ee.Geometry.Rectangle.symmetricDifference

Returns the symmetric difference between two geometries.

Usage	Returns
`Rectangle.symmetricDifference(right, maxError, proj)`	Geometry

Argument	Type	Details
this: `left`	Geometry	The geometry used as the left operand of the operation.
`right`	Geometry	The geometry used as the right operand of the operation.
`maxError`	ErrorMargin, default: null	The maximum amount of error tolerated when performing any necessary reprojection.
`proj`	Projection, default: null	The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere.

Examples

Code Editor (JavaScript)

// Define a Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);

// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);

// Apply the symmetricDifference method to the Rectangle object.
var rectangleSymmetricDifference = rectangle.symmetricDifference({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('rectangle.symmetricDifference(...) =', rectangleSymmetricDifference);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(rectangle,
             {'color': 'black'},
             'Geometry [black]: rectangle');
Map.addLayer(inputGeom,
             {'color': 'blue'},
             'Parameter [blue]: inputGeom');
Map.addLayer(rectangleSymmetricDifference,
             {'color': 'red'},
             'Result [red]: rectangle.symmetricDifference');
