ee.Geometry.LinearRing.symmetricDifference

  • symmetricDifference returns the symmetric difference between two geometries.

  • The method takes a right geometry operand, and optionalmaxError andproj arguments.

  • The result of the operation is a Geometry.

  • The provided examples demonstrate how to use thesymmetricDifference method in both JavaScript and Python.

 Returns the symmetric difference between two geometries.

UsageReturns
LinearRing.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.
