charger location and a multi-charger location is a place
where you could charge your vehicle, and the proposal is to
map them the same way. This is similar to a fuel station,
where I would tag one single pump, typically at a rural
location, as amenity=fuel. <br></div></div></div></blockquote><p>That would be a problem, as trying to use the same tag for
different physical objects always is in OSM. If I<br></p><p><br></p><div>gis=> select count(*) from [some database table] where amenity

that data consumers can easily do that. At the place where I
detect charging stations I don't have that capability: <a target="_blank" rel="noopener noreferrer" class="" href="https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/master/style.lua#L1492">https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/master/style.lua#L1492</a> .<br></p><p>If the same tag must be used for both, the only way to tell
"single charge point" from "group of chargers" is to have a tag
that is set to indicate which is which. If "newtag=single" it
means it's a single charge point, if "newtag=group" it's a group,
and if "newtag" is not set, we don't yet know, and need to
encourage local mappers to add the tag.<br></p></blockquote><div dir="auto">I guess that can be useful.<br></div><div dir="auto"><br></div><div dir="auto">How you distinguish "marks group of chargers" and "marks single charger within<br></div><div dir="auto">group of chargers" now?<br></div><div dir="auto"><br></div><div dir="auto">Is it "ideally proposal would introduce this ability" or "proposal breaks existing ability"?<br></div> </body>
