<p>The above map has an overview map control that is created with
the default options. Much like a regular map, the map contained by
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.
In addition, any other properties of the overview map control can be
set in this way.</p>
