tag various details of the waterfall by various means. The waterfall-edge is usually tagged as a cliff. The waterway=waterfall node should be at the intersection of the cliff and river, this node is there to be displayed as an icon. Look at the examples.
- There are various improvements that could be made but I would leave waterway=waterfall as node, has been around for a long time and do not want to break whatever is already working. The improvements which I see as more important are:
- mark the natural=cliff with an additional flag indicating it forms an waterfall edge which could then be rendered differently from normal cliffs in specialised renderers with a good enough fallback on standard rendering
- mark areas of water as "whitewater", not for rafting or kayaking purposes but to point out areas in the water which are generally very hazardous
- mark strong/fast currents in the water
