geometry GeometryUnion

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.

Possible Values:"geodesic"|"loxodrome"|"great-elliptic"|"normal-section"|"shape-preserving"

unit AreaUnit

optional

The area unit of the return value.

Returns

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

Example

if (!geodeticAreaOperator.isLoaded()) {
  await geodeticAreaOperator.load();
}

// Calculate the geodetic area of a polygon.
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}

Loads this module's dependencies. This method must be called first if isLoaded returns false.

Returns

Type	Description
Promise	Resolves when the dependencies have been loaded.
