pointpats.mean_center¶

pointpats.mean_center(points)[source]¶

pointpats.mean_center(points: ndarray) → ndarray[tuple[Any, ...], dtype[float64]]

pointpats.mean_center(points: GeoPandasBase) → Point

Find mean center of a point array.

Parameters:

pointsarraylike: array representing a point pattern

Returns:

center: center of a given point pattern

Examples

>>> import numpy as np
>>> import geopandas as gpd

Create an array of point coordinates.

>>> coords = np.array(
...     [
...         [66.22, 32.54],
...         [22.52, 22.39],
...         [31.01, 81.21],
...         [9.47, 31.02],
...         [30.78, 60.10],
...         [75.21, 58.93],
...         [79.26, 7.68],
...         [8.23, 39.93],
...         [98.73, 77.17],
...         [89.78, 42.53],
...         [65.19, 92.08],
...         [54.46, 8.48],
...     ]
... )

Passing an array of coordinates returns an array capturing the center.

>>> mean_center(coords)
array([52.57166667, 46.17166667])

Passing a GeoPandas object returns a shapely geometry.

>>> geoms = gpd.GeoSeries.from_xy(*coords.T)
>>> mean_center(geoms)
<POINT (52.572 46.172)>
