static constant Cesium.WebMapServiceImageryProvider.DefaultParameters : object

The default parameters to include in the WMS URL to obtain images. The values are as follows: service=WMS version=1.1.1 request=GetMap styles= format=image/jpeg

static constant Cesium.WebMapServiceImageryProvider.GetFeatureInfoDefaultParameters : object

The default parameters to include in the WMS URL to get feature information. The values are as follows: service=WMS version=1.1.1 request=GetFeatureInfo
Gets or sets a clock that is used to get keep the time used for time dynamic parameters.
Gets the credit to display when this imagery provider is active. Typically this is used to credit the source of the imagery.

deprecated defaultAlpha : Number|undefined

The default alpha blending value of this provider, with 0.0 representing fully transparent and 1.0 representing fully opaque.

Deprecated: true

deprecated defaultBrightness : Number|undefined

The default brightness of this provider. 1.0 uses the unmodified imagery color. Less than 1.0 makes the imagery darker while greater than 1.0 makes it brighter.

Deprecated: true

deprecated defaultContrast : Number|undefined

The default contrast of this provider. 1.0 uses the unmodified imagery color. Less than 1.0 reduces the contrast while greater than 1.0 increases it.

Deprecated: true

deprecated defaultDayAlpha : Number|undefined

The default alpha blending value on the day side of the globe of this provider, with 0.0 representing fully transparent and 1.0 representing fully opaque.

Deprecated: true

deprecated defaultGamma : Number|undefined

The default gamma correction to apply to this provider. 1.0 uses the unmodified imagery color.

Deprecated: true

deprecated defaultHue : Number|undefined

The default hue of this provider in radians. 0.0 uses the unmodified imagery color.

Deprecated: true

The default texture magnification filter to apply to this provider.

Deprecated: true

The default texture minification filter to apply to this provider.

Deprecated: true

deprecated defaultNightAlpha : Number|undefined

The default alpha blending value on the night side of the globe of this provider, with 0.0 representing fully transparent and 1.0 representing fully opaque.

Deprecated: true

deprecated defaultSaturation : Number|undefined

The default saturation of this provider. 1.0 uses the unmodified imagery color. Less than 1.0 reduces the saturation while greater than 1.0 increases it.

Deprecated: true

Gets or sets a value indicating whether feature picking is enabled. If true, WebMapServiceImageryProvider#pickFeatures will invoke the GetFeatureInfo service on the WMS server and attempt to interpret the features included in the response. If false, WebMapServiceImageryProvider#pickFeatures will immediately return undefined (indicating no pickable features) without communicating with the server. Set this property to false if you know your data source does not support picking features or if you don't want this provider's features to be pickable.
Default Value: true
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.
Gets the getFeatureInfo URL of the WMS server.

readonly hasAlphaChannel : boolean

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.
Gets the names of the WMS layers, separated by commas.

readonly maximumLevel : number|undefined

Gets the maximum level-of-detail that can be requested.
Gets the minimum level-of-detail that can be requested.
Gets the proxy used by this provider.

readonly deprecated ready : boolean

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

Deprecated: true

readonly deprecated readyPromise : Promise.<boolean>

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

Deprecated: true

Gets the rectangle, in radians, of the imagery provided by this instance.
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.
Gets the height of each tile, in pixels.
Gets the width of each tile, in pixels.
Gets the tiling scheme used by this provider.
Gets or sets a time interval collection that is used to get time dynamic parameters. The data of each TimeInterval is an object containing the keys and values of the properties that are used during tile requests.
Gets the URL of the WMS server.

Methods

getTileCredits(x, y, level)Array.<Credit>

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.

pickFeatures(x, y, level, longitude, latitude)Promise.<Array.<ImageryLayerFeatureInfo>>|undefined

Asynchronously determines what features, if any, are located at a given longitude and latitude within a tile.
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.

requestImage(x, y, level, request)Promise.<ImageryTypes>|undefined

Requests the image for a given tile.
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.

Type Definitions

Cesium.WebMapServiceImageryProvider.ConstructorOptions

Initialization options for the WebMapServiceImageryProvider constructor
Properties:
Name Type Attributes Default Description
url Resource | string The URL of the WMS service. The URL supports the same keywords as the UrlTemplateImageryProvider.
layers string The layers to include, separated by commas.
parameters object <optional>
WebMapServiceImageryProvider.DefaultParameters Additional parameters to pass to the WMS server in the GetMap URL.
getFeatureInfoParameters object <optional>
WebMapServiceImageryProvider.GetFeatureInfoDefaultParameters Additional parameters to pass to the WMS server in the GetFeatureInfo URL.
enablePickFeatures boolean <optional>
true If true, WebMapServiceImageryProvider#pickFeatures will invoke the GetFeatureInfo operation on the WMS server and return the features included in the response. If false, WebMapServiceImageryProvider#pickFeatures will immediately return undefined (indicating no pickable features) without communicating with the server. Set this property to false if you know your WMS server does not support GetFeatureInfo or if you don't want this provider's features to be pickable. Note that this can be dynamically overridden by modifying the WebMapServiceImageryProvider#enablePickFeatures property.
getFeatureInfoFormats Array.<GetFeatureInfoFormat> <optional>
WebMapServiceImageryProvider.DefaultGetFeatureInfoFormats The formats in which to try WMS GetFeatureInfo requests.
rectangle Rectangle <optional>
Rectangle.MAX_VALUE The rectangle of the layer.
tilingScheme TilingScheme <optional>
new GeographicTilingScheme() The tiling scheme to use to divide the world into tiles.
ellipsoid Ellipsoid <optional>
The ellipsoid. If the tilingScheme is specified, this parameter is ignored and the tiling scheme's ellipsoid is used instead. If neither parameter is specified, the WGS84 ellipsoid is used.
tileWidth number <optional>
256 The width of each tile in pixels.
tileHeight number <optional>
256 The height of each tile in pixels.
minimumLevel number <optional>
0 The minimum level-of-detail supported by the imagery provider. Take care when specifying this that the number of tiles at the minimum level is small, such as four or less. A larger number is likely to result in rendering problems.
maximumLevel number <optional>
The maximum level-of-detail supported by the imagery provider, or undefined if there is no limit. If not specified, there is no limit.
crs string <optional>
CRS specification, for use with WMS specification >= 1.3.0.

SRS specification, for use with WMS specification 1.1.0 or 1.1.1
credit Credit | string <optional>
A credit for the data source, which is displayed on the canvas.
subdomains string | Array.<string> <optional>
'abc' 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.
clock Clock <optional>
A Clock instance that is used when determining the value for the time dimension. Required when `times` is specified.
times TimeIntervalCollection <optional>
TimeIntervalCollection with its data property being an object containing time dynamic dimension and their values.
