It's possible to estimate when a particular location on a river will be <br>
flooded based on the downstream (and to a lesser extent upstream) <br>
monitoring station level. Has anyone considered linking these together <br>
in any way? So far I've added a note on e.g. <br>
<a href="https://www.openstreetmap.org/way/37535250" rel="noreferrer" target="_blank">https://www.openstreetmap.org/way/37535250</a> to say "When <br>
<a href="https://www.openstreetmap.org/node/8373389773" rel="noreferrer" target="_blank">https://www.openstreetmap.org/node/8373389773</a> says 2.7m, flooded here", <br>
but some more formal way of saying that would make sense. I can happily <br>
invent something, but don't want to do that if an existing tagging <br>
already exists.<br></blockquote><div><br></div><div>This doesn't cover what you're proposing to do, but it may be worth taking</div><div>a look at and possibly collaborating with: <a href="https://riverlevels.uk/map">https://riverlevels.uk/map</a></div><div>It doesn't just have locations of monitoring stations, it shows their</div><div>current levels (it used to also show a graph of historical data but</div><div>that seems to have gone).
