I was wondering if you could answer one more question for me.

I looked at the .prj file for the shapefile and I think I set it up correctly. The thing that confuses me is that the coordinates that I have for a point in Hawaii still does not show up. The coordinates I have are Lat = 19.7229 and Long = -156.004. When I put these into Google Maps it gives me a point that is on the West coast of Hawai'i island. Looking at the Wikipedia page it looks like Google Maps uses a variation on the Mercator projection type where I am using Transverse Mercator now.

My code so far is...

<igMaps:XamMap x:Name="hawaiiMap" IsClickable="False" WindowAnimationMode="None"
           IsHitTestVisible="False" ViewportBackground="Black" Height="500" Width="500" >

    </igMaps:XamMap.Layers>

private void symbols_Loaded(object sender, RoutedEventArgs e)
{
    Point p = hawaiiMap.MapProjection.ProjectToMap(new Point(19.7229, -156.004));

    this.hawaiiMap.Layers[2].Elements.Add(new SymbolElement()
    {
        SymbolOrigin = p,
        SymbolType = MapSymbolType.None
    });

    this.hawaiiMap.Layers[2].DataBind();
}

private void hawaiiLayer_Imported(object sender, MapLayerImportEventArgs e)
{
    if (e.Action == MapLayerImportAction.End)
    {
        hawaiiMap.Layers[2].WorldRect = hawaiiMap.Layers[0].WorldRect;
        this.hawaiiMap.Layers[2].DataBind();
    }
}

Awesome thanks!
