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.

Adapted from [DPR+17].

Parameters
gdfGeoDataFrame

GeoDataFrame containing objects
