[OpenLayers-Users] HELP!!! How implement Filter in WMS Layer

Fri Sep 18 16:40:33 EDT 2009

hi salas,

you request the layer Cuba, but in the SLD_BODY you describe rules for the
layer topp:cuba. Change it to Cuba. And if your SLD_BODY has escaped chars,
change them too (%3D =, %23 #).

you can try this

<http://urano/cgi-bin/mapserv.exe?map=d:/ms4w/apps/OpenLayers/data/educacion
.map>
http://urano/cgi-bin/mapserv.exe?map=d:/ms4w/apps/OpenLayers/data/educacion.
map&Service=WMS&Version=1.1.1&Request=GetStyles&Layers=Cuba

to get a sld file for the layer defined by the mapfile .

Arnd

Arnd, 

Thanks very very much for your help, the map is show, as you said I forgot
to insert a projection block.

My finaly objetive is obtain one maps change the sld_body params, but its
don't affect the maps.

This is part of my code 
***********************
 function init(){
   var options = {
   projection: new OpenLayers.Projection("EPSG:4267"),
   displayProjection: new OpenLayers.Projection("EPSG:4267"),
   units: 'degrees',
   maxResolution: 0.05115824837085553,
   maxExtent: new
OpenLayers.Bounds(-86.09240990784447,19.463031059956343,-72.99589832490545,2
3.634939943479928),
   controls : []
   };

   map = new OpenLayers.Map('map',options); 

             // setup single tiled layer

     layer0 = new OpenLayers.Layer.WMS( 

"Cuba","http://urano/cgi-bin/mapserv.exe?map=d:/ms4w/apps/OpenLayers/data/ed
ucacion.map",
           {    layers: "Cuba",
                format: "image/png",
                 transparent: 'true'    
           });

             layer0.isBaseLayer=true;

            map.addLayers([layer0]);

            // setup controls and initial zooms
            map.addControl(new OpenLayers.Control.PanZoomBar());
            map.addControl(new OpenLayers.Control.Navigation());
            map.addControl(new OpenLayers.Control.Scale($('scale')));
            map.addControl(new
OpenLayers.Control.MousePosition({element:$('location')}));
            map.addControl(new OpenLayers.Control.LayerSwitcher());
       }  

function Mostrar()
{
 map.layers[0].mergeNewParams({SLD_BODY:'<StyledLayerDescriptor
version%3D"1.0.0"><UserLayer><Name>topp:cuba</Name><UserStyle><Name>UserSele
ction</Name><FeatureTypeStyle><Rule><Filter

Hi salas,

as the message says, you have forgotten to insert a projection block in the
mapfile on map level.

  PROJECTION
    'init=EPSG:4267'
  END

Hi salas,

Now have a look at your OpenLayers code. I suggest, that you have no options
set for your map.

            var options = {
                projection: new OpenLayers.Projection("EPSG:900913"),
                displayProjection: new OpenLayers.Projection("EPSG:4326"),
                units: "m",
                numZoomLevels: 18,
                maxResolution: 156543.0339,
                maxExtent: new OpenLayers.Bounds(-20037508, -20037508,
20037508, 20037508.34),
                controls      : []
            };

            map = new OpenLayers.Map('map', options); 

It is an example for the google projection.

Hi,

You have not added the projection block to the layer. Perhaps it is needed,
i'm not sure. I declare always a projection for the map (as default output),
and for the layers (the data have to be in a specific projection).

If the problem remain, do the next:

The message comes, when the WMS requests for an EPSG, that is not declared
in the wms_srs tag. Have you in OpenLayers the projection for the map set to
EPSG:2085. For the layer you need not declare the SRS, because OpenLayers
add the EPSG from the map to the SRS parameter for the WMS layer.

Use right click on your map to get the url for one tile of your WMS. Paste
the url into the addressbar of your browser. The errormessage should be the
same. But now you can inspect the WMS request. Look at the SRS. Is it
&SRS=EPSG:2085?

Arnd
