- <p>The above map has an overview map control that is created with

- the overview map control defaults to a geographic projection.</p>
- <div id="map2"></div>
- <p>The second map has an overview map control that is created with
- non-default options. In this case, the mapOptions property of the
- control has been set to use non-default projection related properties,
- and the layers property has been set to use a layer different from the main
- map. In addition, any other properties of the overview map control can be
- set in this way.</p>
