`url`	`string \| null \| undefined`
`version` readonly	`SceneServiceVersion`

copyright

Property

Type: string | null | undefined

The copyright text as defined by the scene service.

layerId

Property

Type: number

The layer ID, or layer index, of a Scene Service layer. This is particularly useful when loading a single layer with the portalItem property from a service containing multiple layers. You can specify this value in one of two scenarios:

When loading the layer via the portalItem property.
When pointing the layer url directly to the Scene Service.

If a layerId is not specified in either of the above scenarios, then the first layer in the service (layerId = 0) is selected.

Examples

// while these examples use a SceneLayer, the same pattern can be
// used for other layers that may be loaded from portalItem ids

// loads the third layer in the given Portal Item
let layer = new SceneLayer({
  portalItem: {
    id: "73df987984b24094b848d580eb83b0fb"
  },
  layerId: 2
});

// If not specified, the first layer (layerId: 0) will be returned
let layer = new SceneLayer({
  portalItem: {
    id: "73df987984b24094b848d580eb83b0fb"
  }
});

// Can also be used if URL points to service and not layer
let layer = new SceneLayer({
  url: "https://scenesampleserverdev.arcgis.com/arcgis/rest/services/Hosted/DevA_Trees/SceneServer",
  layerId: 0  // Notice that the url doesn't end with /2
});

// This code returns the same layer as the previous snippet
let layer = new SceneLayer({
  url: "https://scenesampleserverdev.arcgis.com/arcgis/rest/services/Hosted/DevA_Trees/SceneServer/layers/0",
  // The layer id is specified in the URL
});

spatialReference

autocast Property

Type: SpatialReference

The spatial reference of the layer.

url

Property

Type: string | null | undefined

The URL of the REST endpoint of the layer or scene service. The URL may either point to a resource on ArcGIS Enterprise or ArcGIS Online.

The layer may be specified using the layerId property when the url points directly to a service and not a specific layer. If layerId is not specified, then it will default to the first layer in the service.

Examples

// Layer from Scene Service on ArcGIS Server
let sceneLayer = new SceneLayer({
  url: "https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/Paris_3D_Local_WSL2/SceneServer/layers/0"
});

// Can also be used if URL points to service and not layer
let layer = new SceneLayer({
  // Notice that the url doesn't end with /0
  url: "https://scenesampleserverdev.arcgis.com/arcgis/rest/services/Hosted/DevA_Trees/SceneServer",
  layerId: 0
});

version

readonly Property

Type: SceneServiceVersion

The version of the scene service specification used for this service.

Example

// Prints the version to the console - e.g. 1.4, 1.5, etc.
console.log(layer.version.versionString);
