[OpenLayers-Users] Query with projection other than 4326

[Alexandre Dube]

Hi everybody,

  I'm trying to find a way to get a GetFeatureInfo request working with 
a projection other than 4326.  I use a mapfile which has the epsg:32198 
projection.

  My query returns no result if I use the proj. 32198.  I have to use 
4326 and the result is not always correct, i-e if I click the "a" 
region, I get the "b" region besides the "a" as a result...

  I also tried an other query.  I added a vector layer to my map with 
the 32198 projection.  Using a bounding box, I query a WMS GetFeature 
and add the features to the vector layer ( which are polygons of 
regions).  The vector drawn looks like it's not in 32198 proj. but in 
4326.  See code below.

  To be short, my question is how can I use any type of query using an 
other projection than 4326 ?

-------  a part of my GetFeature code sample ----------

        var oControl = new OpenLayers.Control();
        OpenLayers.Util.extend(oControl, {
            draw: function () {
                this.box  = new OpenLayers.Handler.Box( oControl,
                    {"done": this.notice},
                    {keyMask: OpenLayers.Handler.MOD_SHIFT});
                this.box.activate();
            },

            notice: function (bounds) {
                OpenLayers.Util.getElement('nodeList').innerHTML =
                "Loading... please wait...";

                //Get LonLat from the 2 pixels of the Bounding Box
                var ll = oMap.getLonLatFromPixel(new OpenLayers.Pixel(
                    bounds.left, bounds.bottom));
                var ur = oMap.getLonLatFromPixel(new OpenLayers.Pixel(
                    bounds.right, bounds.top));

                var sUrl =  olMRC.getFullRequestString({
                           REQUEST: "GetFeature",
                           SERVICE: "WFS",
                           TYPENAME: "NAME_OF_LAYER",
                           VERSION: "1.0.0",
                           MAXFEATURES: "50",
                           BBOX: ll.lon + "," + ll.lat + "," +
                                 ur.lon + "," + ur.lat
                });
                document.getElementById('urlTextInput').value = sUrl;

                OpenLayers.loadURL(sUrl, '', this, drawVectorMRC);
            }
        });

function drawVectorMRC(response) {
    var oFormatGML =  new OpenLayers.Format.GML();
    var oFeatures = oFormatGML.read(response.responseText);
   
    olVectorMRC.destroyFeatures();
    olVectorMRC.addFeatures(oFeatures);
}
