The 3 is Gascoyne Avenue, Hillcrest, South Australia seem to match that idea closely. I hope to grab some pictures of them when I'm over that way on Tuesday. > Not wanting to put words in Darrin's mouth, but I think we are on the > same page.

I'm totally on your wavelength with respect to the making our usage match the worlds usage, and making a new tag when we have something different, and I get the impression a couple of others on here have similar opinions in a general sense. However (isn't there always a However, or a But or some such thing ;)... I've been thinking about my stance with this and I think I've distilled why it's been bugging me. I tend to make sure that any reasonably size island of any sort is represented by separating the ways since said island is blocking normal traffic movement between the 2 carriageways (about the only ones I skip are the small lane separator islands you get on the side roads in some small T-junctions, but I'll clock that up to my laziness ;). So given even the smallest roundabouts are islands of quite a large size I like to see them represented on the map as a separating of the ways. So after realising this I can't actually stand in support of junction=roundabout on a point (or some other similar proposal) as a permanent fixture, but would fully support it as a 'temporary' tag to indicate at some point someone with my kind of island obsession comes along and puts in the details. -- =b _______________________________________________ Talk-au mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-au
