AMD: require(["esri/layers/IntegratedMeshLayer"], (IntegratedMeshLayer) => { /* code goes here */ });
ESM: import IntegratedMeshLayer from "@arcgis/core/layers/IntegratedMeshLayer.js";
Class: esri/layers/IntegratedMeshLayer
Inheritance: IntegratedMeshLayer Layer Accessor
Since: ArcGIS Maps SDK for JavaScript 4.1

The IntegratedMeshLayer is designed for visualizing accurate representations in a SceneView of infrastructure and natural landscapes that are difficult to access.

Integrated mesh data is typically captured by an automated process for constructing 3D objects from large sets of overlapping imagery. The result integrates the original input image information as a textured mesh using a triangular interlaced structure. An integrated mesh can represent built and natural 3D features, such as building walls, trees, valleys, and cliffs, with realistic textures. Integrated mesh scene layers will always render in front of the ground surface. They are generally created for citywide 3D mapping and can be created using Drone2Map for ArcGIS, which can then be shared to ArcGIS for Desktop or web apps.

integratedmeshlayer

The Scene Service is identified by the URL of the ArcGIS Server REST resource:

IntegratedMeshLayer = new IntegratedMeshLayer({
  url: "https://tiles.arcgis.com/tiles/u0sSNqDXr7puKJrF/arcgis/rest/services/Frankfurt2017_v17/SceneServer/layers/0"
});

If the service is requested from a different domain, a CORS enabled server or a proxy is required.

Property Details

apiKey String
Since: ArcGIS Maps SDK for JavaScript 4.20

An authorization string used to access a resource or service. API keys are generated and managed in the ArcGIS Developer dashboard. An API key is tied explicitly to an ArcGIS account; it is also used to monitor service usage. Setting a fine-grained API key on a specific class overrides the global API key.

Example
// set the api key to access a protected service
const layer = new FeatureLayer({
  url: serviceUrl,
  apiKey: "YOUR_API_KEY"
});

The copyright text as defined by the scene service.

declaredClass Stringreadonly inherited
Since: ArcGIS Maps SDK for JavaScript 4.7

The name of the class. The declared class name is formatted as esri.folder.className.

elevationInfo Object
Since: ArcGIS Maps SDK for JavaScript 4.5

Specifies how the mesh is placed on the vertical axis (z). This property only affects IntegratedMeshLayers when using the absolute-height mode. Integrated mesh layers always render in front of the ground surface, so setting negative offset values will not render them below the ground.

Properties
mode String

Defines how the mesh is placed on the vertical axis (z). Currently only absolute-height is supported.

Mode Description
absolute-height The mesh is placed at an absolute elevation (z-value) above sea level. This z-value is determined by summing up the offset value and the mesh's z-value. It doesn't take the elevation of the terrain into account. This is the only supported elevation mode for an IntegratedMeshLayer.
offset Number
optional
Default Value:0

An elevation offset, which is added to the vertical position of the mesh.

unit String
optional
Default Value:meters

The unit for offset values.

Possible Values:"feet"|"meters"|"kilometers"|"miles"|"us-feet"|"yards"

The full extent of the layer. By default, this is worldwide. This property may be used to set the extent of the view to match a layer's extent so that its features appear to fill the view. See the sample snippet below.

Example
// Once the layer loads, set the view's extent to the layer's fullextent
layer.when(function(){
  view.extent = layer.fullExtent;
});

The unique ID assigned to the layer. If not set by the developer, it is automatically generated when the layer is loaded.

layerId 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
});
listMode String inherited

Indicates how the layer should display in the LayerList widget. The possible values are listed below.

Value Description
show The layer is visible in the table of contents.
hide The layer is hidden in the table of contents.
hide-children If the layer is a GroupLayer, BuildingSceneLayer, KMLLayer, MapImageLayer, TileLayer or WMSLayer, hide the children layers from the table of contents.

Possible Values:"show"|"hide"|"hide-children"

Default Value:"show"
loaded Booleanreadonly inherited

Indicates whether the layer's resources have loaded. When true, all the properties of the object can be accessed.

Default Value:false
loadError Errorreadonly inherited

The Error object returned if an error occurred while loading.

Default Value:null
loadStatus Stringreadonly inherited

Represents the status of a load operation.

Value Description
not-loaded The object's resources have not loaded.
loading The object's resources are currently loading.
loaded The object's resources have loaded without errors.
failed The object's resources failed to load. See loadError for more details.

Possible Values:"not-loaded"|"loading"|"failed"|"loaded"

Default Value:not-loaded
loadWarnings Object[]readonly inherited

A list of warnings which occurred while loading.

maxScale Number

The maximum scale (most zoomed in) at which the layer is visible in the view. If the map is zoomed in beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a maximum scale. The maxScale value should always be smaller than the minScale value, and greater than or equal to the service specification.

Default Value:0
Examples
// The layer will not be visible when the view is zoomed in beyond a scale of 1:1,000
layer.maxScale = 1000;
// The layer's visibility is not restricted to a maximum scale.
layer.maxScale = 0;
minScale Number

The minimum scale (most zoomed out) at which the layer is visible in the view. If the map is zoomed out beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a minimum scale. The minScale value should always be larger than the maxScale value, and lesser than or equal to the service specification.

Default Value:0
Examples
// The layer will not be visible when the view is zoomed out beyond a scale of 1:3,000,000
layer.minScale = 3000000;
// The layer's visibility is not restricted to a minimum scale.
layer.minScale = 0;
modifications SceneModifications
Since: ArcGIS Maps SDK for JavaScript 4.16

A collection of SceneModification with polygons and types to apply client-side modifications. Modifications are not affected by the offset from elevationInfo. With WebScene.save() the SceneModifications can be persisted. This allows you to share the modified integrated mesh through web scenes. The following modifications can be applied to the integrated mesh:

Illustration Modification Description
modification-type-clip clip - removes selected area Clip-out portions of the integrated mesh to see features below. For example, utility work on gas or water lines in an area. Planners can create a scene in which the integrated mesh is clipped out at a site to expose the water or gas lines below it.
modification-type-mask mask - displays only selected area Define an area of interest. Use a polygon and draw only parts of the integrated mesh inside that polygon. For example, if you want to show only a portion of an integrated mesh within the boundaries of a city.
modification-type-replace replace - flattens selected area Replace an area of an integrated mesh based on a 3D polygon. For example, to add constructed buildings, flatten the integrated mesh at the footprint of a building so the new building can be visualized. Create different scenarios of the new construction area and share the scenarios as a web scene to discuss with stakeholders. The integrated mesh flattens to the minimum z-vertex of the modification polygon.

The modifications for IntegratedMeshLayer need to be in the same spatial reference as the IntegratedMeshLayer. Reprojection between WGS84 and WebMercator will be done automatically. Reprojection of the geometry to other spatial references can be done with the client-side projection engine.

See also
Example
// create the IntegratedMeshLayer
const layer = new IntegratedMeshLayer({ ... })

// create a polygon
const polygon = new Polygon({ ... });

// create the modifications
let modifications = new SceneModifications(
  [
    new SceneModification({geometry: polygon, type: 'replace'})
  ]);

// add the modification to the IntegratedMesh
layer.modifications = modifications;
Since: ArcGIS Maps SDK for JavaScript 4.27

The parent to which the layer belongs.

portalItem PortalItem

The portal item from which the layer is loaded. If the portal item references a Feature Service or Scene Service, then you can specify a single layer to load with the layerId property.

Beginning with version 4.17, it is possible to load tables from feature service items hosted in ArcGIS Online and ArcGIS Enterprise. This only applies to feature layers, and will successfully load if FeatureLayer.isTable returns true.

Examples
// While this example uses FeatureLayer, this same pattern can be
// used for other layers that may be loaded from portalItem ids.
const layer = new FeatureLayer({
  portalItem: {  // autocasts as new PortalItem()
    id: "caa9bd9da1f4487cb4989824053bb847"
  }  // the first layer in the service is returned
});
// Set hostname when using an on-premise portal (default is ArcGIS Online)
// esriConfig.portalUrl = "http://myHostName.esri.com/arcgis";

// While this example uses FeatureLayer, this same pattern can be
// used for SceneLayers.
const layer = new FeatureLayer({
  portalItem: {  // autocasts as new PortalItem()
    id: "8d26f04f31f642b6828b7023b84c2188"
  },
  // loads the third item in the given feature service
  layerId: 2
});
// Initialize GeoJSONLayer by referencing a portalItem id pointing to geojson file.
const layer = new GeoJSONLayer({
  portalItem: new PortalItem({
    id: "81e769cd7031482797e1b0768f23c7e1",
    // optionally define the portal, of the item.
    // if not specified, the default portal defined is used.
    // see https://developers.arcgis.com/javascript/latest/api-reference/esri-config.html#portalUrl
    portal: new Portal({
      url: "https://jsapi.maps.arcgis.com/"
    })
  }
});
// This snippet loads a table hosted in ArcGIS Online.
const table = new FeatureLayer({
  portalItem: { // autocasts as esri/portal/PortalItem
    id: "123f4410054b43d7a0bacc1533ceb8dc"
  }
});

// Before adding the table to the map, it must first be loaded and confirm it is the right type.
table.load().then(function() {
  if (table.isTable) {
    map.tables.add(table);
  }
});
spatialReference SpatialReferenceautocast

The spatial reference of the layer.

title String

The title of the layer used to identify it in places such as the LayerList widget.

When loading a layer by service url, the title is derived from the service name. If the service has several layers, then the title of each layer will be the concatenation of the service name and the layer name. When the layer is loaded from a portal item, the title of the portal item will be used instead. Finally, if a layer is loaded as part of a webmap or a webscene, then the title of the layer as stored in the webmap/webscene will be used.

type Stringreadonly

For IntegratedMeshLayer the type is always "integrated-mesh".

url String

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 Objectreadonly

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

Properties
major Number

The major version of the scene layer.

minor Number

The minor version of the scene layer.

versionString String

The complete version string of the scene layer.

See also
Example
// Prints the version to the console - e.g. 1.4, 1.5, etc.
console.log(layer.version.versionString);
visible Boolean inherited

Indicates if the layer is visible in the View. When false, the layer may still be added to a Map instance that is referenced in a view, but its features will not be visible in the view.

Default Value:true
Example
// The layer is no longer visible in the view
layer.visible = false;

load(signal){Promise}inherited

Loads the resources referenced by this class. This method automatically executes for a View and all of the resources it references in Map if the view is constructed with a map instance.

This method must be called by the developer when accessing a resource that will not be loaded in a View.

The load() method only triggers the loading of the resource the first time it is called. The subsequent calls return the same promise.

It's possible to provide a signal to stop being interested into a Loadable instance load status. When the signal is aborted, the instance does not stop its loading process, only cancelLoad can abort it.

Parameter
signal AbortSignal
optional

Signal object that can be used to abort the asynchronous task. The returned promise will be rejected with an Error named AbortError when an abort is signaled. See also AbortController for more information on how to construct a controller that can be used to deliver abort signals.

Returns
Type Description
Promise Resolves when the resources have loaded.
on(type, listener){Object}inherited

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");
when(callback, errback){Promise}inherited
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: a callback function and an errback function. The callback executes when the instance of the class loads. The errback executes if the instance of the class fails to load.

Parameters
callback Function
optional

The function to call when the promise resolves.

errback Function
optional

The function to execute when the promise fails.

Returns
Type Description
Promise Returns a new promise for the result of callback that may be used to chain additional functions.
