To construct a GoogleEarthEnterpriseImageryProvider, call
Provides tiled imagery using the Google Earth Enterprise REST API.
Notes: This provider is for use with the 3D Earth API of Google Earth Enterprise,
GoogleEarthEnterpriseImageryProvider.fromMetadata
. Do not call the constructor directly.
GoogleEarthEnterpriseMapsProvider
should be used with 2D Maps API.

Members
readonly credit : Credit
Gets the credit to display when this imagery provider is active. Typically this is used to credit
the source of the imagery.
The default alpha blending value of this provider, with 0.0 representing fully transparent and
1.0 representing fully opaque.
Deprecated: true
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
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
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
The default gamma correction to apply to this provider. 1.0 uses the unmodified imagery color.
Deprecated: true
The default hue of this provider in radians. 0.0 uses the unmodified imagery color.
Deprecated: true
deprecated defaultMagnificationFilter : TextureMagnificationFilter
The default texture magnification filter to apply to this provider.
Deprecated: true
deprecated defaultMinificationFilter : TextureMinificationFilter
The default texture minification filter to apply to this provider.
Deprecated: true
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
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
readonly errorEvent : 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. Setting this property to false reduces memory usage
and texture upload time.
Gets the maximum level-of-detail that can be requested.
Gets the minimum level-of-detail that can be requested.
readonly proxy : Proxy
Gets the proxy used by this provider.
Gets a value indicating whether or not the provider is ready for use.
Deprecated: true
Gets a promise that resolves to true when the provider is ready for use.
Deprecated: true
readonly rectangle : Rectangle
Gets the rectangle, in radians, of the imagery provided by this instance.
readonly tileDiscardPolicy : 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.
Gets the height of each tile, in pixels.
Gets the width of each tile, in pixels.
readonly tilingScheme : TilingScheme
Gets the tiling scheme used by this provider.
Gets the name of the Google Earth Enterprise server url hosting the imagery.
Methods
static Cesium.GoogleEarthEnterpriseImageryProvider.fromMetadata(metadata, options) → GoogleEarthEnterpriseImageryProvider
Creates a tiled imagery provider using the Google Earth Enterprise REST API.
Name | Type | Description |
---|---|---|
metadata |
GoogleEarthEnterpriseMetadata | A metadata object that can be used to share metadata requests with a GoogleEarthEnterpriseTerrainProvider. |
options |
GoogleEarthEnterpriseImageryProvider.ConstructorOptions | Object describing initialization options. |
Returns:
Throws:
-
RuntimeError : The metadata url does not have imagery
Example:
const geeMetadata = await GoogleEarthEnterpriseMetadata.fromUrl("http://www.example.com");
const gee = Cesium.GoogleEarthEnterpriseImageryProvider.fromMetadata(geeMetadata);
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.
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:
Undefined since picking is not supported.
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.
