[mapserver-users] mapserver not generating proper map

Mon Mar 22 02:26:39 PDT 2010

Hi,

I am generating a simple map but mapserver is not generating a proper map.
In fact initially it produced a proper one but after that due to code
changes or some other reason started producing this one.
My code to call mapserver is:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

<html xmlns="http://www.w3.org/1999/xhtml">

     <script  
type="text/javascript"src="OL28/OL28/lib/OpenLayers.js"></script> 
      <script type="text/javascript" language="javascript">
          var mapview, layer, layer1, map;

         function init() {

             //alert("in init");
             map = new OpenLayers.Map('<%=map.ClientID%>');

             //
             layer = new OpenLayers.Layer.WMS("OpenLayers WMS",
                "http://172.16.0.144:9000/cgi-bin/mapserv.exe?", { map:
'Shape/newwr1.map', layers: 'STATE', 'format': 'png' });

             //layer1 = new OpenLayers.Layer.WMS("RLine",
"http://172.16.0.144:9000/cgi-bin/mapserv.exe?", { map: 'Shape/newwr1.map',
transparent: 'true', layers: 'RailwayStations', 'format': 'png' });

             highlightLayer = new OpenLayers.Layer.Vector("Highlighted
Features", {
                 displayInLayerSwitcher: false,
                 isBaseLayer: false
             }
        );
             map.addLayers([layer]);
             map.setCenter(new OpenLayers.LonLat(73.25, 20.35), 6);
             //            for (var i in infoControls) { 
             //            infoControls[i].events.register("getfeatureinfo",
this, showInfo);
             //            map.addControl(infoControls[i]); 
             //        }

             map.addControl(new OpenLayers.Control.LayerSwitcher());
             map.zoomToMaxExtent();
             //        infoControls.click.activate();

         }  

      </script>
</head>
<body onload="init()">
    <form id="form1" runat="server">
    <div id="map" runat="server" style="width:600px;height:600px">

    </div>
    </form>
</body>

and my map file is:

But when my map comes up it is having a BBOX size of 256 * 256.
the url of the generated map is as follows:

http://172.16.0.144:9000/cgi-bin/mapserv.exe?MAP=Shape%2Fnewwr1.map&LAYERS=STATE&FORMAT=png&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A4326&BBOX=0,-90,180,90&WIDTH=256&HEIGHT=256

Why does it happen?
Is it because of some wrong openlayers code I have written or some bug?
What should I do to get back to the desired size i.e 600 * 600

Thanks for your attention & efforts.
