ee.Geometry.Rectangle.area
Stay organized with collections
Save and categorize content based on your preferences.
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 | Rectangle.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 Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);
// Apply the area method to the Rectangle object.
var rectangleArea = rectangle.area({'maxError': 1});
// Print the result to the console.
print('rectangle.area(...) =', rectangleArea);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(rectangle,
{'color': 'black'},
'Geometry [black]: rectangle');
