Detailed Description

An Open Geospatial Consortium (OGC) Web Map Tile Service (WMTS).

The OGC WMTS standard describes an implementation for serving maps using predefined tiles. The WMTS service may be hosted in the cloud on ArcGIS Online, on a third-party server, or on-premises with ArcGIS Server.

The WmtsService is constructed using the URL of the service and once the load task completes (see Loadable) allows the user to browse for predefined content via the serviceInfo.

A WMTS service provides access to a set of cached tiles at predefined scales. The service provides one or more tile matrix sets, each of which which is composed of one or more tile matrices for a series of fixed scales. As the scale descreases, the number of tiles in the matrix increases - each tile being of a smaller geographic area and of a higher resolution.

A WMTS service may also host several layers, each of which can be described by a WmtsLayerInfo.

Example: List the WMTS layers available in a service:

QUrl wmtsUrl("http://sampleserver6.arcgisonline.com/arcgis/rest/services/WorldTimeZones/MapServer/WMTS");
WmtsService* service = new WmtsService(wmtsUrl, parent);

connect(service, &WmtsService::doneLoading, parent, [service, map, parent](Esri::ArcGISRuntime::Error loadError)
{
  if (!loadError.isEmpty())
    qDebug() << loadError.message() << ": " << loadError.additionalMessage();

  if (service->loadStatus() != LoadStatus::Loaded)
    return;

  // get the service info for the service
  WmtsServiceInfo serviceInfo = service->serviceInfo();

  // create a WmtsLayer for each layer in the service
  QList<WmtsLayerInfo> layerInfos = serviceInfo.layerInfos();
  for (const WmtsLayerInfo& layerInfo : layerInfos)
  {
    WmtsLayer* wmtsLayer = new WmtsLayer(layerInfo, parent);
    map->operationalLayers()->append(wmtsLayer);
  }
});

Member Function Documentation

WmtsService::WmtsService(const QUrl &url, QObject *parent = nullptr)

Constructor that accepts a URL (url) and an optional parent.

WmtsService::WmtsService(const QUrl &url, Credential *credential, QObject *parent = nullptr)

Constructor that accepts a URL (url), credential and an optional parent.

  • url. The URL of the WMTS service.
  • credential. The credential.
  • parent. The parent object for this WmtsService (optional).

WmtsService::~WmtsService()

Destructor.

[virtual] void WmtsService::cancelLoad()

Reimplemented from Loadable::cancelLoad().

See Loadable.

[virtual] Credential *WmtsService::credential() const

Reimplemented from RemoteResource::credential().

Returns the security credential used to access this WmtsService.

Only applicable if the service is secured.

QMap<QString, QString> WmtsService::customParameters() const

Returns custom parameters to append to GetCapabilities and GetTile requests.

This function was introduced in Esri::ArcGISRuntime 100.6.

See also setCustomParameters.

[signal] void WmtsService::doneLoading(Esri::ArcGISRuntime::Error loadError)

Signal emitted when this object is done loading.

  • loadError - Details about any error that may have occurred.

Note: If there is a load error it will also be emitted on the errorOccurred signal.

See also Loadable and Object.

[virtual] void WmtsService::load()

Reimplemented from Loadable::load().

See Loadable.

[virtual] Error WmtsService::loadError() const

Reimplemented from Loadable::loadError().

See Loadable.

[virtual] LoadStatus WmtsService::loadStatus() const

Reimplemented from Loadable::loadStatus().

See Loadable.

[signal] void WmtsService::loadStatusChanged(Esri::ArcGISRuntime::LoadStatus loadStatus)

Signal emitted when the load status changes for this object.

See also Loadable.

[virtual] RequestConfiguration WmtsService::requestConfiguration() const

Reimplemented from RemoteResource::requestConfiguration().

Returns the RequestConfiguration in use by this task.

See also setRequestConfiguration().

[virtual] void WmtsService::retryLoad()

Reimplemented from Loadable::retryLoad().

See Loadable.

WmtsServiceInfo WmtsService::serviceInfo() const

Returns the service info for this service.

A WmtsServiceInfo provides the information for browsing and accessing the service contents.

void WmtsService::setCustomParameters(const QMap<QString, QString> &customParameters)

Sets customParameters to append to GetCapabilities and GetTile requests.

If a parameter with the same name is defined in a layer's custom parameters, then layer-specific values take precedence over service-wide values.

Parameters intended for GetCapabilities requests should be set before the service is loaded.

This function was introduced in Esri::ArcGISRuntime 100.6.

See also customParameters().

[virtual] void WmtsService::setRequestConfiguration(const RequestConfiguration &requestConfiguration)

Reimplemented from RemoteResource::setRequestConfiguration().

Sets configuration parameters used for network requests sent by this task to requestConfiguration.

See also requestConfiguration().

[virtual] QUrl WmtsService::url() const

Reimplemented from RemoteResource::url().

Returns the URL of this WmtsService.
