Geometry.getBoundary介绍

[英]Returns the boundary, or an empty geometry of appropriate dimension if this Geometry is empty. (In the case of zero-dimensional geometries, ' an empty GeometryCollection is returned.) For a discussion of this function, see the OpenGIS Simple Features Specification. As stated in SFS Section 2.1.13.1, "the boundary of a Geometry is a set of Geometries of the next lower dimension."
[中]返回边界，如果Geometry为空，则返回相应维度的空几何体。（对于零维几何图形，将返回一个空的GeometryCollection。）有关此功能的讨论，请参阅OpenGIS简单功能规范。如SFS第2.1.13.1节所述，“几何体的边界是一组下一个较低尺寸的几何体。”
