[OpenLayers-Users] GetFeature and reprojection GET Method

[afrozk]

See if this helps,

I have a wms layer(in epsg 4326)  over the google base layer
I use GetFeatureInfo to get the data nd it works fine for me

var extent     = new
OpenLayers.Bounds(-4037508.34,-20037508.34,20037508.34,20037508.34);
var map_options   = {'maxExtent': extent,numZoomLevels:6,restrictedExtent:
extent,projection: new
OpenLayers.Projection("EPSG:900913"),displayProjection: new
OpenLayers.Projection("EPSG:4326")}
var coverage_options  = {isBaseLayer: false, opacity:
0.4,displayInLayerSwitcher: true};
var google_Poptions   = {isBaseLayer: true, displayInLayerSwitcher:
true,sphericalMercator: true ,reproject: true,type: G_PHYSICAL_MAP};

// Inside init
map = new OpenLayers.Map( 'map', map_options);
google = new OpenLayers.Layer.Google("Google Physical",google_Poptions);
   region1_layer  = new OpenLayers.Layer.WMS( "Region1 ",
                    "http://" + server + "/cgi-bin/mapserv.exe?",
                    {map:'../htdocs/mgt/c1.map',layers:
"region1",transparent: "TRUE", format: "image/png" ,counter1:0},
     coverage_options);
map.addLayers([google,region1_layer]);

Thanks
