[gdal-dev] Simple circle in OGR

[Renison]

Figured it out like this:
            SpatialReference defaultGeoSys = new SpatialReference("");
            defaultGeoSys.SetWellKnownGeogCS("EPSG:4326");

            //define a circle using point and buffer        
            string pointlineString = "POINT (" + longitude + " " + latitude
+ ")";
            Geometry center = OGR.Ogr.CreateGeometryFromWkt(ref
pointlineString, defaultGeoSys);
            Geometry bufferDefn = center.Buffer(radiusInMiles, 10000);
            Geometry bufferDefnPolygon = bufferDefn.GetGeometryRef(0);

            Geometry actualCircle = Ogr.ForceToPolygon(bufferDefnPolygon);

The actualCircle serves my purpose of within and intersects. This is just a
fyi if someone else has an issue like this.
