<h1>ol-ext: WMS Capabilities control</h1>
</a>
<div class="info">
<b>ol/control/WMSCapabilities</b> is a control to load WMS layers on ol maps.
<br/>
It displays a dialog to select the service you want to add using getCapabilities of the service.
<br/>
Some services may not respond correctly because of
<a href="https://en.wikipedia.org/wiki/Cross-origin_resource_sharing">CORS policies</a>
and you may have to use a proxy to access the getCapabilities...
<br/>
Listen to the <i>load</i> event to get the selected layer or options to create it.
<br/>
Look at the console for the layer definition to insert into your code.
