Members
readonly availability : TileAvailability
Gets an object that can be used to determine availability of terrain from this provider, such as
at points and in rectangles. This property may be undefined if availability
information is not available.
readonly credit : Credit
Gets the credit to display when this terrain provider is active. Typically this is used to credit
the source of the terrain.
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 requested tiles include vertex normals.
Gets a value indicating whether or not the provider includes a water mask. The water mask
indicates which areas of the globe are water rather than land, so they can be rendered
as a reflective surface with animated waves.
readonly proxy : Proxy
Gets the proxy used by this provider.
readonly tilingScheme : TilingScheme
Gets the tiling scheme used by this provider.
Gets the name of the Google Earth Enterprise server url hosting the imagery.

Gets the maximum geometric error allowed in a tile at a given level.
Name | Type | Description |
---|---|---|
level |
number | The tile level for which to get the maximum geometric error. |
Returns:
The maximum geometric error.
Determines whether data for a tile is available to be loaded.
Name | Type | Description |
---|---|---|
x |
number | The X coordinate of the tile for which to request geometry. |
y |
number | The Y coordinate of the tile for which to request geometry. |
level |
number | The level of the tile for which to request geometry. |
Returns:

number | The level of the tile for which to request geometry. |
Returns:
requestTileGeometry(x, y, level, request) → Promise.<TerrainData>|undefined
Requests the geometry for a given tile. The result must include terrain data and
may optionally include a water mask and an indication of which child tiles are available.
Name | Type | Description |
---|---|---|
x |
number | The X coordinate of the tile for which to request geometry. |
y |
number | The Y coordinate of the tile for which to request geometry. |
level |
