AI-generated Key Takeaways
-
The
areamethod returns the area of a geometry, with points and line strings having an area of 0 and multi geometries having an area equal to the sum of their components. -
The method takes optional
maxErrorandprojarguments to specify the maximum tolerated error during reprojection and the desired output projection, respectively. -
The method returns a Float value representing the calculated area.
| Usage | Returns |

this:
geometry
|
Geometry | The geometry input. |
maxError
|
ErrorMargin, default: null | The maximum amount of error tolerated when performing any necessary reprojection. |
proj
|
Projection, default: null | If specified, the result will be in the units of the coordinate system of this projection. Otherwise it will be in square meters. |
Examples
Code Editor (JavaScript)
// Define a Point object. var point = ee . Geometry . Point ( - 122.082 , 37.42 ); // Apply the area method to the Point object. var pointArea = point . area ({ 'maxError' : 1 }); // Print the result to the console. print ( 'point.area(...) =' , pointArea ); // Display relevant geometries on the map. Map . setCenter ( - 122.085 , 37.422 , 15 ); Map . addLayer ( point , { 'color' : 'black' }, 'Geometry [black]: point' );
