But if there is only 1 PV panel osm object in the plant, it's not possible to use power=plant + power=generator on a same object. Is it <span>appropriate to create a relation with only one element?</span><br></div><div><br></div><div dir="ltr" data-setdir="false">parent: type=site + power=plant (relation)<br></div><div dir="ltr" data-setdir="false">_member: power=generator (node or area)</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Thanks,</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Tan<br></div></div></body></html>
