I have removed plenty of its nodes at it has still more then enough.
The rendering issue is gone after the correction of the data?
Looks a bit better but still not quite a round circle: http://img543.imageshack.us/img543/1677/rotonde.jpg
I think that there are no round elements in OSM nor in Garmin. In order to display a roundabout there are several strait segments. You seem to use a quite thin line to display your roads. I am using bigger lines, so it is less evident to see the segments and optically it displays smoother. On the top (north) side of your roundabout appears a dent. I do not know why, but I think that there are still much to many nodes to describe this small roundabout. -- Sincerely Hendrik Oesterlin - email hendrikmail2002@yahoo.de
