WmtsLayer Class | ArcGIS Maps SDK for Qt

A layer that can visualize data from a WMTS service by using pre-generated tiles. More...

Web Map Tile Service (WMTS) is an Open Geospatial Consortium (OGC) standard for delivering geographic data via raster tiles. A WMTS layer uses pre-generated tiles to create a map instead of dynamically generating map images.The service may be hosted in ArcGIS Online, in ArcGIS Enterprise, or in a third party 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.

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.

When creating a WmtsLayer, some WMTS services require that you provide a direct URL 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 URL.

WMTS layer consumes raster tiles that were previously rendered and cached 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.

Example: Add a WMTS layer to a map:

QUrl wmtsUrl("http://sampleserver6.arcgisonline.com/arcgis/rest/services/WorldTimeZones/MapServer/WMTS");
QString layerId = "WorldTimeZones";
auto* wmtsLayer = new WmtsLayer(wmtsUrl, layerId, parent);

connect(wmtsLayer, &WmtsLayer::doneLoading, parent, [wmtsLayer](const Esri::ArcGISRuntime::Error& loadError)
        {
          if (!loadError.isEmpty())
          {
            qDebug() << loadError.message() << ": " << loadError.additionalMessage();
          }

          if (wmtsLayer->loadStatus() != LoadStatus::Loaded)
          {
            return;
          }

          // work with WMTS layer here
        });

Map* map = new Map(BasemapStyle::ArcGISImagery, parent);
map->operationalLayers()->append(wmtsLayer);

Destructor.

Returns the dictionary of custom parameters to be sent with WMTS requests issued by this layer.

These parameters are appended to GetMap and GetFeatureInfo requests. If a parameter with the same name is defined in WmtsService::customParameters, then layer-specific values take precedence over service-wide values.

This function was introduced in Esri::ArcGISRuntime 100.6.

See also setCustomParameters().

Returns the WMTS Layer information.

Returns the preferred image format used for tiles of this WMTS layer.

If an image format is not specified when creating this layer, then the value is TileImageFormat::Unknown until the layer is loaded.

Sets the customParameters to customParameters.

This function was introduced in Esri::ArcGISRuntime 100.6.

See also customParameters.

Returns the WMTS tile matrix set for this WMTS layer.

If tile matrix set is not specified when creating this layer, or is specified only by name, then the value is empty until the layer is loaded.

Returns the tile matrix set identifier for this WMTS layer.

If tile matrix set is not specified when creating this layer, or is specified only by name, then the value is empty until layer is loaded.

Reimplements: RemoteResource::url() const.

Returns the URL of the WMTS service.

This property is assigned a value when the layer is created. However, if the layer is created from a PortalItem, the property will be empty until the layer is loaded.

This value cannot be changed on loaded layers, or on layers created from a WmtsLayerInfo.

{WmtsLayer(const QUrl&, const QString&, QObject*)}

See also Esri::ArcGISRuntime::WmtsLayer::WmtsLayer(const QUrl&, const QString&, QObject*).

Returns the id of the WMTS layer.

layerId cannot be changed on loaded layers, or on layers created from a WmtsLayerInfo.
