[OpenLayers-Users] Mapserver labels, Google and WMS in one map

Tue Aug 29 12:35:37 CDT 2006

Hello Arnd,

Having two different WMS layers toguether (at the same view) is useful
as it allows, for example, to take part of cities names (using
Google's one) and very high detail definition (now with NASA's one).

Yes, it's currently possible to do as Erik has previously told you:

"
ex:

   var wms = new OpenLayers.Layer.WMS("OpenLayers WMS",
"http://dgtad.dti.digitro.com.br:8080/mapserver_wms/wms", {layers:
'rio_grande_do_sul,limite_municipal, transparent: true'} );

 -- OR --

   var wms = new OpenLayers.Layer.WMS("OpenLayers WMS",
"http://dgtad.dti.digitro.com.br:8080/mapserver_wms/wms", {layers:
'rio_grande_do_sul,limite_municipal'} ); wms.isBaseLayer = false;
"

Hope this helps.

Regards,
