Great. So OSM have those data.
I remember i made some sugerences time ago talking about array, for lines of objetcs like those powerlines, or chairlifts at ski stations.
But i was not sure if the data was covering those things. It seems yes. And not only powerlines, i was checking righ now, and i think ski stations chairlifts data are also there.
So Outerra can be filled with powerlines and ski station. Now its a matter to get a system for make automatically the cords between lines, and also chairlifts, and even chairs moving along the cords at sky stations, as i explained in those sugerences time ago.
