ArcGISTiledElevationTerrainProvider

new Cesium.ArcGISTiledElevationTerrainProvider(options)
Core/ArcGISTiledElevationTerrainProvider.js 47

A TerrainProvider that produces terrain geometry by tessellating height maps retrieved from Elevation Tiles of an an ArcGIS ImageService.
Name Type Description
options Object Object with the following properties:
Name Type Description
url Resource | String | Promise.<Resource> | Promise.<String> The URL of the ArcGIS ImageServer service.
token String optional The authorization token to use to connect to the service.
ellipsoid Ellipsoid optional The ellipsoid. If the tilingScheme is specified, this parameter is ignored and the tiling scheme's ellipsoid is used instead. If neither parameter is specified, the WGS84 ellipsoid is used.
Example:
const terrainProvider = new Cesium.ArcGISTiledElevationTerrainProvider({
  url : 'https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer',
  token : 'KED1aF_I4UzXOHy3BnhwyBHU4l5oY6rO6walkmHoYqGp4XyIWUd5YZUC1ZrLAzvV40pR6gBXQayh0eFA8m6vPg..'
});
viewer.terrainProvider = terrainProvider;

Members

readonly availability : TileAvailability
Core/ArcGISTiledElevationTerrainProvider.js 310

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 TerrainProvider#ready returns true. This property may be undefined if availability information is not available.

readonly credit : Credit
Core/ArcGISTiledElevationTerrainProvider.js 217

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 ArcGISTiledElevationTerrainProvider#ready returns true.

readonly errorEvent : Event
Core/ArcGISTiledElevationTerrainProvider.js 204

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.

readonly hasVertexNormals : Boolean
Core/ArcGISTiledElevationTerrainProvider.js 296

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

readonly hasWaterMask : Boolean
Core/ArcGISTiledElevationTerrainProvider.js 283

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 ArcGISTiledElevationTerrainProvider#ready returns true.

readonly ready : Boolean
Core/ArcGISTiledElevationTerrainProvider.js 256

Gets a value indicating whether or not the provider is ready for use.

readonly readyPromise : Promise.<Boolean>
Core/ArcGISTiledElevationTerrainProvider.js 268

Gets a promise that resolves to true when the provider is ready for use.

readonly tilingScheme : GeographicTilingScheme
Core/ArcGISTiledElevationTerrainProvider.js 237

Gets the tiling scheme used by this provider. This function should not be called before ArcGISTiledElevationTerrainProvider#ready returns true.

Methods

getLevelMaximumGeometricError(level) → Number
Core/ArcGISTiledElevationTerrainProvider.js 444

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.

getTileDataAvailable(x, y, level) → Boolean|undefined
Core/ArcGISTiledElevationTerrainProvider.js 466

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:
Undefined if not supported, otherwise true or false.

loadTileDataAvailability(x, y, level) → undefined
Core/ArcGISTiledElevationTerrainProvider.js 493

Makes sure we load availability data for a tile
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:
This provider does not support loading availability.

requestTileGeometry(x, y, level, request) → Promise.<TerrainData>|undefined
Core/ArcGISTiledElevationTerrainProvider.js 337

Requests the geometry for a given tile. This function should not be called before ArcGISTiledElevationTerrainProvider#ready returns true. The result includes terrain data and indicates that all 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 Number The level of the tile for which to request geometry.
request Request optional The request object. Intended for internal use only.
Returns:
A promise for the requested geometry. If this method returns undefined instead of a promise, it is an indication that too many requests are already pending and the request will be retried later.
