momepy.stroke_orthogonality#
- momepy.stroke_orthogonality(stroke_graph)[source]#
Computes the stroke’s orthogonality. Orthogonality is defined as the average of the sine of the minimum angles between the stroke and the street segments it intersects:
\[O(s)=\frac{\sum_{i\in A}sin(\theta_i)}{C(s)}\]Where \(\theta_i\) is the minimum angle between the street segment \(i\) and the stroke \(s\), and \(C(s)\) is the connectivity of the stroke \(s\).
Its value vary between 0 and 1, for low to right angles.

- Parameters:
- stroke_graph: nx.Graph()
Stroke graph of a network, generated with momepy.coins_to_nx().
- Returns:
- stroke_graph: nx.Graph()
Returns stroke_graph where each node has acquired the additional attribute stroke_orthogonality; and the additional attribute stroke_connectivity (unless it has been present in the input graph).
Examples
>>> stroke_graph = stroke_orthogonality(stroke_graph)
