   A utility function to return minimum bounding box list of polygons

   :param points_collections: List of 2d points collections

   :returns: A list of bounding box (minx, miny, maxx, maxy)


.. py:function:: multipolygons_area(points_collections: Sequence[spatialtis_core.types.Points]) -> Sequence[float]

   Calculate the area of polygons using shoelace formula

   :param points_collections: List of 2d points collections, represents a list of polygons

   :returns: The area of the polygons in list


.. py:function:: points_bbox(points: spatialtis_core.types.Points) -> spatialtis_core.types.BoundingBox

   Return minimum bounding box of points

   :param points: A list of points

   :returns: The bounding box (minx, miny, maxx, maxy) or (minx, miny, minz, maxx, maxy, maxz)


.. py:function:: points_shapes(polygons: List[spatialtis_core.types.Points], method: str = 'convex', concavity: float = 1.5) -> spatialtis_core.types.Points

   Acquire multipoints (shapes) that describe the points

   :param polygons: A list of polygons
