A simper way to describe this would be to say that: `power=line` is for “transmission” https://en.wikipedia.org/wiki/Electric_power_transmission <https://en.wikipedia.org/wiki/Electric_power_transmission>
`power=minor_line` is for “distribution” https://en.wikipedia.org/wiki/Electric_power_distribution <https://en.wikipedia.org/wiki/Electric_power_distribution> Trying to define this based on line voltage or tower heights or danger to aircraft is silly. Transmission and distribution lines can be located underground. > On Oct 13, 2015, at 4:22 AM, David Marchal <pene...@live.fr> wrote: > > Hello, there. > > I saw conflicting points of view regarding the difference between these two > ways for modelling aerial power lines: some say that it is the voltage which > matters, others say that it's the visibility difference that matters, others > say that it's the danger for planes that matters, and some use other reasons > or some of these together.
