I would like to add a UIElement at a certain GPS area. For example add an the coat of arms image of Moscow over the city itself. Thus when i zoom in the map the image will become bigger and when i zoom out it will downsize. As far as i know it's possible to add a UIElement at a sertain aria. Here is the example code:

InformationLayer layer = new InformationLayer();
Rectangle rect = new Rectangle() { Width = 100, Height = 80, Fill = new SolidColorBrush(Colors.Black) };
InformationLayer.SetGeographicalSize(rect, new Location(55, 37));

Thus the rectangle is positioned with it's top left corner being exactly at (55,37). When i drag the map the rectangle remains where it should be. But when i zoom in it's size doesn't grow and when i zoom out it doesn't shrink. Is there a way to set that rectangle over a whole area? For example Microsoft's MapControl  a MapLayer.SetPositionRectangle(rect, boundingRectangle);

Thanks alot.

Hello JR,

You can add map shapes to the InformationLayer in RadMap, here is an example:

<telerik:RadMap x:Name="radMap1"  ZoomLevel="12" Center="37.684297,-122.06924">
            <telerik:InformationLayer Name="informationLayer1">
                <telerik:MapRectangle Location="37.684297,-122.06924"
                                       StrokeThickness="2" />

private string VEKey = "<your_key_goes_here>";
        public Example()
            this.Loaded += new RoutedEventHandler(MainPage_Loaded);
        private void MainPage_Loaded(object sender, RoutedEventArgs e)
            BingMapProvider provider = new BingMapProvider(MapMode.Aerial, true, this.VEKey);
            this.radMap1.Provider = provider;
            MapRectangle rectangle = new MapRectangle()
                Location = new Location(37.684297, -122.06924),
                Width = 1,
                Height = 1,
                RadiusX = 0.1,
                RadiusY = 0.1,
                Fill = new SolidColorBrush(Color.FromArgb(127, 255, 255, 0)),
                Stroke = new SolidColorBrush(Colors.Red),
                StrokeThickness = 2

You can find more details about map shapes in this help topic.
