- shapely.ops.polylabel(polygon, tolerance)
Finds the approximate location of the pole of inaccessibility for a given polygon. Based on Vladimir Agafonkin’s polylabel.
找到给定多边形的极点（即离多边形轮廓最远的内部点，但不要与中心点混淆）大致位置。基于Vladimir Agafonkin的polylabel。
New in version 1.6.0
| Note |
| Prior to 1.7 polylabel must be imported from shapely.algorithms.polylabel instead of shapely.ops. 在1.7之前，polylabel必须从shapely.algorithms.polylabel而不是shapely.ops导入。 |
>>> from shapely.ops import polylabel
>>> polygon = LineString([(0, 0), (50, 200), (100, 100), (20, 50),
(-100, -20), (-150, -200)]).buffer(100)
>>> label = polylabel(polygon, tolerance=10)
>>> label.wkt
'POINT (59.35615556364569 121.8391962974644)'
