Hi Andy<div><br></div><div>Interesting problem - in some cases I use tunnel=yes and layer=-1 where it's a short section and likely to be straight. Where it's a longer underground section I just tag waterway= stream:underground ( or something similar) so that the data is there but there's no render. Two reasons - stopping clutter on the rendered map and also we can't be sure of the route</div>
<div><br></div><div>Relation - too much work for a dubious return - a name tag on each visible(rendered)section works just as well</div><div><br></div><div>Regards</div><div><br></div><div>Brian<br><br><div class="gmail_quote">

I've just added some sections of Hockley Brook:<br>

as straight lines, tagged as pipes, with level -2, where it disappears<br>
underground. Is there a better way to tag such things?<br>
<br>
I'm working backwards (upstream) from its confluence with the Tame at<br>
Spaghetti Junction, so if anyone knows its route west of what I've<br>
done so far, please feel free to chip in.<br>
<br>
I've also made a relation for it; the first time I've ever done one,<br>
so please feel free to make constructive criticism.<br>
