GoogleEarthEnterpriseMapsProvider

external class GoogleEarthEnterpriseMapsProvider(source)

To construct a GoogleEarthEnterpriseMapsProvider, call [GoogleEarthEnterpriseImageryProvider.fromUrl]. Do not call the constructor directly.

Provides tiled imagery using the Google Earth Imagery API.

Notes: This imagery provider does not work with the public Google Earth servers. It works with the Google Earth Enterprise Server.

By default the Google Earth Enterprise server does not set the
[Cross-Origin Resource Sharing](http://www.w3.org/TR/cors/) headers. You can either
use a proxy server which adds these headers, or in the /opt/google/gehttpd/conf/gehttpd.conf
and add the 'Header set Access-Control-Allow-Origin "*"' option to the '' and
'' directives.

This provider is for use with 2D Maps API as part of Google Earth Enterprise. For 3D Earth API uses, it
is necessary to use [GoogleEarthEnterpriseImageryProvider]

const google = await GoogleEarthEnterpriseMapsProvider.fromUrl("https://earth.localdomain", 1008);

hasAlphaChannel

val 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.

maximumLevel

val maximumLevel: Int?

Gets the maximum level-of-detail that can be requested.

minimumLevel

val minimumLevel: Int

Gets the minimum level-of-detail that can be requested.

path

val path: String

Gets the url path of the data on the Google Earth server.

requestType

val requestType: String

Gets the type of data that is being requested from the provider.

tileDiscardPolicy
