Shapely buffer point
WebbReturns a GeoSeries of the intersection of points in each aligned geometry with other. The operation works on a 1-to-1 row-wise manner: Parameters otherGeoseries or geometric object The Geoseries (elementwise) or geometric object to find the intersection with. alignbool (default True) If True, automatically aligns GeoSeries based on their indices. Webb17 sep. 2024 · 创建圆 In [20]: circle = Point (0, 0).buffer (10) # 创建以 (0, 0)为圆心，10为半径的圆 In [25]: circle.area # 获取创建的圆的面积 Out [25]: 313.6548490545939 从上述结果可以看出，所创建的圆的面积小于pi r^2，这是因为 buffer 方法默认参数 resolution 为16， resolution 的值越大圆越完整。
