RE: [georss] Scaling/size of geographical entities

Hi,

There is a CircleByCenterPoint in GML which has a center point and
radius.

	<gml:CircleByCenterPoint>
		<gml:pos>45.256 -110.45</gml:pos>
		<gml:radius uom="#meters">500</radius>
	</gml:CircleByCenterPoint>

Of course there will be issues of the meaning of this when placed into a
non-flat manifold - but for flat earth's this is ok.

I think radius is in dispute... I forget who likes it and who does  
not. The issue, as far as I recall, is that GML does not have a  
circle that's defined by a point and a radius so GeoRSS Simple can't  
have one.
