Need help adding a WMTSLayer from service.

[JulieTeal]

Hi guys.

I may be way off base here but I'm trying to add a layer from a WMTS connection. I'm using the .Net SDK (C#).

So far  I can connect to the Server using IWMTSConnection and then create a WMTSLayer with WMTSConnection() but I can only ever use the first WMTSLayer as an ILayer. I can iterate over the whole structure and pull layer descriptions using IWMTSServiceDescription with IWMTSLayerDescription. But Im at a loss creating a connection where I can use a specific LayerName/Identifier.

Is there a way to either specify the LayerName perhaps when creating the IWMTSConnection or creating the WMTSLayer, that will allow me access other WMTSLayers?

Heres a cut down version of what I currently have:

    IWMTSLayer wmtsLayer = new WMTSLayerClass();
    IDataLayer dLayer = new WMTSLayerClass();
   
    IPropertySet propSet = new PropertySetClass();
    propSet.SetProperty("URL", "http://localhost/erdas-iws/ogc/wmts/?Service=WMTS&Request=GetCapabilities");

    IWMTSConnectionFactory wmtsConnFactory = new WMTSConnectionFactoryClass();
    IWMTSConnection wmtsConnection = wmtsConnFactory.Open(propSet, 0, null);

    ESRI.ArcGIS.GISClient.IWMTSServiceDescription wmtsServiceDescription = wmtsConnection as IWMTSServiceDescription;
    wmtsLayer.WMTSConnection(wmtsConnection);
                 
    for (int i = 0; i < wmtsServiceDescription.LayerDescriptionCount; i++)
    {
          IWMTSLayerDescription layerDescription = wmtsServiceDescription.get_LayerDescription(i);
          if (layerDescription.Identifier.Equals(Wmts_Name, StringComparison.InvariantCultureIgnoreCase))
          {
               //We have a match
               //Maybe need something here to open the correct WMTSLayer?
          } 
     }

     if (wmtsLayer != null)
     {
          IMxDocument mxDocument = (IMxDocument)mxApp.Document;
          mxDocument.FocusMap.AddLayer((ILayer)wmtsLayer);
          return true;
     }

Any help on this is greatly appreciate.

Thanks.

It does not seem like it should be rocket surgery to add a WMTS layer into a layer or layer group. Be that as it may, I can find no working c# example or reference to anyone that has successfully accomplished such a feat. Has anyone done this? Can it be done? How? I have successfully displayed a single layer from a WMTS service, but the other layers would be nice to have too. I can't even find a UID for a WMTS layer.

Seems oddly quiet, would appreciate someone who knows speaking up.

I guess the lack of response on this means it isn't possible. Seems strange that WMTS is implemented but is not usable.

Hi,

I reviewed your code and corrected it like below:

public static ILayer GetWMTSLayer(string url = "http://IP-Address:Port/Service/rest/services/OSM/MapServer/WMTS")
        {
            IWMTSLayer wmtsLayer = new WMTSLayerClass(); 

            IPropertySet propSet = new PropertySetClass();
            propSet.SetProperty("URL", url);


            try
            {
                IWMTSConnectionFactory wmtsConnFactory = new WMTSConnectionFactoryClass();
                IWMTSConnection wmtsConnection = wmtsConnFactory.Open(propSet, 0, null);
                var con = wmtsLayer.Connect(wmtsConnection.FullName);


                //ESRI.ArcGIS.GISClient.IWMTSServiceDescription wmtsServiceDescription = wmtsConnection as IWMTSServiceDescription;
                //string layerName = "GoogleMapsRoad",
                //for (int i = 0; i < wmtsServiceDescription.LayerDescriptionCount; i++)
                //{
                //      IWMTSLayerDescription layerDescription = wmtsServiceDescription.get_LayerDescription(i);
                //      if (layerDescription.Identifier.Equals(layerName, StringComparison.InvariantCultureIgnoreCase))
                //      {
                //           //We have a match
                //           //Maybe need something here to open the correct WMTSLayer?
                //      } 
                // }


                if (con)
                    return (ILayer)wmtsLayer;
            }
            catch (COMException ex)
            {
                MessageBox.Show("Couldn't Get the service:" + url);
            }
            catch (Exception ex)
            {
                MessageBox.Show("Couldn't Get the service:" + url);
            }
            return null;
        }

Thanks for your reply but I was already at a point where I could connect to a WMTS service and add a layer. The issue here is retrieving anything other than the first layer.

Hy,

I have the same problem:

  I need to get a specific sublayer of a WMTS-mapservice.

  I'm also getting listed all the sublayers in the IWMTSLayerDescription but can't return a single sublayer as ILayer.

  I'm also always getting the first sublayer from the list returned as ILayer.

Any solution or workaround?

Thanks,

Tom

I am facing similar problem. I want to add all the layers in my WMTS service to ArcMap, but I am able to get only one. Has someone got any solution for this.

Thanks

I got solution for adding all layers at ones, as well as a particular layer to ArcMap:

public static void GetWMTSLayer(string url = "http://IP-Address:Port/Service/rest/services/OSM/MapServer/WMTS")

{

     IProperySet propSet= new PropertySetClass();

     propSet.SetProperty("URL",url);

     IWMTSConnectionFactory wmtsConnFactory=new WMTSConnectionFactoryClass();

     IWMTSConnection wmtsConnection=wmtsConnFactory.Open(propSet,0,null);

     IWMTSServiceDescription wmtsServceDescriotion=wmtsConnection as IWMTSServiceDescription ;

     for(int i=0;i< wmtsServceDescriotion.LayerDescriptionCount;i++)

     {

          IWMTSLayerDescription layerDescription=wmtsServceDescriotion.getLayerDescription(i);

          IWMTSLayer wmtsLayer=new WMTSLayerClass();

          IPropertySet propSet_1=new PropertySetClass();

          propSet_1.SetProperty("URL", url);

          propSet_1.SetProperty("LayerName",layerDescription.Identifier);

          WMTSConnectionName connectonName= new WMTSConnectionNameClass();

          connectionName.ConnectionProperties=propSet_1;

          wmtsLayer.Connect((IName)connectionName);

            addData(wmtslayer);

     }

}

public static void addData(IWMTSLayer wmtslayer)

{

     IMap pMap=(IMap)((IMxDocument)ArcMap.Application.Document).FocusMap);

     ILayer pLayer=new FeatureLayer();

     pLayer=(ILayer)wmtslayer;

     pMap.AddLayer(pLayer);

}
