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 function should not be called before
MapGISTerrainProvider#ready
returns true. This property may be undefined if availability
information is not available.
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
MapGISTerrainProvider#ready
returns true.
errorEvent : Event
Gets an event that is raised when the terrain 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 metadata.
This function should not be called before
MapGISTerrainProvider#ready
returns true.
Gets a value indicating whether or not the requested tiles include vertex normals.
This function should not be called before
MapGISTerrainProvider#ready
returns true.
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
MapGISTerrainProvider#ready
returns true.
获取地形范围
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.
Boolean flag that indicates if the client should request metadata from the server.
Metadata is appended to the standard tile mesh data only if the client requests the metadata and
if the server provides a metadata.
Boolean flag that indicates if the client should request vertex normals from the server.
Vertex normals data is appended to the standard tile mesh data only if the client requests the vertex normals and
if the server provides vertex normals.
Boolean flag that indicates if the client should request a watermask from the server.
Watermask data is appended to the standard tile mesh data only if the client requests the watermask and
if the server provides a watermask.
是否显示地形
是否显示裙边(只有MapGIS的地形可以设置)
获取地形色表信息
获取地形色表最大高程
获取地形色表最小高程
Gets the tiling scheme used by this provider. This function should
not be called before
MapGISTerrainProvider#ready
returns true.
