Since: ArcGIS Maps SDK for JavaScript 4.26

Input parameters used by the ImageryLayer.measurePointOrCentroid() or measurePointOrCentroid() methods to perform imagery point or centroid mensuration. The point mensuration determines the location of point-based geographic coordinates while the centroid mensuration determines the centroid of the area of interest for given geometry.

declaredClass

readonlyinherited Property

Type: string

Inherited from: Accessor

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

geometry

autocast Property

Type: Point | Extent | Polygon

Input geometry to determine a point location or a centroid of a given area.

is3D

Property

Type: boolean

When true, this method calculates the z-value for the returned point geometry. 3D calculation can only be done when the layer's capabilities.mensuration.supports3D returns true.

Default value: false

mosaicRule

autocast inherited Property

Type: MosaicRule | null | undefined

Inherited from: BaseImageMeasureParameters

Since: ArcGIS Maps SDK for JavaScript 4.27

Specifies the mosaic rule on how individual images should be mosaicked when the measure is computed. When a mosaic rule is not specified, the current settings on the ImageryLayer.mosaicRule will be used.

pixelSize

autocast inherited Property

Type: Point

Inherited from: BaseImageMeasureParameters

Since: ArcGIS Maps SDK for JavaScript 4.27

Specifies the pixel size. If pixel size is not specified, pixelSize will default to the base resolution of the image service. The raster at the specified pixel size in the mosaic dataset will be used for the Measure calculation.

type

readonly Property

Type: "point"

The string value representing the type of imagery mensuration.

fromJSON

inheritedstatic Method

Signature: fromJSON (json: any): any

Inherited from: JSONSupportMixin

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. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameters

Parameter	Type	Description	Required
json	`any`	A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns: any
Returns a new instance of this class.

toJSON

inherited Method

Signature: toJSON (): any

Inherited from: JSONSupportMixin

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns: any
The ArcGIS portal JSON representation of an instance of this class.
