<div dir="ltr">With overpass you can find all objects that have certain tags, e.g. <a href="http://overpass-turbo.eu/s/4F2">http://overpass-turbo.eu/s/4F2</a> finds all administrative boundaries without wikidata tag.<div>By default Overpass Turbo renders those areas in yellow with a blue border.</div>
<div><br>I have not experimented with overpass + mapcss, but <a href="http://wiki.openstreetmap.org/wiki/Overpass_turbo/MapCSS">http://wiki.openstreetmap.org/wiki/Overpass_turbo/MapCSS</a> should give an idea of the possibilities.</div>

Hi,<br>
<br>
It's a well known fact that many people complain to tag in vain
because what they tag doesn't show on the map (e.g. mini-golf vs
tennis pitch), because they're told to open a rendering ticket
which replies that only official tags are supported, and because
they open a vote for an official tag and nobody signs.<br>
As a result they are accused of "tagging for the renderer" instead
of "being forced to tag for the renderer".<br>
<br>
The solution is simple however. A RENDER tag that, typically,
would assign a color to an area.<br>
I'll let the rendering specialists define what else it can do.<br>
<big><big>⚠ ⚠ ⚠ </big></big> RENDER only requests <b>by default</b>
rendering.<br>
As soon as rendering is defined for an element, it is used instead
and RENDER is normally ignored.<br>
</blockquote>
I summarize the answers below.<br>
An example for using RENDER is this:<br>
<b><br>
landuse=recreation_ground</b> a sort of holiday/family event site
inside which you have<br>
a quite visible <b>leisure=pitch sport=tennis</b><br>
and two perfectly invisible polygon features (official tags or so),
hence to which we add RENDER:<br>
<b>leisure=miniature_golf</b> render=coral<br>
<b>landuse=boat_storage sport=kayak</b> render=darkblue<br>
<br>
As usual, every other reply I received disparaged this suggestion
without proposing the slightest alternative, for example only force
drawing the outline without color (that would do if a name can be
inside).<br>
<br>
Hence, the general consensus is either to tag for the renderer or
not to tag such touristic POIs at all.<br>
It's strange to have to campaign for tagging !!!<br>

Interesting, Marc.<br>
Could you please elaborate, explain how to use overpass and css and
show the resulting tagging for example for the above case?<span class="HOEnZb"><font color="#888888"><br>
