ee.Geometry.BBox.symmetricDifference

  • TheBBox.symmetricDifference method returns the symmetric difference between two geometries.

  • This method requires a left geometry (the BBox object itself) and a right geometry as inputs.

  • Optional arguments includemaxError for tolerance in reprojection andproj for specifying the coordinate system.

  • The output of thesymmetricDifference method is a Geometry object.

 Returns the symmetric difference between two geometries.

UsageReturns
BBox.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.
