WmtsLayer Class
Members  Example  See Also 
ESRI.ArcGIS.Client.Toolkit.DataSources Namespace : WmtsLayer Class

A layer that conforms to the Web Map Tiling Service (WMTS) Open GIS Consortium (OGC) standard. WMTS is a cached service that accesses pre-created tiles from a cache on a server’s hard drive instead of dynamically rendering images.

Remarks

The full WMTS standard can be found on the OpenGIS Web Map Tile Service Implementation Standard web page. As of ArcGIS Server version 10.1 serving WMTS layers as a native REST service is supported.

In order to consume a WmtsLayer successfully the following Properties must be set:

  • Url (The WMTS service endpoint.)
  • ServiceMode (The WMTS service communication protocol.)

There are however several other optional Properties/Methods/Events that should also be set in order to avoid problems consuming a WmtsLayer, they are:

  • Initialized Method (Method raised when WmtsLayer is being created on the client; useful to get or change information about the layer.)
  • InitializationFailed Event (Method raised if the WmtsLayer has a problem being created.)
  • ProxyUrl Property (A proxy service to broker web requests between the WMTS service and the web client.)
  • Layer Property (Name of a single layer in a WMTS service; there can be multiple layers per service.)
  • ID Property (The unique ID of the layer in the Map control.)

A single WMTS service can have multiple layers. For each WmtsLayer instance, only one layer is drawn at a time. In order to discover what layers are available in a WMTS service, append the string '?request=GetCapabilities&service=WMTS&version=1.0.0' to what would be supplied for the WmtsLayer.Url Property in the address bar of a web browser and the full details will be provided in an XML document. A few example strings of obtaining the capabilities of a WMTS service are:

  • http://v2.suite.opengeo.org/geoserver/gwc/service/wmts?request=GetCapabilities&service=WMTS&version=1.0.0
  • http://MyTestServer:6080/arcgis/rest/services/cachedservices/MyTestWMTSService/MapServer/WMTS?request=GetCapabilities&service=WMTS&version=1.0.0

By default if the WmtsLayer.Layer Property is not specified, the first layer respecting the WmtsLayer.TileMatrixSet will be used. When specifying the WmtsLayer.Layer Property at runtime in the code-behind, the WmtsLayer’s Refresh Method fires which in turn invokes the WmtsLayer’s Initialized Event which will cause a re-draw of the layer in the Map Control.

It is important to specify the correct WmtsLayer.WmtsServiceMode Enumeration in the WmtsLayer.ServiceMode Property or the WmtsLayer may not be created properly. The two available WmtsLayer.WmtsServiceMode Enumeration options available are KVP and RESTful. WMTS services provided by ArcGIS Server produce RESTful WmtsLayer.WmtsServiceMode services. The KVP WmtsLayer.WmtsServiceMode means HTTP 'Key/Value Pair' encoding; details on this OGC specification can found by downloading the WCS Extension -- KVP Protocol document.

A call to the WmtsLayer is Asynchronous. As a result, this means that you cannot obtain valid Read (VB.NET) or get (C#) Property values until information has been returned from a WMTS server to the Client application. You can safely obtain valid Read/get Property information in the Initialized, PropertyChanged, TileLoaded, and TileLoading Events or from a function/sub/method that occurs after these Events fire. If you try to obtain Read/get Property information before these Events fire you will obtain invalid or null/Nothing information for the particular Property in question.

Example

How to use:

Select a layer name in the ListBox and click the 'Get WMTSLayer information' button to display various WMTSLayer and WMTSLayer.LayerInfo Property information. The Map will automatically zoom to the Extent of the layer. Properties with the words '[Count]' gives the count of the number of items in an IEnumerable; more coding could be done in the code-behind to dig deeper into the collection.

The XAML code in this example is used in conjunction with the code-behind (C# or VB.NET) to demonstrate the functionality.

The following screen shot corresponds to the code example in this page.

        Add a sample WmtsLayer. Setting the 'ID' Property is good if you want to access the WmtsLayer in code-behind.
        It is mandatory that you set the correct 'ServiceMode' Property. Setting the 'InitializationFailed' Event is useful
        to troubleshoot if the WmtsLayer fails to load. A 'ProxyUrl' is needed to test this particular service; it is not
        always necessary depending on your configuration (i.e. local web service internal to your network). Use the 
        'Initialized' Method to gain access to various Properties/Methods of the WmtsLayer.
