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
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.
readonlycredit : Credit
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
WebMapServiceImageryProvider#ready
returns 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
readonlyerrorEvent : Event
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 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.
Gets the maximum level-of-detail that can be requested. This function should
not be called before
WebMapServiceImageryProvider#ready
returns true.
Gets the minimum level-of-detail that can be requested. This function should
not be called before
WebMapServiceImageryProvider#ready
returns true.
Gets the proxy used by this provider.
Gets a value indicating whether or not the provider is ready for use.
Gets a promise that resolves to true when the provider is ready for use.
readonlyrectangle : Rectangle
Gets the rectangle, in radians, of the imagery provided by this instance. This function should
not be called before
WebMapServiceImageryProvider#ready
returns true.
readonlytileDiscardPolicy : TileDiscardPolicy
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
WebMapServiceImageryProvider#ready
returns true.
Gets the height of each tile, in pixels. This function should
not be called before
WebMapServiceImageryProvider#ready
returns true.
Gets the width of each tile, in pixels. This function should
not be called before
WebMapServiceImageryProvider#ready
returns true.
readonlytilingScheme : TilingScheme
Gets the tiling scheme used by this provider. This function should
not be called before
WebMapServiceImageryProvider#ready
returns true.
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.
Throws:
-
DeveloperError :
getTileCredits
must not be called before the imagery provider is ready.
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. This function should not be called before
ImageryProvider#ready
returns true.
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.
Throws:
-
DeveloperError :
pickFeatures
must not be called before the imagery provider is ready.
Requests the image for a given tile. This function should
not be called before
WebMapServiceImageryProvider#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 :
