ee.Geometry.Point.symmetricDifference

Returns the symmetric difference between two geometries.

UsageReturns
Point.symmetricDifference(right, maxError, proj)Geometry
ArgumentTypeDetails
this: leftGeometryThe geometry used as the left operand of the operation.
rightGeometryThe geometry used as the right operand of the operation.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullThe 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 Point object.
var point = ee.Geometry.Point(-122.082, 37.42);

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

// Apply the symmetricDifference method to the Point object.
var pointSymmetricDifference = point.symmetricDifference({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('point.symmetricDifference(...) =', pointSymmetricDifference);

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