Cannot view WMSLayer nwhen basemap set

DanielNwankwo · ‎05-22-2014

I have found that if my map object has a basemap property set then the WMSLayer does not display when retrieving by resourceInfo method. When I do not set the basemap property then the WMSLayer is displayed.

This is not very useful as I need to see the basemap. I dont know if this is a bug or me, I have no solution at the moment so any help greatly appreciated.

Here is the url 'http://npdwms.npd.no/NPD_FactMap.asp' and layer is 'Quadrants'

I tried setting the visibility to no avail.

I do not have this problem when retrieving by proxy method but I would rather use the resourceInfo method

Here is my code

My colleague miraculously has found a workaround for displaying this WMS with the basemaps. Just before the WMSLayer object is added as a layer to the map, you overwrite the spatialReferences array in the WMSLayer object setting the CRS to 3857

wmsLayer.spatialReferences[0] = 3857

after this is done now add the layer to the map and hey presto the WMS layer appears.
In the background this forces a change to one of the attributes that is set on the WMS url from

&CRS=EPSG:102100

TO

&CRS=EPSG:3857

Here is the bit of code in full

function addBGS(WMSLayer,WMSLayerInfo,Extent,lang){
            var layerInfo = new WMSLayerInfo({name:"GBR_BGS_625k_BLS",title:"GBR BGS 1:625k Bedrock Lithology"});

            var resourceInfo = {
                extent: new Extent(-8.64846,49.8638,1.76767,60.8612,{wkid: 4326}),
                layerInfos: [layerInfo]
            };
            var wmsLayer = new WMSLayer("http://ogc.bgs.ac.uk/cgi-bin/BGS_Bedrock_and_Superficial_Geology/wms",
                    {
                        resourceInfo: resourceInfo,
                        visibleLayers: ["GBR_BGS_625k_BLS"]
                    }
            );

           wmsLayer.spatialReferences[0] = 3857;
            map.addLayer(wmsLayer);
        }

If we do not set the spatialReferences array as above, we get the response error message below

Anyway that's where I am at the moment, hope this helps someone and thanks Jeff.

I know it's late, but can you mark this as the correct answer? This helped several people already (one of them linked me here) and can help even more if available without scrolling through whole discussion.

Thanks!

3857 and 102100 should the same.

If this makes your WMS work, then the WMS is set up with 3857 but not 102100. This is just a config issue with the data provider.
