readonly availability : TileAvailability
Core/GoogleEarthEnterpriseTerrainProvider.js 313

Gets an object that can be used to determine availability of terrain from this provider, such as at points and in rectangles. This function should not be called before GoogleEarthEnterpriseTerrainProvider#ready returns true. This property may be undefined if availability information is not available.

readonly credit : Credit
Core/GoogleEarthEnterpriseTerrainProvider.js 270

Gets the credit to display when this terrain provider is active. Typically this is used to credit the source of the terrain. This function should not be called before GoogleEarthEnterpriseTerrainProvider#ready returns true.

readonly errorEvent : Event
Core/GoogleEarthEnterpriseTerrainProvider.js 233

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.

readonly hasVertexNormals : Boolean
Core/GoogleEarthEnterpriseTerrainProvider.js 298

Gets a value indicating whether or not the requested tiles include vertex normals. This function should not be called before GoogleEarthEnterpriseTerrainProvider#ready returns true.

readonly hasWaterMask : Boolean
Core/GoogleEarthEnterpriseTerrainProvider.js 285

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. This function should not be called before GoogleEarthEnterpriseTerrainProvider#ready returns true.
