Wmts Layer
Displays data from a WMTS service by using pre-generated tiles. Web Map Tile Service (WMTS) is an Open Geospatial Consortium (OGC) standard for delivering geographic data via raster tiles. The service may be hosted in the cloud on ArcGIS Online, on a third party server, or on-premises with ArcGIS Server. This API supports WMTS 1.0.0.
A WMTS layer uses pre-generated tiles to create a map instead of dynamically generating map images.
Functional characteristics The maps provided by a WMTS service use predefined symbology defined by the server. As a result, it is not possible to apply custom renderers or to visualize feature selection.
A WMTS service can contain multiple layers in a hierarchy. A WMTS layer can be constructed directly with a URL to a service and the uniquely identifying name of the desired layer. Alternatively, a WMTS service can be used to programmatically explore the available layers and allow the user to choose layers at run time.
Performance characteristics WMTS layer consumes raster tiles that were prerendered by a server. WMTS requires fewer server resources than WMS because the images are rendered and cached ahead of time. WMTS layer requires a connection to the service at all times.
Creating a WMTS layer from URL For some WMTS services it may be necessary to provide a direct URI to the getCapabilities resource, by appending either /1.0.0/WMTSCapabilities.xml or ?service=wmts&request=getCapabilities&version=1.0.0 to the root WMTS URI.

Constructors
Creates a WMTS layer object from a WMTS layer info.
Properties
These parameters are appended to GetTile requests. If a parameter with the same name is defined in the service's custom parameters, then layer-specific values take precedence over service-wide values. WmtsLayer.customParameters property will take precedence over WmtsService.customParameters.
Inherited properties
The unique identifying string for the layer, for example specified in a map or scene. The id is used by other parts of this API to refer to a specific Layer, such as in a set of FeatureFenceParameters or a FacilityLayerDefinition. If not supplied, all layers will be assigned a unique id when created.
Functions
Inherited functions
Cancels loading metadata for the Loadable object.
Fetches the list of legend info.
Returns the layer content's effective visibility at the specified scale. Returns the effective layer content visibility. This effective visibility takes care of the effective visibility of the parents at the specified scale. Will return false if an error occurs.
