momepy.Squareness#

class momepy.Squareness(gdf, verbose=True)[source]#

Calculates the squareness of each object in a given GeoDataFrame. Uses only external shape (shapely.geometry.exterior), courtyards are not included.

Returns np.nan for MultiPolygons.

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

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

Parameters
gdfGeoDataFrame

A GeoDataFrame containing objects.

verbosebool (default True)

If True, shows progress bars in loops and indication of steps.

Examples

>>> buildings_df['squareness'] = momepy.Squareness(buildings_df).series

>>> buildings_df.squareness[0]
3.7075816043359864
Attributes
