An example (with part of the hydrography and nearly all of the landcover from non-OSM sources) follows. I'm rendering polygons of the river with a white overlay when they are stretches of rapids. The rapids can be short and relatively discrete as at https://kbk.is-a-geek.net/catskills/test4.html?la=43.3152&lo=-73.8440&z=15 In the mountains, though, there may be long stretches of nearly continuous whitewater: https://kbk.is-a-geek.net/catskills/test4.html?la=43.3604&lo=-74.3637&z=14 The last time I looked, there was no non-deprecated way to map the information that I had. I now see that @jeisenbe has restored the `waterway=rapids` tag to the Wiki. At the time I last had the discussion, the version of the page on the Wiki looked like https://wiki.openstreetmap.org/w/index.php?title=Tag:waterway%3Drapids&oldid=1322133 - deprecating the tag. On the other hand, the discussion on https://wiki.openstreetmap.org/wiki/Whitewater_sports is highly technical. I know that I am not skilled enough at whitewater paddling (I did a little in my youth, but my youth is quite a long time ago) to make a safe assessment of grade, and the `Whtiewater sports' page makes no mention of 'grade=unknown'. I asked here on the mailing list, and the only answers that I got were along the lines of "then don't map it." So for several years I haven't attempted to map rapids. The ones I know of and want to render, I maintain separately from OSM, because the previous discussion had caused me to label this feature mentally as, "OSM doesn't want this mapped." -- 73 de ke9tv/2, Kevin
