<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,
|
|
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>
