Property Overview Any properties can be set, retrieved or listened to. See the Watch for changes topic.Show inherited properties Hide inherited properties
Property DetailsSince: ArcGIS Maps SDK for JavaScript 4.20 PointCloudLayer since 4.2, apiKey added at 4.20.
An authorization string used to access a resource or service. This property will append the API key to all requests made by the layer to the 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.
If loading a secure layer with API authentication via a PortalItem, the API key needs to be set on the portalItem.
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.
Since: ArcGIS Maps SDK for JavaScript 4.18 PointCloudLayer since 4.2, customParameters added at 4.18.
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"
}
});
Inherited
Property declaredClass Stringreadonly
Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.
The name of the class. The declared class name is formatted as esri.folder.className
.
Since: ArcGIS Maps SDK for JavaScript 4.4 PointCloudLayer since 4.2, elevationInfo added at 4.4.
Specifies how points are placed on the vertical axis (z). This property only affects PointCloudLayers when using the absolute-height
mode.
Defines how the points are placed on the vertical axis (z). Currently only absolute-height
mode is supported.
offset
value and the point's z-value. It doesn't take the elevation of the terrain into account. This is the only supported elevation mode for a PointCloudLayer.
The value is always "absolute-height".
offset Number|null|undefinedAn elevation offset, which is added to the vertical position of each point.
unit ElevationUnit|null|undefinedThe unit for offset
values.
An array of fields accessible in the layer. The most common fields for PointCloudLayers are described more in detail in the following table:
Example
// decode the rgb value with Arcade:
var rgb = $feature.RGB;
var red = Floor(rgb/65536,0);
var green = Floor((rgb-(red*65536))/256,0);
var blue = rgb-(red*65536)-(green*256);
return "rgb(" + red + "," + green + "," + blue + ")";
// decode the returns value with Arcade:
var returnnumber = $feature.RETURNS % 16;
var numberofreturns = Floor($feature.RETURNS / 16)
return returnnumber + " / " + numberofreturns;
Since: ArcGIS Maps SDK for JavaScript 4.13 PointCloudLayer since 4.2, fieldsIndex added at 4.13.
A convenient property that can be used to make case-insensitive lookups for a field by name. It can also provide a list of the date fields in a layer.
Example
// lookup a field by name. name is case-insensitive
const field = layer.fieldsIndex.get("SoMeFiEld");
if (field) {
console.log(field.name); // SomeField
}
Since: ArcGIS Maps SDK for JavaScript 4.10 PointCloudLayer since 4.2, filters added at 4.10.
An array of pointCloudFilters used to filter points. Only the points that satisfy all the filters are displayed in the view. There are two types of filters that can be set: PointCloudValueFilter filters points based on classification values and PointCloudReturnFilter filters points based on return values.
Example
// filter out points that don't belong to ground or building
const pcLayer = new PointCloudLayer({
...,
filters: [{
type: "value",
field: "CLASS_CODE",
mode: "include",
// values include ground(2) and building(6)
values: [2, 6]
}]
});
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;
});
Inherited
Property id String
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:
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
});
legendEnabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.5 PointCloudLayer since 4.2, legendEnabled added at 4.5.
Indicates whether the layer will be included in the legend.
Inherited
Property listMode String
Indicates how the layer should display in the LayerList widget. The possible values are listed below.
Possible Values:"show" |"hide" |"hide-children"
The Error object returned if an error occurred while loading.
Inherited
Property loadStatus Stringreadonly
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
Property loadWarnings Object[]readonly
A list of warnings which occurred while loading.
Inherited
Property loaded Booleanreadonly
Indicates whether the layer's resources have loaded. When true
, all the properties of the object can be accessed.
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.
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.
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;
An array of field names from the service to include with each feature. To fetch the values from all fields in the layer, use ["*"]
. Fields specified in outFields
will be requested alongside with required fields for rendering and filtering. The required fields and outFields
are used to populate PointCloudLayerView.availableFields.
Examples
// Includes all fields from the service in the layer
pcl.outFields = ["*"];
// Get the specified fields from the service in the layer
// These fields will be added to FeatureLayerView.availableFields
// along with rendering and labeling fields. Use these fields
// for client-side filtering and querying.
pcl.outFields = ["ELEVATION", "RGB", "CLASS_CODE];
Since: ArcGIS Maps SDK for JavaScript 4.27 Layer since 4.0, parent added at 4.27.
The parent to which the layer belongs.
persistenceEnabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.28 PointCloudLayer since 4.2, persistenceEnabled added at 4.28.
popupEnabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.13 PointCloudLayer since 4.2, popupEnabled added at 4.13.
Indicates whether to display popups when points in the layer are clicked. The layer needs to have a popupTemplate to define what information should be displayed in the popup. Alternatively, a default popup template may be automatically used if Popup.defaultPopupTemplateEnabled is set to true
.
Since: ArcGIS Maps SDK for JavaScript 4.13 PointCloudLayer since 4.2, popupTemplate added at 4.13.
The popup template for the layer. When set on the layer, the popupTemplate
allows users to access attributes and display their values in the view's Popup when a feature is selected using text and/or charts. See the PointCloudLayer.fields for the most common attributes information. See the PopupTemplate sample for an example of how PopupTemplate interacts with a FeatureLayer. Setting a PopupTemplate on this layer type is done in the same way as a FeatureLayer.
A default popup template is automatically used if no popupTemplate
has been defined when Popup.defaultPopupTemplateEnabled is set to true
.
The portal item from which the layer is loaded. If the portal item references a feature or scene service, then you can specify a single layer to load with the layerId property.
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(() => {
if (table.isTable) {
map.tables.add(table);
}
});
// 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 esri/portal/PortalItem
id: "caa9bd9da1f4487cb4989824053bb847",
// Set an API key to access a secure portal item configured with API key authentication.
apiKey: "APIKEY"
}
});
The renderer assigned to the layer. The renderer defines how to visualize each point in the layer.
Example
// all points in the layer will be colorized with the RGB attribute
layer.renderer = {
type: "point-cloud-rgb", // autocasts as new PointCloudRGBRenderer()
field: "RGB"
};
The spatial reference of the layer.
The title of the layer used to identify it in places such as the Legend and LayerList widgets.
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.
Inherited
Property uid Stringreadonly
Since: ArcGIS Maps SDK for JavaScript 4.33 Layer since 4.0, uid added at 4.33.
An automatically generated unique identifier assigned to the instance. The unique id is generated each time the application is loaded.
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.
The major version of the scene layer.
The minor version of the scene layer.
The complete version string of the scene layer.
Example
// Prints the version to the console - e.g. 1.4, 1.5, etc.
console.log(layer.version.versionString);
Since: ArcGIS Maps SDK for JavaScript 4.30 Layer 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.
Inherited
Property visible Boolean
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.
Example
// The layer is no longer visible in the view
layer.visible = false;
// Watch for changes in the layer's visibility
// and set the visibility of another layer when it changes
reactiveUtils.watch(
() => layer.visible,
(visible) => {
if (visible) {
anotherLayer.visible = true;
} else {
anotherLayer.visible = false;
}
}
);
