ArcGisImageServerTerrainProvider

ArcGisImageServerTerrainProvider

new

A TerrainProvider that produces terrain geometry by tessellating height maps retrieved from an ArcGIS ImageServer.

Parameters:
Name Type Argument Description
description.url String The URL of the ArcGIS ImageServer service.
description.token String <optional>
 The authorization token to use to connect to the service.
description.proxy Object <optional>
 A proxy to use for requests. This object is expected to have a getURL function which returns the proxied URL, if needed.
description.tilingScheme TilingScheme <optional>
 The tiling scheme specifying how the terrain is broken into tiles. If this parameter is not provided, a GeographicTilingScheme is used.
description.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.
description.credit Credit | String <optional>
 The credit, which will is displayed on the canvas.
Example
var terrainProvider = new Cesium.ArcGisImageServerTerrainProvider({
  url : 'http://elevation.arcgisonline.com/ArcGIS/rest/services/WorldElevation/DTMEllipsoidal/ImageServer',
  token : 'KED1aF_I4UzXOHy3BnhwyBHU4l5oY6rO6walkmHoYqGp4XyIWUd5YZUC1ZrLAzvV40pR6gBXQayh0eFA8m6vPg..',
  proxy : new Cesium.DefaultProxy('/terrain/')
});
centralBody.terrainProvider = terrainProvider;

Methods

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 ArcGisImageServerTerrainProvider#isReady returns true.

Returns:
Credit The credit, or undefined if no credit exists

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.

Returns:
Event The event.

Gets the maximum geometric error allowed in a tile at a given level.

Parameters:
Name Type Description
level Number The tile level for which to get the maximum geometric error.
Returns:
Number The maximum geometric error.

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

Throws:
DeveloperError : getTilingScheme must not be called before the terrain provider is ready.
Returns:
GeographicTilingScheme The tiling scheme.
See:

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.

Returns:
Boolean True if the provider has a water mask; otherwise, false.

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

Returns:
Boolean True if the provider is ready to use; otherwise, false.

Requests the geometry for a given tile. This function should not be called before ArcGisImageServerTerrainProvider#isReady returns true. The result includes terrain data and indicates that all child tiles are available.

Parameters:
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:
Promise | TerrainData 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.
