Since
ArcGIS Maps SDK for JavaScript 4.0

The web scene is the core element of 3D mapping across ArcGIS. It defines the content, style, environment, and slides of your scene and it can be shared across multiple ArcGIS web and desktop applications. Web scenes can be created, published, and consumed in ArcGIS Pro and ArcGIS Online with the Scene Viewer. The web scene is saved as a JSON document that can be consumed by the ArcGIS Maps SDK for JavaScript via the WebScene class to easily create compelling 3D applications. The JSON document is written according to the web scene specification.

Although you can easily create your own scenes, there are thousands of publicly available web scenes in ArcGIS Online that you can use to get started with the API. You may modify or add new content to these scenes.

To load a WebScene into a SceneView, you need to simply reference the ID of the web scene item in ArcGIS Online via the portalItem property of this class.

const scene = new WebScene({
portalItem: { // autocasts as new PortalItem()
id: "affa021c51944b5694132b2d61fe1057" // ID of the WebScene on arcgis.com
}
});

To load a WebScene from an on-premise portal, set the portal url in esriConfig.portalurl.

esriConfig.portalUrl = "https://myHostName.esri.com/arcgis";
const scene = new WebScene({
portalItem: { // autocasts as new PortalItem()
id: "0614ea1f9dd043e9ba157b9c20d3c538" // ID of the WebScene on the on-premise portal
}
});

Then you must reference the WebScene instance in the SceneView.map property of a SceneView.

const view = new SceneView({
map: scene, // The WebScene instance created above
container: "viewDiv"
});

This will start loading all layers and scene options into the 3D SceneView. The when() method on the WebScene instance can be called to execute processes that may only run after the WebScene is loaded.

scene.when(function() {
// All layers and the basemap have been created
});
view.when(function() {
// All layer and basemap resources have been loaded and are ready to be displayed
});

webscene

The WebScene defines the content of your scene and how the scene looks when it is loaded in your application. There are several common properties of a web scene that you will likely interact with when using this class:

For more information on properties of a web scene, please consult the web scene specification.

There are two types of web scenes: global or local. Global scenes render the earth as a sphere while Local scenes render the earth on a flat plane. Global web scenes can be created with a WebMercator, WGS84, CGCS2000, Mars_2000_(Sphere), GCS_Mars_2000 and GCS_Moon_2000. Local web scenes can be created with WGS84, CGCS2000 or any projected coordinate system. Read the ArcGIS Online help to learn more about choosing global or local scenes.

Slides store a snapshot of a visualization state of the scene that can be re-applied to the scene at a later time. Slides contain properties for viewpoint, layer visibilities, basemap and environment (as well as a title and thumbnail) so that users of a 3D application can easily navigate the scene and accurately recreate a stored view of that scene.

Web scenes can be saved to ArcGIS Online or Portal using saveAs() or save(). Define the portal and once it is loaded, save the web scene.

const portal = new Portal({
url: "https://myportal.arcgis.com/", // the url of the portal
authMode: "immediate" // user authenticates by signing in when the Portal is loaded
});
// once the portal is loaded save the web scene to the portal as a new web scene
portal.load().then(function() {
webscene.saveAs({
title: "My Scene",
portal: portal
})
.then(function() {
console.log("Scene was saved");
})
.catch(function(err) {
console.log(err);
});
})

It's important to note that GraphicsLayer, ImageryLayer, MediaLayer and StreamLayer can't be saved to a web scene. A cached image service can be saved to a web scene, by declaring it as a TileLayer. An OpenStreetMapLayer can be saved as a baseLayer. For more information on types of layers that can be saved in a web scene, see the web scene specification.

Any properties can be set, retrieved or listened to. See the Watch for changes topic.

version

readonlystatic Property
Type
string

The latest supported webscene spec version.

allLayers

readonlyinherited Property
Type
ReadonlyCollection<Layer>
Inherited from: Map

A flattened collection of all layers in the map. This collection contains basemap layers, operational layers and ground layers. Group Layers and their children layers are also part of this collection. Reference layers in the basemap will always be included at the end of the collection.

Layers should not be added directly to this collection. They must only be added via the layers, basemap or ground properties.

To access a flattened collection of tables, use the allTables property instead.

Example
// Find a layer with title "US Counties"
const foundLayer = map.allLayers.find(function(layer) {
return layer.title === "US Counties";
});
// Create a filtered collection of the non-group layers
const nonGroupLayers = map.allLayers.filter(function(layer) {
return !foundLayer.layers;
});
// Listen for any layer being added or removed in the Map
map.allLayers.on("change", function(event) {
console.log("Layer added: ", event.added);
console.log("Layer removed: ", event.removed);
console.log("Layer moved: ", event.moved);
});
// Watching for changes to the visible layers in the Map
reactiveUtils.watch(
() => view.map.allLayers.filter((layer) => layer.visible),
(newVisibleLayers, oldVisibleLayers) => {
const added = newVisibleLayers.filter(
(layer) => !oldVisibleLayers.includes(layer)
);
const removed = oldVisibleLayers.filter(
(layer) => !newVisibleLayers.includes(layer)
);
added.forEach((layer) => console.log(layer.title, "is visible"));
removed.forEach((layer) => console.log(layer.title, "is not visible"));
}
);

allTables

readonlyinherited Property
Type
ReadonlyCollection<Layer>
Inherited from: Map
Since
ArcGIS Maps SDK for JavaScript 4.17

A flattened collection of tables anywhere in the map's hierarchy. This will contain individual tables within the map's tables, in addition to any group layer tables. In order for the table(s) to be recognized as such, the FeatureLayer.isTable property must return true.

Currently, only feature layer tables are recognized. To access spatial layers, use the allLayers property instead.

Example
// A feature layer where isTable = true.
const foundTable = map.allTables.find(function(table) {
// Find a table with title "US Counties"
return table.title === "US Counties";
});

The basemap can be created in a variety of ways:

  1. From the basemap styles service (v2)
  2. From an instance of the Basemap class
  3. From a basemap id

Use of these basemaps requires either an ArcGIS Location Platform account, ArcGIS Online organizational subscription, or an ArcGIS Enterprise license.

To authenticate basemap requests, you may need an access token. You can use an API key or OAuth 2.0. When using an API key, the key must have privileges to access the appropriate location service.

ground

autocast inherited Property
Type
Ground
Inherited from: Map

Specifies the surface properties for the map. In MapView, this property is used by the ElevationProfileAnalysis when the profile contains an ElevationProfileLineGround. In 3D SceneView, it renders the terrain or topographical variations in the real world on the map's surface with a collection of ElevationLayers.

This value can be an instance of Ground, or one of the following strings:

  • world-elevation for a default instance of ground using the Terrain3D Service.
  • world-topobathymetry for an instance of ground that combines surface elevation and bathymetry using the TopoBathy3D Service.

The ground may not be set to null or undefined, it is guaranteed to always contain an instance of type Ground. The elevation can be removed from the ground by setting the ground property to a new empty Ground instance or by removing all the ground layers.

See also
Examples
// Use the world elevation service
const map = new Map({
basemap: "topo-vector",
ground: "world-elevation"
});
// Create a map with the world elevation layer overlaid by a custom elevation layer
const worldElevation = new ElevationLayer({
url: "//elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer"
});
const customElevation = new ElevationLayer({
url: "https://my.server.com/arcgis/rest/service/MyElevationService/ImageServer"
});
const map = new Map({
basemap: "topo-vector",
ground: new Ground({
layers: [ worldElevation, customElevation ]
})
});

heightModelInfo

autocast Property
Type
HeightModelInfo | null | undefined
Since
ArcGIS Maps SDK for JavaScript 4.5

The height model info of the WebScene. This object defines the characteristics of the vertical coordinate system used by the scene. In a SceneView, the height model info is used to avoid combining layers that have incompatible vertical coordinate systems.

initialViewProperties

autocast Property
Type
InitialViewProperties

The initial view of the WebScene. This object may contain the following properties: InitialViewProperties.environment, InitialViewProperties.spatialReference, InitialViewProperties.viewingMode, and InitialViewProperties.viewpoint.

These properties will be applied to the SceneView when the scene loads.

layers

autocast inherited Property
Type
Collection<Layer>
Inherited from: LayersMixin

A collection of operational layers. This property contains the operational layers, such as FeatureLayers, WebTileLayers and GraphicsLayers that may be queried, assigned different renderers, analyzed, etc. It does not include basemaps.

A Layer is a collection of one or more features, or graphics, that represent real-world phenomena. Each feature contains a Symbol and geographic data that allows it to be rendered on the map as a graphic with spatial context. Features within the layer may also contain data attributes that provide additional information that may be viewed in popup windows and used for rendering the layer.

Layers may be added in the constructor, with the add() or addMany() methods, or directly to the layers collection using Collection.add() or Collection.addMany().

In 3D, for layers that are rendered on the terrain, the order of the layers also depends on the type of layer. Tiled layers (BaseTileLayer, ImageryTileLayer, OpenStreetMapLayer, TileLayer, VectorTileLayer, WCSLayer, WebTileLayer and WMTSLayer) are always drawn first in the same order as specified in the layer collection. Dynamic layers (MapImageLayer, ImageryLayer, WMSLayer, and feature based layers with elevation mode on-the-ground) are rendered on top using the order from the layer collection.

A Layer may only be added to one parent. Adding the same layer to multiple Maps or GroupLayers is not possible. If you attempt to do so, the layer will automatically be removed from its current parent and placed in the new parent.

let layer = new GraphicsLayer();
// The layer belongs to map1
map1.layers.add(layer);
// The layer now belongs to map2
// and implicitly does: map1.layers.remove(layer)
map2.layers.add(layer);

To access tables from feature layers, use the tables property in either Map.tables or WebMap.tables classes.

Example
// Add layers in the constructor of Map using an array
let fl = new FeatureLayer(url);
let gl = new GraphicsLayer();
let map = new Map({
layers: [fl, gl]
});
// Add layers using add()
map.addMany([fl, gl]);
// Add layers using layers collection
map.layers.addMany([fl, gl]);
// Add layers using layers collection's push method
map.layers.push(fl, gl);

loaded

readonly Property
Type
boolean

Indicates whether the instance has loaded. When true, the properties of the object can be accessed. A WebScene is considered loaded when its layers and basemap are fully created, but not yet loaded.

Default value
false

loadError

readonlyinherited Property
Type
EsriError | null | undefined
Inherited from: LoadableMixin

The Error object returned if an error occurred while loading.

loadStatus

readonlyinherited Property
Type
"not-loaded" | "loading" | "failed" | "loaded"
Inherited from: LoadableMixin

tables

autocast inherited Property
Type
Collection<Layer>
Inherited from: TablesMixin

A collection of Layer instances that are tables saved in a Map and/or a WebMap. In order for the table(s) to be recognized as such, the FeatureLayer's FeatureLayer.isTable property must return true. A table can be created via one of the options below:

  • Referencing the URL to a table in a feature service.
  • Create a feature layer using the Layer.fromArcGISServerUrl() method and confirm that it is a table using feature layer's FeatureLayer.isTable property. This can be either a feature service or feature collection.
  • Create a feature layer using the Layer.fromPortalItem() method and confirm that it is a table using feature layer's FeatureLayer.isTable property. This can be either a feature service or feature collection.
  • Create an in-memory, non-spatial, client-side feature layer.

Beginning with 4.17, it is possible to persist non-spatial, tables in a feature service to a WebMap, although in-memory (feature collection) tables are not yet supported.

Persisting tables within a GroupLayer.tables is not yet supported. If this is needed, add them to the Map.tables and/or WebMap.tables.

Currently, only feature service feature layers are recognized. To access spatial layers, use the layers property in either Map.layers or WebMap.layers classes

fromJSON

static Method
Signature
fromJSON (json: any): WebScene

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. If the WebScene is used outside of a view, you must call load() explicitly to interact with its resources. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

isRejected() may be used to verify if creating an instance of the class is rejected. If it is rejected, true will be returned.

Returns
boolean

Indicates whether creating an instance of the class has been rejected.

isResolved

inherited Method
Signature
isResolved (): boolean
Inherited from: EsriPromiseMixin

isResolved() may be used to verify if creating an instance of the class is resolved. If it is resolved, true will be returned.

Returns
boolean

Indicates whether creating an instance of the class has been resolved.

load

Method
Signature
load (options?: AbortOptions | null | undefined): Promise<this>

Triggers the loading of the WebScene instance.

A WebScene is considered loaded when its operational layers, basemap and ground are fully created. When created with a portalItem, load() will first fetch its data to create the content, otherwise it resolves immediately.

The SceneView automatically calls the load() method when a WebScene instance is added to its SceneView.map property so it can display in the view and load each individual layer. If the WebScene is used outside of a view, for example to preload it, you must call load() explicitly to interact with its resources.

See also
Parameters
ParameterTypeDescriptionRequired
options

Additional options.

Returns
Promise<this>

Resolves when the WebScene is loaded.

Example
// programmatically load all the layers
const WebScene = await $arcgis.import("@arcgis/core/WebScene.js");
const scene = new WebScene({
portalItem: {
id: "affa021c51944b5694132b2d61fe1057"
}
});
scene.load()
.then(function() {
// load the basemap to get its layers created
return scene.basemap.load();
})
.then(function() {
// grab all the layers and load them
const allLayers = scene.allLayers;
const promises = allLayers.map(function(layer) {
return layer.load();
});
return Promise.all(promises.toArray());
})
.then(function(layers) {
// each layer load promise resolves with the layer
console.log("all " + layers.length + " layers loaded");
})
.catch(function(error) {
console.error(error);
});

loadAll

Method
Signature
loadAll (): Promise<this>
Since
ArcGIS Maps SDK for JavaScript 4.9

Loads all the externally loadable resources associated with the webscene. For the webscene this will load the ground, basemap, layers and slide basemaps.

See also
Returns
Promise<this>

Resolves when all the loadable resources have been loaded. Rejects if at least one of the loadable resources failed to load.

Example
// Load all resources but ignore if one or more of them failed to load
webscene.loadAll()
.catch(function(error) {
// Ignore any failed resources
})
.then(function() {
console.log("All loaded");
});

on

inherited Method
Signature
on <Type extends EventNames<this>>(type: Type, listener: EventedCallback<this["@eventTypes"][Type]>): ResourceHandle
Type parameters
<Type extends EventNames<this>>
Inherited from: EventedMixin

Registers an event handler on the instance. Call this method to hook an event with a listener.

Parameters
ParameterTypeDescriptionRequired
type
Type

An event or an array of events to listen for.

listener
EventedCallback<this["@eventTypes"][Type]>

The function to call when the event fires.

Returns
ResourceHandle

Returns an event handler with a remove() method that should be called to stop listening for the event(s).

PropertyTypeDescription
removeFunctionWhen called, removes the listener from the event.
Example
view.on("click", function(event){
// event is the event handle returned after the event fires.
console.log(event.mapPoint);
});

remove

inherited Method
Signature
remove (layer: Layer): Layer | null | undefined
Inherited from: LayersMixin

Removes the specified layer from the layers collection. The Collection.@before-changes, Collection.@before-remove, Collection.@after-remove, Collection.@after-changes and Collection.@change events will be emitted when this method is called.

Parameters
ParameterTypeDescriptionRequired
layer

Layer to remove from the layers collection.

Returns
Layer | null | undefined

Returns the layer removed from the layers collection.

removeAll

inherited Method
Signature
removeAll (): Layer[]
Inherited from: LayersMixin

Removes all layers. The Collection.@before-changes, Collection.@before-remove, Collection.@after-remove, Collection.@after-changes and Collection.@change events will be emitted when this method is called.

Returns
Layer[]

Returns the layers removed from the layers collection.

removeMany

inherited Method
Signature
removeMany (layers: Layer[]): Layer[]
Inherited from: LayersMixin

Removes the specified layers. The Collection.@before-changes, Collection.@before-remove, Collection.@after-remove, Collection.@after-changes and Collection.@change events will be emitted when this method is called.

Parameters
ParameterTypeDescriptionRequired
layers
Layer[]

Array of layers to remove from the layers collection.

Returns
Layer[]

Returns the layers removed from the layers collection.

reorder

inherited Method
Signature
reorder (layer: Layer, index?: number): Layer | null | undefined
Inherited from: LayersMixin

Changes the layer order. The first layer added is always the base layer, even if its order is changed. The Collection.@change event will be emitted when this method is called.

In 3D, for layers that are rendered on the terrain, the order of the layers also depends on the type of layer. Tiled layers (BaseTileLayer, ImageryTileLayer, OpenStreetMapLayer, TileLayer, VectorTileLayer, WCSLayer, WebTileLayer and WMTSLayer) are always drawn first in the same order as specified in the layer collection. Dynamic layers (MapImageLayer, ImageryLayer, WMSLayer, and feature based layers with elevation mode on-the-ground) are rendered on top using the order from the layer collection.

Parameters
ParameterTypeDescriptionRequired
layer

The layer to be moved.

index

The index location for placing the layer. The bottom-most layer has an index of 0.

Returns
Layer | null | undefined

Returns the layer that was moved.

save

Method
Signature
save (options?: SaveOptions): Promise<PortalItem>
Since
ArcGIS Maps SDK for JavaScript 4.1

Saves the webscene to its associated portal item. The portal item to save to must already exist and be valid. This is a convenience method that will use PortalItem.update() to store the webscene in the item. The web scene is saved according to web scene specification standards.

If the scene is displayed in a view, use updateFrom() to store the current view properties in the webscene before saving it.

const scene = new WebScene({
portalItem: {
id: "3a9976baef9240ab8645ee25c7e9c096"
}
});
const view = new SceneView({
container: "viewDiv",
map: scene
});
scene.updateFrom(view).then(function() {
scene.save();
});

Note that this saves the webscene to its existing item. Depending on how the scene is shared, users that do not own the scene may modify it. To save an existing scene as a new item owned by the user signed into the portal instance, use saveAs().

Wait until each save() operation has resolved before starting a new save() operation to avoid a potential abort-error.

The webscene will be automatically loaded if it is not already before saving.

See also
Parameters
ParameterTypeDescriptionRequired
options

Additional options.

Returns
Promise<PortalItem>

A promise that resolves with the PortalItem instance when the item has successfully been saved, or rejects otherwise.

saveAs

Method
Signature
saveAs (portalItem: PortalItemProperties, options?: SaveAsOptions): Promise<PortalItem>
Since
ArcGIS Maps SDK for JavaScript 4.1

Saves the webscene to a new portal item. If saving has completed successfully, then the saved portal item will be set in the portalItem property of the WebScene. This is a convenience method that will create a new PortalItem and use PortalUser.addItem() to store the webscene in a Portal.

Use updateFrom() to store the current view properties in the webscene before saving it.

Note that this always saves the webscene as a new portal item owned by the user performing the edits and executing the saveAs() method. If you want to modify the existing item without changing its ownership use save().

Wait until each saveAs() operation has resolved before starting a new saveAs() operation to avoid a potential abort-error.

The webscene will be automatically loaded if it is not already before saving.

See also
Parameters
ParameterTypeDescriptionRequired
portalItem

The new portal item to which the scene will be saved.

Portal item properties such as the title or description need to be explicitly set on the item and will not be automatically copied from the current associated scene portal item (if any).

options

additional save options.

Returns
Promise<PortalItem>

a promise that resolves with the PortalItem instance when the item has successfully been saved, or rejects otherwise.

Examples
const scene = new WebScene();
scene.saveAs({
// autocasts as new PortalItem()
title: "New WebScene"
});
const scene = new WebScene({
basemap: "topo-vector"
});
const view = new SceneView({
container: "viewDiv",
map: scene
});
// use updateFrom in case the webscene is displayed in a view
// to store the current view properties in the scene
scene.updateFrom(view).then(function() {
scene.saveAs({
// autocasts as new PortalItem()
title: "New WebScene"
});
});

toJSON

Method
Signature
toJSON (): Record<string, any> | null | undefined

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() topic in the Guide and the web scene specification for more information.

Returns
Record<string, any> | null | undefined

The ArcGIS portal JSON representation of an instance of this class.

updateFrom

Method
Signature
updateFrom (view: SceneView, options?: WebSceneUpdateFromOptions): Promise<void>

Update properties of the WebScene related to the view.

This should usually be called just before saving a scene. The following properties are updated from the view:

  1. initialViewProperties.spatialReference
  2. initialViewProperties.viewingMode
  3. initialViewProperties.timeExtent
  4. initialViewProperties.analyses
  5. clippingArea
  6. heightModelInfo

Depending on the provided options, the following properties are also updated:

  1. initialViewProperties.environment
  2. initialViewProperties.viewpoint
  3. thumbnail
  4. widgets
See also
Parameters
ParameterTypeDescriptionRequired
view

The view to update from.

options

Update options.

Returns
Promise<void>

Resolves when the update has completed.

updateThumbnail

Method
Signature
updateThumbnail (view: SceneView, options?: WebSceneUpdateThumbnailOptions): Promise<void>

Update the thumbnail of the WebScene by taking a screenshot of the view. Note that this is automatically called from updateFrom() unless explicitly disabled. Updating the thumbnail separate can be useful if you want to show a screenshot from a different viewpoint than what is stored in the webscene initial state.

Parameters
ParameterTypeDescriptionRequired
view

The view to update from.

options

Update options.

Returns
Promise<void>

when

inherited Method
Signature
when <TResult1 = this, TResult2 = never>(onFulfilled?: OnFulfilledCallback<this, TResult1> | null | undefined, onRejected?: OnRejectedCallback<TResult2> | null | undefined): Promise<TResult1 | TResult2>
Type parameters
<TResult1 = this, TResult2 = never>
Inherited from: EsriPromiseMixin
Since
ArcGIS Maps SDK for JavaScript 4.6

when() may be leveraged once an instance of the class is created. This method takes two input parameters: an onFulfilled function and an onRejected function. The onFulfilled executes when the instance of the class loads. The onRejected executes if the instance of the class fails to load.

Parameters
ParameterTypeDescriptionRequired
onFulfilled

The function to call when the promise resolves.

onRejected

The function to execute when the promise fails.

Returns
Promise<TResult1 | TResult2>

Returns a new promise for the result of onFulfilled that may be used to chain additional functions.

Example
// Although this example uses MapView, any class instance that is a promise may use when() in the same way
let view = new MapView();
view.when(function(){
// This function will execute once the promise is resolved
}, function(error){
// This function will execute if the promise is rejected due to an error
});
