Cannot view WMSLayer nwhen basemap set

DanielNwankwo — Thu, 22 May 2014 13:42:02 GMT

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

most likely adding the basemap is slowing down map creation, so you are trying to add the wms layers prior to the map being ready

try

map.on('load', lang.hitch(function(){
addNorway(WMSLayer,WMSLayerInfo,Extent);
addBGS(WMSLayer,WMSLayerInfo,Extent);
}))

Hello Jeff,
I tried your suggestion but it did not work.

The load event seems to be triggered before the basemap is displayed so im thinking maybe there is another event that could be set instead, assuming that this is the right track.

Thanks, more ideas pls.

try

1.create the map without the basemap
2. manually add the basemap
3. basemap.on('load', <add wms>)

Hey Jeff,
Tried but to no avail, also set a timeout (5secs) before creating the WMSLayer just to be sure but no joy also, strange problem
Theres a chocolate bar waiting if this one is solved!!!

Thanks

ok,
i would alert(map.layerIds) after the wms load. That way you can see if they are there and not drawing, or if they are not being added

Side note .. oh wait

Your wms services are 102100 (3857) right? They HAVE to be if you want to add them to a tiled basemap

Hi Jeff
Not too certain how the coordinate system is used so may have to do some reading before I can answer.

i can tell by your extent that they are not (wkid 4326). that is wgs 84 (lat long). You need to be in web mercator auxiliary sphere

HI, I've was away for a few days. I am not the publisher of the WMS service. Also it seems I can only view the layers if
spatialReference set to wgs84(4326), in this setting I cannot display a world map from ESRI.

This being the case, I have two questions:

Can I convert a wgs84 service to 3857/102100 in the javascript side, or via the url parameters?

Is my only other option to use a proxy

Thanks for the help so far!
Daniel

1. you cannot convert tiled services to a different coordinate system
2. proxy will not help

Basically if you need to use that WMS service, you cannot use ESRI basemaps.

You only option appears to be to find a wkid 4326 basemap. I am not aware of any

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

&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.

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.

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!
