momepy.CentroidCorners¶

class momepy.CentroidCorners(gdf)[source]¶

Calculates mean distance centroid - corners and st. deviation.

\[\overline{x}=\frac{1}{n}\left(\sum_{i=1}^{n} dist_{i}\right);\space \mathrm{SD}=\sqrt{\frac{\sum|x-\overline{x}|^{2}}{n}}\]

Parameters

gdfGeoDataFrame

GeoDataFrame containing objects
