Hi all, One of the things I noticed at SOTM was that the Aston campus has two little wind turbines, perched on top of some of the buildings. They're quite small, yet the standard OSM style shows them even at zoom level 15, as if they're significant landmarks:
<http://www.openstreetmap.org/?mlat=52.4849&mlon=-1.8899#map=15/52.4849/-1.8899> The relevant tags on these items are generator:source = wind power = generator power_source = wind I've no problem with them being rendered, but I'd suggest it'd be better to show them only at finer zoom levels. However, as far as I can tell our renderers don't have much choice, because there's no tagging that distinguishes a tiny building-mounted turbine from a massive free-standing turbine. http://wiki.openstreetmap.org/wiki/Tag:generator:source%3Dwind In open areas with wind-farms, the turbines are significant landmarks, so I can see it makes sense to render them then. I'm suggesting this is not a problem we can leave for the renderer, since the renderer doesn't know the turbine's significance - it doesn't know if the turbine is 5 feet high or 50 feet high. (This implies that tagging the height could be a solution... might be a bit tricky to get correct height data though...)
