momepy.courtyards#
- momepy.courtyards(geometry, graph, buffer=0.01)[source]#
Calculate the number of courtyards within the joined structure.
Adapted from [Schirmer and Axhausen, 2015].
- Parameters:
- geometryGeoDataFrame
A GeoDataFrame containing objects to analyse.
- graphlibpysal.graph.Graph
A spatial weights matrix for the geodataframe, it is used to denote adjacent buildings.
- buffer: float
Buffer value for the geometry. It can be used to account for topological problems.
- Returns:
- Series
A Series containing the resulting values.
