momepy.Squareness¶

class momepy.Squareness(gdf)[source]¶

Calculates squareness of each object in given geoDataFrame.

Uses only external shape (shapely.geometry.exterior), courtyards are not included.

\[\mu=\frac{\sum_{i=1}^{N} d_{i}}{N}\]

where d is the deviation of angle of corner i from 90 degrees.

Parameters

gdfGeoDataFrame

GeoDataFrame containing objects
