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 | BBox.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 BBox object.
var bBox = ee.Geometry.BBox(-122.09, 37.42, -122.08, 37.43);
// Apply the area method to the BBox object.
var bBoxArea = bBox.area({'maxError': 1});
// Print the result to the console.
print('bBox.area(...) =', bBoxArea);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(bBox,
{'color': 'black'},
'Geometry [black]: bBox');
