ee.Geometry.LineString.symmetricDifference

  • ThesymmetricDifference method returns the symmetric difference between two geometries.

  • It can be used with a LineString object and takes a right geometry, optional maximum error, and optional projection as arguments.

  • The result is a Geometry object.

  • The method can be used in both JavaScript and Python environments.

 Returns the symmetric difference between two geometries.

UsageReturns
LineString.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.
