[OpenLayers-Dev] Integrating Google Maps and Mapserver

Tue Jul 3 04:28:11 EDT 2007

Bradley,

var mapservwms = new OpenLayers.Layer.WMS("De Bortoli Mapserver",
['http://192.168.1.130/cgi-bin/mapserv?map=/usr/local/mapfiles/dbwwms.map&service=wms&version=1.1&request=getmap&layers=dbwap,bcadbd,hcadbd'])<http://192.168.1.130/cgi-bin/mapserv?map=/usr/local/mapfiles/dbw.map&service=wms&version=1.1.1&request=getmap&layers=dbap>

I suggest you have a look into the examples directory in OpenLayers.
Essentially OpenLayers takes care of a lot of the underlying WMS protocol
stuff, like the protocol and service parameters. For your server the URL to
put into the OpenLayers.Layer.WMS would be
' http://192.168.1.130/cgi-bin/mapserv?map=/usr/local/mapfiles/dbwwms.map',
<http://192.168.1.130/cgi-bin/mapserv?map=/usr/local/mapfiles/dbw.map&service=wms&version=1.1.1&request=getmap&layers=dbap>
the layers go into a separate argument as a list.

Try to get the examples/wms.html to work -- once this is working, substitute
your URL and layer names.
Otherwise you will keep banging your head against the wall.
