esri/layers/IntegratedMesh3DTilesLayer
The IntegratedMesh3DTilesLayer is designed for visualizing accurate representations of built and natural environments in a SceneView.
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 realistic textured mesh and can include elevation information and 3D objects, such as buildings and trees. Integrated mesh layers are generally created for citywide 3D mapping; they are often captured by drone and cannot be restyled.
The IntegratedMesh3DTilesLayer loads integrated mesh data based on a hierarchical data structure defined by the 3D Tiles specification. 3D Tiles are an OGC standard used to visualize large amounts of 3D content, similar to Indexed Scene Layer (I3S) scene layers. Currently, only JPEG and PNG textures are supported for 3D Tiles data loaded using the JavaScript Maps SDK.
The 3D Tiles Service is identified by the URL of the ArcGIS Server REST resource, specifically the 3D Tiles root tileset json file:
IntegratedMesh3DTilesLayer = new IntegratedMesh3DTilesLayer({
url: "https://tiles.arcgis.com/tiles/0z60TleH1Y2qkUzY/arcgis/rest/services/Stuttgart_WGS84/3DTilesServer/tileset.json"
});

Property Details
-
An authorization string used to access a resource or service. API keys are generated and managed in the portal. 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" });
-
A list of custom parameters appended to the URL of all resources fetched by the layer. It's an object with key-value pairs where value is a string. The layer's
refresh()
method needs to be called if the customParameters are updated at runtime.Example// send a custom parameter to your special service let layer = new MapImageLayer({ url: serviceUrl, customParameters: { "key": "my-special-key" } });
-
elevationInfo
elevationInfo Object
-
Specifies how the mesh is placed on the vertical axis (z). This property only affects IntegratedMesh3DTilesLayers when using the
absolute-height
mode. Integrated mesh 3D Tiles 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 IntegratedMesh3DTilesLayer.The value is always "absolute-height".
optional An elevation offset, which is added to the vertical position of the mesh.
unit ElevationUnit|null|undefinedThe unit for
offset
values.
-
Inherited from Layer
-
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; });
-
listMode
InheritedPropertylistMode String
Inherited from Layer -
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"
-
loadStatus
InheritedPropertyloadStatus Stringreadonly
Inherited from Layer -
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
-
Inherited from Layer
-
A list of warnings which occurred while loading.
-
maxScale
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
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;
-
parent
InheritedPropertyparent Map |Basemap |Ground |GroupLayer |CatalogDynamicGroupLayer |CatalogLayer
Inherited from Layer -
The parent to which the layer belongs.
-
persistenceEnabled
persistenceEnabled Boolean
-
- Default Value:true
-
portalItem
portalItem PortalItem |null |undefined
-
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
spatialReference SpatialReferenceautocast
-
The spatial reference of the layer.
-
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. 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
type Stringreadonly
-
For IntegratedMesh3DTilesLayer the type is always "integrated-mesh-3dtiles".
-
url
url String
-
The URL of the root json file.
-
visibilityTimeExtent
InheritedPropertyvisibilityTimeExtent TimeExtent |null |undefinedautocast
Inherited from LayerSince: ArcGIS Maps SDK for JavaScript 4.30Layer since 4.0, visibilityTimeExtent added at 4.30. -
Specifies a fixed time extent during which a layer should be visible. This property can be used to configure a layer that does not have time values stored in an attribute field to work with time. Once configured, the TimeSlider widget will display the layer within the set time extent. In the case that only one of the start or end date values are available, the layer remains visible indefinitely in the direction where there is no time value.
Aerial imagery can capture seasonal variations in vegetation, water bodies, and land use patterns. For example, in agricultural regions, aerial imageries taken during different growing seasons provide insights into crop health and productivity. Defining a fixed time extent on imageries from specific time periods provides temporal context and facilitates focused analysis based on specific time periods or events.
- Default Value:null

-
visible
InheritedPropertyvisible Boolean
Inherited from Layer -
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
InheritedMethodload(signal){Promise}
Inherited from Layer -
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 aLoadable
instance load status. When the signal is aborted, the instance does not stop its loading process, only cancelLoad can abort it.Parametersignal AbortSignaloptionalSignal 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
