new Cesium.WebMapTileServiceImageryProvider(options)
Scene/WebMapTileServiceImageryProvider.js 139

Provides tiled imagery served by WMTS 1.0.0 compliant servers. This provider supports HTTP KVP-encoded and RESTful GetTile requests, but does not yet support the SOAP encoding.
Name Type Description
options Object Object with the following properties:
Name Type Default Description
url Resource | String The base URL for the WMTS GetTile operation (for KVP-encoded requests) or the tile-URL template (for RESTful requests). The tile-URL template should contain the following variables: {style}, {TileMatrixSet}, {TileMatrix}, {TileRow}, {TileCol}. The first two are optional if actual values are hardcoded or not required by the server. The {s} keyword may be used to specify subdomains.
format String 'image/jpeg' optional The MIME type for images to retrieve from the server.
layer String The layer name for WMTS requests.
style String The style name for WMTS requests.
tileMatrixSetID String The identifier of the TileMatrixSet to use for WMTS requests.
tileMatrixLabels Array optional A list of identifiers in the TileMatrix to use for WMTS requests, one per TileMatrix level.
clock Clock optional A Clock instance that is used when determining the value for the time dimension. Required when options.times is specified.
times TimeIntervalCollection optional TimeIntervalCollection with its data property being an object containing time dynamic dimension and their values.
dimensions Object optional A object containing static dimensions and their values.
tileWidth Number 256 optional The tile width in pixels.
tileHeight Number 256 optional The tile height in pixels.
tilingScheme TilingScheme optional The tiling scheme corresponding to the organization of the tiles in the TileMatrixSet.
rectangle Rectangle Rectangle.MAX_VALUE optional The rectangle covered by the layer.
minimumLevel Number 0 optional The minimum level-of-detail supported by the imagery provider.
maximumLevel Number optional The maximum level-of-detail supported by the imagery provider, or undefined if there is no limit.
ellipsoid Ellipsoid optional The ellipsoid. If not specified, the WGS84 ellipsoid is used.
credit Credit | String optional A credit for the data source, which is displayed on the canvas.
subdomains String | Array.<String> 'abc' optional The subdomains to use for the {s} placeholder in the URL template. If this parameter is a single string, each character in the string is a subdomain. If it is an array, each element in the array is a subdomain.

Members

clock : Clock
Scene/WebMapTileServiceImageryProvider.js 503

Gets or sets a clock that is used to get keep the time used for time dynamic parameters.

readonlycredit : Credit
Scene/WebMapTileServiceImageryProvider.js 477

Gets the credit to display when this imagery provider is active. Typically this is used to credit the source of the imagery. This function should not be called before WebMapTileServiceImageryProvider#ready returns true.

dimensions : Object
Scene/WebMapTileServiceImageryProvider.js 531

Gets or sets an object that contains static dimensions and their values.

readonlyerrorEvent : Event
Scene/WebMapTileServiceImageryProvider.js 430

Gets an event that is raised when the imagery provider encounters an asynchronous error. By subscribing to the event, you will be notified of the error and can potentially recover from it. Event listeners are passed an instance of TileProviderError.

readonlyformat : String
Scene/WebMapTileServiceImageryProvider.js 442

Gets the mime type of images returned by this imagery provider.

readonlyhasAlphaChannel : Boolean
Scene/WebMapTileServiceImageryProvider.js 493

Gets a value indicating whether or not the images provided by this imagery provider include an alpha channel. If this property is false, an alpha channel, if present, will be ignored. If this property is true, any images without an alpha channel will be treated as if their alpha is 1.0 everywhere. When this property is false, memory usage and texture upload time are reduced.

readonlymaximumLevel : Number
Scene/WebMapTileServiceImageryProvider.js 362

Gets the maximum level-of-detail that can be requested. This function should not be called before WebMapTileServiceImageryProvider#ready returns true.

readonlyminimumLevel : Number
Scene/WebMapTileServiceImageryProvider.js 375

Gets the minimum level-of-detail that can be requested. This function should not be called before WebMapTileServiceImageryProvider#ready returns true.

readonlyproxy : Proxy
Scene/WebMapTileServiceImageryProvider.js 323

Gets the proxy used by this provider.

readonlyready : Boolean
Scene/WebMapTileServiceImageryProvider.js 454

Gets a value indicating whether or not the provider is ready for use.

readonlyreadyPromise : Promise.<Boolean>
Scene/WebMapTileServiceImageryProvider.js 464

Gets a promise that resolves to true when the provider is ready for use.

readonlyrectangle : Rectangle
Scene/WebMapTileServiceImageryProvider.js 401

Gets the rectangle, in radians, of the imagery provided by this instance. This function should not be called before WebMapTileServiceImageryProvider#ready returns true.

readonlytileDiscardPolicy : TileDiscardPolicy
Scene/WebMapTileServiceImageryProvider.js 416

Gets the tile discard policy. If not undefined, the discard policy is responsible for filtering out "missing" tiles via its shouldDiscardImage function. If this function returns undefined, no tiles are filtered. This function should not be called before WebMapTileServiceImageryProvider#ready returns true.

readonlytileHeight : Number
Scene/WebMapTileServiceImageryProvider.js 349

Gets the height of each tile, in pixels. This function should not be called before WebMapTileServiceImageryProvider#ready returns true.

Methods

getTileCredits(x, y, level) → Array.<Credit>
Scene/WebMapTileServiceImageryProvider.js 556

Gets the credits to be displayed when a given tile is displayed.
Name Type Description
x Number The tile X coordinate.
y Number The tile Y coordinate.
level Number The tile level;
Returns:
The credits to be displayed when the tile is displayed.
Throws:
  • DeveloperError : getTileCredits must not be called before the imagery provider is ready.

pickFeatures(x, y, level, longitude, latitude) → Promise.<Array.<ImageryLayerFeatureInfo>>|undefined
Scene/WebMapTileServiceImageryProvider.js 613

Picking features is not currently supported by this imagery provider, so this function simply returns undefined.
Name Type Description
x Number The tile X coordinate.
y Number The tile Y coordinate.
level Number The tile level.
longitude Number The longitude at which to pick features.
latitude Number The latitude at which to pick features.
Returns:
A promise for the picked features that will resolve when the asynchronous picking completes. The resolved value is an array of ImageryLayerFeatureInfo instances. The array may be empty if no features are found at the given location. It may also be undefined if picking is not supported.

requestImage(x, y, level, request) → Promise.<(Image|Canvas)>|undefined
Scene/WebMapTileServiceImageryProvider.js 575

Requests the image for a given tile. This function should not be called before WebMapTileServiceImageryProvider#ready returns true.
Name Type Description
x Number The tile X coordinate.
y Number The tile Y coordinate.
level Number The tile level.
request Request optional The request object. Intended for internal use only.
Returns:
A promise for the image that will resolve when the image is available, or undefined if there are too many active requests to the server, and the request should be retried later. The resolved image may be either an Image or a Canvas DOM object.
Throws:
  • DeveloperError : requestImage must not be called before the imagery provider is ready.
