Does georsslayer support georss:box... (or only point), No renderer works..

Question

POSSIBLE BUG WITH GEORSSLAYER OBJECT... DOESN'T SUPPORT GEORSS BOX.. (Mostly Supports.. it just doesn't show up on the map) See Post 3 for more details I have a sample georss working using the earthquakes... I'm trying to consume a georss feed that has an a polygon... actual xml looks like this.. -156.00000 -51.38000 176.20600 78.57000 The good news is that the GeoRssLayer loads. And I can see the graphics loaded in my map object. (They are an envelope) however I can't get a renderer to actually display them. I've primarily tried the SimpleFillSymbol with no luck. goorssdoesNOTshow.png georssdoeswork.png ScreenGrab_ArcGISProExportedPDF_inAdobeIllustrator2.jpg ScreenGrab_ArcGISProExportedPDF_inAdobeIllustrator1.jpg

I think this is due to the fact that the feed I was trying to consume had it's lat/long reversed.

I feel more confident of my assessment after further test. This xaml snippet (using a georss feed that utilizes polygon) draws fine.. 40.859449062067746 -73.773361265529715 40.854830471980755 ... 40.859449062067746 -73.773361265529715 This code (using a georss feed that utilizes box) does not draw.. same renderer as above -156.00000 -51.38000 176.20600 78.57000

I think this is a bug with the GeoRssLayer object

So GeoRss:box Esri georsslayer converts this to a Envelope. (See first post thumbnail) (box is part of the georss spec .. see http://georss.org/simple)

That is cool, however, envelopes don't seem to draw on the map.. (like points/lines/polygons do)

Looks like others have found that envelopes don't draw also..

here is some sample code I wrote.. //POLY WORKS
            System.Windows.Media.SolidColorBrush orangecolor = new SolidColorBrush(Colors.Orange);
            SimpleFillSymbol sampleFillSymbolorange = new SimpleFillSymbol() { Fill = orangecolor, BorderBrush = orangecolor, BorderThickness = 3, };

GraphicsLayer graphicslayerPoly = new GraphicsLayer() { ID = "PolygonWorks", Opacity = .5 };

ESRI.ArcGIS.Client.Geometry.PointCollection circlePts = new ESRI.ArcGIS.Client.Geometry.PointCollection();
            circlePts.Add(new MapPoint() { X = -60, Y = -30 });
            circlePts.Add(new MapPoint() { X = -30, Y = 00 });
            circlePts.Add(new MapPoint() { X = 00, Y = 00 });
            circlePts.Add(new MapPoint() { X = 00, Y = -30 });
            circlePts.Add(new MapPoint() { X = -30, Y = -60 });

ESRI.ArcGIS.Client.Geometry.Polygon isolationZonePts = new ESRI.ArcGIS.Client.Geometry.Polygon();
            isolationZonePts.Rings.Add(circlePts);
            isolationZonePts.SpatialReference = new SpatialReference() { WKID = 4326 };
            
           //ENVELOPE DOESN'T 
            graphicslayerPoly.Graphics.Add(new Graphic() { Geometry = isolationZonePts, Symbol = sampleFillSymbolorange });
            System.Windows.Media.SolidColorBrush purplecolor = new SolidColorBrush(Colors.Purple);
            SimpleFillSymbol sampleFillSymbol = new SimpleFillSymbol() { Fill = purplecolor, BorderBrush = purplecolor, BorderThickness = 20 };
            GraphicsLayer graphicslayerEnvelope = new GraphicsLayer() { ID = "EnvelopeFails", Opacity = .5 };
            Envelope envelope = new Envelope(30, 30, 0, 0);
      MyMap.Layers.Add(graphicslayerPoly);
            MyMap.Layers.Add(graphicslayerEnvelope);
