We are not talking about stop to differentiate power lines but to use different tags to do so.
By landscape : importance=* may support the difference between "big" and "small" power lines. http://wiki.openstreetmap.org/wiki/Proposed_Features/Importance power=line + importance=local power=line + importance=regional power=line + importance=minor power=line + importance=major and so on On supports : color=*, structure=*, height=* By power grid function : power=line + usage=distribution power=line + usage=transmission power=line + usage=traction and so on I completely second what Ralph said. The problem is also no one has really the same point of view regarding power lines classification. And we are forcing people who can't/don't want to handle such a choice between minor/major, huge/small, useful/not useful. Finally, how would you tag such feature ? https://www.google.fr/maps/@46.0051218,6.6292445,3a,75y,140.55h,108.7t/data=!3m6!1e1!3m4!1snMHy5MWRsC1Q39kjLUSkag!2e0!7i13312!8i6656 cheers François 2015-10-14 17:17 GMT+02:00 David Marchal <pene...@live.fr>: > Indeed, mappers aren't supposed to know everything, neither the recommended > modelling nor the technical details of power lines, but the landscape > criteria seems simple enough to allow them to understand it if they are > informed about it; besides, even if they are not aware of it, experienced > mappers can correct and detail it later, so the distinction won't be useless > at all, even if it isn"t used at the first mapping.
