Hi Philipp,
the function OpenLayers.Layer.WMS.prototype.getFullRequestString have to be load after the OpenLayers script(s) are loaded (the function overwrites the original function from OpenLayers) and before the declaration of the Layer.WMS.
It should be something in this way:
...
<script src="../lib/OpenLayers.js"></script>
<script type="text/javascript">
OpenLayers.Layer.WMS.prototype.getFullRequestString = function(newParams,altUrl)
{
try{
var projectionCode=typeof this.options.projection == 'undefined' ? this.map.getProjection() : this.options.projection;
}catch(err){
var projectionCode=this.map.getProjection();
}
this.params.SRS = projectionCode=="none" ? null : projectionCode;
return OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(this,arguments);
}
function init()
{
var boundaries = new OpenLayers.Layer.WMS( "Boundaries",
"http://ag-0988a/ArcGIS/services/StateBoundaries_WGS84_WM_102113/MapServer/WMSServer?",
//parameter
{ layers: '0',
format: 'image/png',
transparent: true
},
//options
{ visibility: true,
isBaseLayer: false,
singleTile: false,
projection : 'EPSG:102113'
}
);
...
}
</script>
</head>
<body onload="init()">
...
Good Luck
Arnd

Hi Arnd,
thank you for the response, unfortunately I don't know where to use or replace your code snippet in my .js file.
The WMS I work on has the following parameters.
var boundaries = new OpenLayers.Layer.WMS( "Boundaries",
"http://ag-0988a/ArcGIS/services/StateBoundaries_WGS84_WM_102113/MapServer/WMSServer?",
{layers: '0',
//projection: 'EPSG:102113',
format: 'image/png',
transparent: true
},{
visibility: true,
isBaseLayer: false,
singleTile: false }
);
I added the projection: 'EPSG:102113' but it didn't seem to change anything. Where would go your code? Would it replace the the whole section of var boundaries or would it be an additional part?
I'm a little lost.
Regards, Philipp

Hi,
i use this code to be able to pass a different projection code to the getFullRequestString of the Layer.WMS.
If in the options for the Layer.WMS projection is set, then it will be used instead of the map.projection.
OpenLayers.Layer.WMS.prototype.getFullRequestString = function(newParams,altUrl)
{
try{
var projectionCode=typeof this.options.projection == 'undefined' ? this.map.getProjection() : this.options.projection;
}catch(err){
var projectionCode=this.map.getProjection();
}
this.params.SRS = projectionCode=="none" ? null : projectionCode;
return OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(this,arguments);
}

Betreff: [OpenLayers-Users] WMS from ArcGIS Server on top of google maps -Parameter 'srs' contains unacceptable value.
Hi list,
I have a layer of the states and territories of Australia and would like to overlay it on google maps using openlayers.
The Australia layer is a WMS which is on my ArcGIS Server. I use EPSG:102113 which represents in the ESRI world the WGS_1984_Web_Mercator.
The WMS has following capabilities:
<Layer queryable="1">
<Name>0</Name>
<Title>StateBoundaries_1</Title>
<Abstract>StateBoundaries_1</Abstract>
<CRS>CRS:84</CRS>
<CRS>EPSG:4326</CRS>
<CRS>EPSG:102113</CRS>
−
<EX_GeographicBoundingBox>
<westBoundLongitude>0.000870</westBoundLongitude>
<eastBoundLongitude>0.001429</eastBoundLongitude>
<southBoundLatitude>-0.000393</southBoundLatitude>
<northBoundLatitude>-0.000082</northBoundLatitude>
</EX_GeographicBoundingBox>
<BoundingBox CRS="CRS:84" minx="0.000870" miny="-0.000393" maxx="0.001429" maxy="-0.000082"/>
<BoundingBox CRS="EPSG:4326" minx="-0.000393" miny="0.000870" maxx="-0.000082" maxy="0.001429"/>
<BoundingBox CRS="EPSG:102113" minx="96.816766" miny="-43.740510" maxx="159.109219" maxy="-9.142176"/>
the openlayer setup looks like this
var geographic = new OpenLayers.Projection("EPSG:4326");
var mercator = new OpenLayers.Projection("EPSG:900913"); //aka EPSG:3785
var gda94 = new OpenLayers.Projection("EPSG:4283");
var world = new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34)
var mapOptions = {
projection: mercator,
displayProjection: geographic, //for Mouse Position
maxExtent: world,
restrictedExtent: world,
units: 'm',
numZoomLevels: 22,
maxResolution: 156543.0339,
controls: [new OpenLayers.Control.PanZoomBar(),
new OpenLayers.Control.KeyboardDefaults()]
};
var map = new OpenLayers.Map( 'map', mapOptions );
//Google Physical
var gphy = new OpenLayers.Layer.Google("Google Physical",
{type: G_PHYSICAL_MAP,
sphericalMercator: true,
isBaseLayer: true,
numZoomLevels: 22,
maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34)
});
map.addLayer(gphy);
var boundaries = new OpenLayers.Layer.WMS( "Boundaries",
"http://ag-0988a/ArcGIS/services/StateBoundaries_WGS84_WM_102113/MapServer/WMSServer?",
{layers: '0',//srs: 'EPSG:102113',
format: 'image/png',
transparent: true
},{
visibility: true,
isBaseLayer: false,
singleTile: false
}
);
map.addLayer(boundaries);
The error message is Parameter 'srs' contains unacceptable value.
I know that the google layer is defined with EPSG:900913 and my WMS has EPSG:102113, but I can't set the EPSG to 900913 because ESRI doesn't support it.
How do I go from here, what are my options? I need to use Google as baselayer but can reproject all WMS as I like.
Any suggestions are more than welcome.
Regards, Philipp
