Geometry.symDifference介绍

[英]Computes a Geometry representing the closure of the point-set which is the union of the points in this Geometry which are not contained in the other Geometry, with the points in the other Geometry not contained in this Geometry. If the result is empty, it is an atomic geometry with the dimension of the highest input dimension.

Non-empty GeometryCollection arguments are not supported.
[中]计算表示点集闭合的Geometry，该点集是Geometry中未包含在other几何图形中的点的并集，而other几何图形中的点未包含在Geometry几何图形中。如果结果为空，则它是维度为最高输入维度的原子几何体。
不支持非空GeometryCollection参数。
