Method Overview

Return Type	Summary	Object
Number	Calculates the geodetic area of the input Geometry.	geodeticAreaOperator
Boolean	Indicates if all dependencies of this module have been loaded.	geodeticAreaOperator
Promise	Loads this module's dependencies.	geodeticAreaOperator

execute Method execute(geometry, options){Number}

Calculates the geodetic area of the input Geometry. Unless the unit option is set, the default is square-meters.

Parameters

Specification

geometry Geometry

The input geometry.

options Object

optional

Additional options.

Specification

curveType String

optional

Default Value: "geodesic"

The type of geodetic curve used to determine the area.

unit AreaUnit

optional

The area unit of the return value.

Returns

Type	Description
Number	Returns the geodetic area of the input geometry.

Example

// Calculate the geodetic area of a polygon.
if (geodeticAreaOperator.isLoaded()) {
 const area = geodeticAreaOperator.execute(polygon);
}

isLoaded Method isLoaded(){Boolean}

Indicates if all dependencies of this module have been loaded.

Returns

Type	Description
Boolean	Returns `true` if this module's dependencies have been loaded.

load Method load(){Promise}
