Represents the analysis view of a VolumeMeasurementAnalysis after it has been added to SceneView.analyses.
The VolumeMeasurementAnalysisView3D is responsible for rendering a VolumeMeasurementAnalysis using custom visualizations. The properties on the analysis view provide developers with the ability to query measured results. If the result is unavailable, the error property provides the details on the cause.
The view for an analysis can be retrieved using SceneView.whenAnalysisView() similar to how layer views are retrieved for layers using SceneView.whenLayerView().
// retrieve analysis view for analysisconst analysis = new VolumeMeasurementAnalysis();view.analyses.add(analysis); // add to the scene viewconst analysisView = await view.whenAnalysisView(analysis);Things to consider:
- When using the "cut-fill" VolumeMeasurementAnalysis.measureType in interactive mode, hover over the shift manipulator, press
Tabto activate the tooltip input mode, and enter the elevation of the target surface. - Snapping is enabled by default. This can be temporarily disabled by holding the
CTRLkey. - Layer types currently supported for snapping are: FeatureLayer, GraphicsLayer (except Mesh geometries), GeoJSONLayer, WFSLayer, CSVLayer, 3D Object SceneLayer, and BuildingSceneLayer.

error
- Type
- VolumeMeasurementError | null | undefined
Error encountered while calculating the analysis result. The error has well defined names that can be used to provide specific error feedback to the user. See VolumeMeasurementError for the list of possible error names.
result
- Type
- VolumeMeasurementResult | null | undefined
Result of the volume measurement. Results are calculated asynchronously and should be watched for changes.

emit
- Signature
-
emit <Type extends EventNames<this>>(type: Type, event?: this["@eventTypes"][Type]): boolean
- Type parameters
- <Type extends EventNames<this>>
Emits an event on the instance. This method should only be used when creating subclasses of this class.
hasEventListener
- Signature
-
hasEventListener <Type extends EventNames<this>>(type: Type): boolean
- Type parameters
- <Type extends EventNames<this>>
Indicates whether there is an event listener on the instance that matches the provided event name.
Parameters
| Parameter | Type | Description | Required |
|---|---|---|---|
| type | Type | The name of the event. | |
- Returns
- boolean
Returns true if the class supports the input event.
isFulfilled
- Signature
-
isFulfilled (): boolean
isFulfilled() may be used to verify if creating an instance of the class is fulfilled (either resolved or rejected).
If it is fulfilled, true will be returned.
- Returns
- boolean
Indicates whether creating an instance of the class has been fulfilled (either resolved or rejected).
isRejected
- Signature
-
isRejected (): boolean
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
- Signature
-
isResolved (): boolean
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.
on
- Signature
-
on <Type extends EventNames<this>>(type: Type, listener: EventedCallback<this["@eventTypes"][Type]>): ResourceHandle
- Type parameters
- <Type extends EventNames<this>>
Registers an event handler on the instance. Call this method to hook an event with a listener.
Parameters
| Parameter | Type | Description | Required |
|---|---|---|---|
| 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).Property Type Description remove Function When 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);}); place
- Signature
-
place (options?: AbortOptions | null | undefined): Promise<VolumeMeasurementPlacementResult>
Starts the interactive placement of a new polygon for the volume measurement analysis.
If the analysis does not have a VolumeMeasurementAnalysis.geometry yet, the method allows drawing it interactively in the view. Otherwise, clicking in the view will remove the previous geometry and start a new placement operation.
The placement operation will finish when the user presses the escape key. To stop the placing programmatically, pass an abort signal as an argument when calling the method.
Calling this method sets interactive to true.
Parameters
| Parameter | Type | Description | Required |
|---|---|---|---|
| options | An object specifying additional options. | |
- Returns
- Promise<VolumeMeasurementPlacementResult>
A promise which resolves when the operation is completed successfully or rejected if it is canceled.
Example
// cancel the placement operation at some later point// by calling abortController.abort()const abortController = new AbortController();
try { await analysisView.place({ signal: abortController.signal });} catch (error) { if (error.name === "AbortError") { console.log("Placement operation was cancelled."); }} when
- Signature
-
when <TResult1 = this, TResult2 = never>(onFulfilled?: OnFulfilledCallback<this, TResult1> | null | undefined, onRejected?: OnRejectedCallback<TResult2> | null | undefined): Promise<TResult1 | TResult2>
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
| Parameter | Type | Description | Required |
|---|---|---|---|
| onFulfilled | OnFulfilledCallback<this, TResult1> | null | undefined | 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
onFulfilledthat 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 waylet 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});
