get_polygon(polygon_collection, point):forpolygoninpolygon_collection:ifpolygon.intersects(point):returnpolygonreturnNone Run Code Online (Sandbox Code Playgroud) 这种方法有效,但它在 O(n) * O(单多边形检查)中。如果构建树数据结构,这肯定可以减少到 O(log(n)) * O(单多边形检查)。

In shapely 1.8 I am getting a warning when subclassing Point (or any other geom) when I add a property (e.g., label: str): from shapely.geometry import Point class LabeledPoint(Point): def __init__(self, label: str, *args) -> None: self...

如何在Python中使用geopandas测试Point是否在Polygon/Multipolygon中? 、、、 两者都是dtype:geometry.我认为我可以很容易地进行比较,但当我使用我的代码时,我得到的每个点的答案都是假的。即使在美国也有积分。代码是: import geopandas as gpimport xlsxwriterfromshapely.geometry import 浏览...
参考:Cut a polygon with two lines in Shapely参考:shapely官方文档——Splitting 切割后得到一个多边形集合,通过遍历可以获取每一个 geometry 的具体信息。 代码语言:javascript 复制 from shapely.geometryimportPolygon,Point,LineString poly_1=Polygon([(0,0),(0,2),(2,2),(2,0)])line_1=LineString([...
