Methods

static computeArea(positions){Array.<Cartesian3>}

Calculate the area in square meters (m2) based on a series of Cartesian coordinate points.

Name Type Description
positions Array

The coordinates of each point on the surface.
Returns:
Type Description
Array.<Cartesian3> The area of this region.

activate()

Activate the measurement processor.

clear()

Clear all elements related to measurement.

deactivate()

Turn off the measurement processor.

destroy()

Clear the measurement results, turn off the measurement processor, and destroy the captured object resources held. Once the object is destroyed, it should not be called again. Calling any function will result in a Developer Error exception. Therefore, follow the method in the example to assign the return value (undefined) to the object

Example
handler = handler && handler.destroy();

getLinePositions(){Array.<Cartesian3>}

Obtain the set of measurement line positions

Returns:
Type Description
Array.<Cartesian3> Cartesian coordinate point array.
