ee.Geometry.Rectangle.symmetricDifference
Page Summary
The
symmetricDifferencemethod returns the symmetric difference between two geometries.This method is used with a geometry as the left operand and accepts another geometry as the right operand, optionally including error margin and projection parameters.
Examples demonstrate how to use the method in both JavaScript and Python environments.
| Usage | Returns |
|---|---|
Rectangle.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. |
