ee.Geometry.Polygon.area

Returns the area of the geometry. Area of points and line strings is 0 and the area of multi geometries is the sum of the areas of their components (intersecting areas are counted multiple times).

Usage	Returns
Polygon.area(maxError, proj)	Float

Argument	Type	Details
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 Polygon object.
var polygon = ee.Geometry.Polygon(
    [[[-122.092, 37.424],
      [-122.086, 37.418],
      [-122.079, 37.425],
      [-122.085, 37.423]]]);

// Apply the area method to the Polygon object.
var polygonArea = polygon.area({'maxError': 1});

// Print the result to the console.
print('polygon.area(...) =', polygonArea);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(polygon,
             {'color': 'black'},
             'Geometry [black]: polygon');
