the problem with this is that 'bus stop' (and canal mooring, etc,) implies a place where the bus stops, which is on the road. the fact the bus shelter, or sign, or bench, is some distance off to the side of the road shouldn't matter - the bus itself stops on the road, so the node imo should be part of the way if the bus stop is off to the side of the road, i.e. not connected to it, then the bus can't physically get to it, which seems very wrong or, consider from the pedestrian's point-of-view: it is assumed for all roads except motorways and where explicitly stated, that there is foot=yes access. in which case, the footpath/sidewalk/pavement is therefore part of the way which represents the road; we don't draw a separate way off to one side, running parallel. the bus stop must be on the footpath for the pedestrian to be able to walk up to it, so again it must be part of the way this problem is i think muddled by the fact we represent an area (a road) with a linear object (a way), which theoretically has zero width, so the natural step from this is to say: 'the way represents the centre of the road, and the bus stop/canal mooring is not in the centre of the road, it's at the side of the road, so I'll put it to one side of the way' as for placing the node to one side of the way in order to get the icon to be placed correctly, this sounds a lot like 'tagging for the renderer' _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
