geopandas.GeoSeries.envelope

property GeoSeries.envelope

返回一个 GeoSeries，表示每个几何体的包络线。

几何图形的包络是其边界矩形。也就是说，包含该几何图形的点或最小矩形多边形（边与坐标轴平行）。

>>> from shapely.geometry import Polygon, LineString, Point, MultiPoint
>>> s = geopandas.GeoSeries(
...     [
...         Polygon([(0, 0), (1, 1), (0, 1)]),
...         LineString([(0, 0), (1, 1), (1, 0)]),
...         MultiPoint([(0, 0), (1, 1)]),
...         Point(0, 0),
...     ]
... )
>>> s

1        LINESTRING (0 0, 1 1, 1 0)
