ee.Geometry.MultiPoint.symmetricDifference

本页内容
Examples

Returns the symmetric difference between two geometries.

Usage	Returns
`MultiPoint.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.

// Define a MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);

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

// Apply the symmetricDifference method to the MultiPoint object.
var multiPointSymmetricDifference = multiPoint.symmetricDifference({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('multiPoint.symmetricDifference(...) =', multiPointSymmetricDifference);

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