Geometry.intersection介绍

[英]Computes a Geometry representing the point-set which is common to both this Geometry and the other Geometry.

The intersection of two geometries of different dimension produces a result geometry of dimension less than or equal to the minimum dimension of the input geometries. The result geometry may be a heterogeneous GeometryCollection. If the result is empty, it is an atomic geometry with the dimension of the lowest input dimension.

Intersection of GeometryCollections is supported only for homogeneous collection types.

Non-empty heterogeneous GeometryCollection arguments are not supported.
[中]计算表示此Geometry和other几何体共用的点集的Geometry。
两个不同尺寸的几何图形的交点生成的结果几何图形的尺寸小于或等于输入几何图形的最小尺寸。结果几何体可能是非均匀几何体集合。如果结果为空，则它是具有最低输入维度维度的原子几何体。
只有同构集合类型才支持GeometryCollection的交集。
不支持非空的异构GeometryCollection参数。
