Layer Constructor

The next step to creating a viewer is to add a layer to the Map. OpenLayers supports many different data sources, from WMS to Yahoo! Maps to WorldWind. In this example, the WMS layer is used. The WMS layer is an example provided by MetaCarta.

var wms = new OpenLayers.Layer.WMS(
  "OpenLayers WMS",
  "http://labs.metacarta.com/wms/vmap0",
  {'layers':'basic'} );
map.addLayer(wms);
