    placemark.attributes = placemarkAttributes;

    // Create the highlight attributes for this placemark. Note that the normal attributes are specified as
    // the default highlight attributes so that all properties are identical except the image scale. You could
    // instead vary the color, image, or other property to control the highlight representation.
    highlightAttributes = new WorldWind.PlacemarkAttributes(placemarkAttributes);
    highlightAttributes.imageScale = 1.2;
    placemark.highlightAttributes = highlightAttributes;

    // Add the placemark to the layer.
    placemarkLayer.addRenderable(placemark);

    // Add the placemarks layer to the WorldWindow's layer list.
    wwd.canvas.appendChild(newA);
    wwd.addLayer(placemarkLayer);
};
